Where Did The Yagi Antenna Get Its Name?




In the cellular world, one type of antenna is well known for its excellent performance, high gain, and ability to bring a signal into even the weakest of areas. The Yagi antenna, commonly mispronounced as Yogi, Yago, Yaygee, Yeahgee, etc. (we’ve heard it all!) is an antenna design that has been around longer than you may realize.


The first thing to clear up, Yagi isn’t a company or a specific product, rather it is an antenna design. A Yagi typically has a horizontal element, with directors and reflectors, making a rectangular or triangular shape depending on the frequencies it is tuned for. TV antennas of the last century were typically large antennas with exposed elements, while smaller cellular antennas tend to be housed in enclosures while still containing the same components.


(Dr. Yagi)

Now for the name. The Yagi antenna was developed by two people in the early 1920’s at the Tohoku Imperial University in Japan. Dr. Shintaro Uda and Dr. Hidetsugu Yagi were working with antennas in an attempt to try and make them more directional. While it isn’t totally clear as to why, the antenna was credited mainly to Dr. Yagi who applied for the original patent in Japan and the US. Dr. Yagi took his antenna through the US to discuss ‘his’ antenna at various conferences and to pitch ‘his’ antenna to radio engineering companies. Over time, the antenna would stop being known by its proper name, the ‘wave projector directional antenna’ and would be known simply as the ‘Yagi antenna.’

The Yagi antenna makes numerous appearances from different cellular manufacturers, in amplifier and repeater kits, and can be a powerful tool when used in modem LTE networks for MiMo operation. You can learn more about MiMo in our recent article, Mimo for 4G LTE Routers and When You Need It (and When You Don’t).


When considering an antenna, the Yagi is a powerful tool but it does have a couple of drawbacks. Because this is directional, you need to have line of sight to the tower, or at least know where the tower is so you can aim the antenna. If you have major obstructions between you and the cell tower, you may need to aim the antenna in a different direction or try another antenna all together. A poorly aimed Yagi will perform worse than a lower gain omnidirectional antenna if aimed improperly.

NetComm Wireless NTC-140W Review

Available at 3Gstore, the NetComm NTC-140W is a powerful tool for industrial M2M and IoT applications. Significant features in a user friendly package make the 140W an easy choice for new networks or upgrading older hardware.



The NetComm NTC-140W is built with harsh environments in mind. The ruggedized enclosure and device can withstand temperatures operating temperature from -40f to 185f, significantly higher than other industrial routers which cap out in the 150f range. That may seem excessive, but when you consider automotive or industrial deployments where the router may be subject to extreme heat or cold, the operating temperatures of the 140W ensure reliable operation in the most extreme environments.

As an industrial device, there are also multiple power options available. Included with the NTC-140W is a hardwire harness that connects to a 4 pin molex connector. This means you have 2 cables for power, and 2 cables for programmable I/O operations on the router. In a vehicle application you can have ignition sensing to power the router on with the vehicle to save power. The 140W also accepts 8-40V DC for an incredibly wide range of operating voltages from solar power supplies through high voltage industrial control panels. An optional AC adapter is available for those that don’t need a hardwired power connection.



There are 2 Gigabit ethernet ports for LAN/WAN connectivity, the multipurpose I/O and power supply, and a micro USB 2.0 OTG interface (discussed later). The SIM card for the cellular radio inserts with a lockable tray and uses standard 2FF sized SIM cards. 3FF Micro or 4FF Nano SIM cards can be used with a SIM adapter. There are 2 SMA connectors for cellular signal, 2 RP-SMA connectors for WiFi, and an SMA connector for GPS functionality. A multi-function reset button lets you reboot, load into recovery mode, or factory default the unit. Status LEDs provide clear indications of signal strength, network status, or any errors that need to be addressed.



Once logged into the web user interface for the NetComm NTC-140W, you’ll find a clean and easy to understand configuration screen. A helpful but not overloaded main status page tells you everything you need to know from system information to cellular status. The web UI isn’t cluttered, but it isn’t lacking in features either. System logging, firmware management, diagnostics, port forwarding and firewall settings, and more, are easily found and changed. Aside from the web GUI, many other configuration and control options are available. Telnet into the device for status monitoring and configuration, SNMP allows for easy integration into existing systems, a TR-069 client configuration is supported for advanced users, and SMS controls (text messages) allow for simple remote management. With SMS commands you can request advanced diagnostics like signal strength, IP, uptime, and more. You can also remotely configure a device's APN to get an NTC-140W connected without any hands on time. Multiple commands can be executed as well for reboot, reset, and more.

The NTC-140W is more than just a cellular only router. This also functions as a powerful failover unit using a wired WAN connection as a primary connection with cellular as a backup. There is nothing worse than having critical applications go offline, and having to send a tech out into the field to troubleshoot only to find out the issue lies with the ISP. The 140W will save time and money from expensive truck rolls, and stop lost productivity from remote sites and equipment that have gone offline.


(263 Days of Uptime as of this Post!

The NetComm NTC-140W runs on top of an embedded Linux 3.6 kernel and a full SDK is available for download. With the SDK you can create and install custom applications and run them directly from the router. Internal flash storage is available for use and can be extended with the USB connection if more resource intensive applications (like on site data logging) are required.



When it comes to mission critical applications such as primary connection backup, surveillance, point of sale, digital signage, remote monitoring, in-vehicle communications, and more, the NetComm NTC140W is a powerful tool and a major contender in the M2M and IoT world.

Verizon Acquires Straight Path - Accelerates 5G Launch


In a press release today, Verizon has announced a massive purchase of Straight Path, a major holder in high frequency wireless spectrum. AT&T was previously in the running to acquire this spectrum holding company but in a power play, Verizon has stepped in. This move will give Verizon massive coverage in high frequencies which are critical to the launch of 5G networks based on millimeter wave technology. T-Mobile on the other hand plans to deploy their 5G network on their 600Mhz low frequency licences which will give the carrier excellent building coverage with the least amount of time to deploy vs high frequencies which will need base stations and many antennas to pass the signal to new areas.

"Verizon now has all of the pieces in place to quickly accelerate the deployment of 5G," said Hans Vestberg, executive vice president and president of global network and technology at Verizon. "Combined with our recent transactions with Corning Incorporated, XO Communications, and Prysmian Group, this is another step to build the next-generation network for our customers."

WilsonPro 1050 Announcement




ST GEORGE, UT–(Marketwired – May 8, 2017) – WilsonPro, the leader in enterprise cellular connectivity, announced today the availability of the WilsonPro 1050. The Pro 1050 is the industry’s first Federal Communications Commission (FCC) and wireless carrier-approved „inline” cellular booster system. The Pro 1050 is the only passive distributed antenna system (DAS) with a unique dual-amplifier design to compensate for cell signal that is lost over long lengths of cable.

“WilsonPro’s powerful passive cellular boosters are the only solutions that give businesses the benefits of an active DAS without the high cost or lengthy implementation,” said Bruce Lancaster, CEO of Wilson Electronics. „The Pro 1050 goes one step further to minimize lost cell signal along a cable run to ensure a strong, uninterrupted cell signal throughout the entire building. Strong cell signal is essential for a company’s overall efficiency and effectiveness and WilsonPro strives to create effective products at a fraction of the cost of alternative solutions.”


The Pro 1050 amplifies weak cell signal to provide reliable voice and data coverage, including 4G LTE, in any large commercial space such as hotels, hospitals, retail spaces, large residential buildings and event venues. Typically, as cell signal moves over long lengths of coaxial cable, some of the signal is lost, reducing overall booster system performance. The Pro 1050 solves this issue by using a dual-amplifier system, which consists of a main amplifier and a supplementary inline amplifier. Working together, the two amplifiers determine the actual signal that is lost along the cable run and boost the signal accordingly to compensate for up to 300 feet of cable. The enhanced signal results in cell service that is up to 32 times stronger, increased data speeds and fewer missed or dropped calls.

The Pro 1050’s self-optimizing design makes it quick and easy to install unlike active DAS, which can take years to implement. The Pro 1050 works with all North American cellular networks, simultaneously boosting all carrier signals at the same time. The Pro 1050 features eXtended Dynamic Range (XDR) technology and will never overpower and shut down, no matter how strong the outside cellular signals are. Like all WilsonPro cellular signal boosters, the Pro 1050 features cell site protections that detect and prevent any cell tower interference and its best-in-class warranty protects the product for three years.

Mimo for 4G LTE Routers and When You Need It (and When You Don’t)

(Multiple-Input Multiple-Output)

First, we need to start with a simple question. What is MiMo? MiMo stands for Multiple-Input Multiple Output, which is a wireless technology. For the purposes of this article we are going to talk about what MiMo is in related to cellular signal. With MiMo there are multiple transmitters and receivers on each side of a connection used to send and receive more data at the same time. 4G LTE cellular technology is built on MiMo, meaning the cell tower and end user device have multiple antennas on each side to help improve speeds and reliability. MiMo is also commonly referred to as diversity which is the same concept.

(Pepwave MAX BR1 - MiMo Cellular Antennas)

Embedded cellular routers from manufacturers like Cradlepoint , Pepwave , Sierra , Netcomm , and more, all take advantage of MiMo on their 4G LTE capable devices. There will be a cellular main and cellular aux antenna port which creates multiple paths to the cell tower. Most of these embedded cellular routers include small screw on antennas for cellular reception, but what do you do if you need to install the router somewhere where cellular signal isn’t reliable?

The common solutions are to either run an external antenna, use a direct connect amplifier, or install a cellular repeater system. We’ll look at each option and when MiMo does and does not benefit the embedded router.

(Panorama Enclosure Antenna - Use Two for MiMo!)

When running an external antenna only with no cellular amplifier, it is best to run 2 external antennas, or a single external antenna that supports MiMo (this would be a single antenna that has 2 leads to connect to the modem). This setup allows the embedded modem to retain its MiMo capabilities while still having an external antenna to maximize signal strength to the modem. Lets use the Pepwave MAX BR1 Mini as an example. This has a cellular main and cellular aux antenna port. If it was installed in an ATM machine it may have weak cellular signal due to the metal enclosure it is surrounded by. An external antenna is needed in this scenario.


(Panorama Panel Antenna - 1 Antenna with 2 Connectors)

Two Panorama Enclosure antennas can be connected to the BR1 and installed on the exterior of the ATM machine. You’ll get full MiMo performance which will allow for the best network speeds possible. If the MAX BR1 Mini was installed indoors, a building mount antenna would be needed. This is where a single antenna can be installed, such as the Panorama MiMo Panel antenna. This is a single antenna with two leads to connect to the two ports on the BR1. Installation is simplified with a single external antenna, but MiMo performance isn’t sacrificed. When using antennas only, it is best to have a MiMo configuration whenever possible.


(Cradlepoint IBR600 - Stock Antennas)

We'll look at another example using a Cradlepoint IBR600 router. This device also has two cellular antenna ports for MiMo operation. The stock antennas are simple paddle antennas, but again, mounting location plays a lot into the cellular signal strength. Sometimes a full fledged outdoor antenna isn't possible to install and a higher performing indoor antenna is needed.


(IBR600 with Indoor MiMo Antenna)

This Panorama Portable antenna includes a length of cable to help position the antenna indoors where the signal is best, while still maintaining MiMo performance on the Cradlepoint router. This is great for server racks, digital signs, kiosks, or anywhere else where a boost in signal is needed to get the maximum performance out of the router.


(Signal 4G Direct Connect Amplifier Kit)

The story changes when you start looking at cellular amplifiers. Direct connect cellular amplifiers are popular when cellular signal to a single device is weak and an antenna alone isn’t enough to do the job. The amplifier mounts near the embedded router you need to boost the signal to, and an antenna is connected to the amp. Amplifiers, aka signal boosters, dramatically improve the incoming and outgoing signal between a cell tower and device. By using a direct connect cellular amplifier, speed and reliability can be dramatically improved to a single device. Amplifiers do have a downside though, and that is along with the boost to cellular signal, they also boost noise. Signal to Noise Ratio, or SINR, can make or break cellular connections. Too much noise, regardless of how strong the signal is, and a modem won’t be able to connect! When using a direct connect cellular amplifier it is advisable to only use a SINGLE cellular amplifier on the MAIN antenna port of the embedded router, and disable the aux antenna port if possible or simply do not connect the second antenna. What happens to MiMo? Simply put, you no longer have MiMo performance in this configuration, but often times the addition of a second cellular amplifier does more harm than good due to excessive noise introduced to the modem. When a direct connect amplifier is required, the modem will typically perform better with a single amplifier and antenna instead of two. An amplifier like the Signal 4G is a popular option for a direct connect amplifier and can be used in M2M and IoT applications as well as for home or business use to provide the highest gain to a single device.


(weBoost Connect 4G Repeater)

Cellular repeater kits have the same restriction as direct connect amplifiers. With a cellular repeater there is an external antenna, amplifier, and internal antenna to rebroadcast the signal to multiple devices including the embedded router you want to boost the signal to. You can’t run two separate repeaters in a way where they can boost a main and aux connection on a router without the kits interfering and shutting each other down, and even if you could, there would be so much noise in the environment the amp may not connect. Again, you have to consider that if an amplifier is required the benefits of having a usable signal, even if not full MiMo performance, is better than no signal at all! The weBoost Connect 4G is a kit that can boost cellular coverage up to 5k square feet to multiple devices at the same time.

What about USB modems and hotspots? Unfortunately, most USB modems and hotspots do NOT have external antenna ports that support MiMo functionality. In our testing with one or two external antennas connected the devices perform exactly the same, which is an unfortunate limitation of consumer grade devices. Upgrading to an embedded cellular router provides an immediate reliability boost, and often times speeds are improved just by using the small included antennas that these devices include, and can be improved even more with a proper external antenna. Read more about USB vs. Embedded hardware.

Will an Antenna or Amplifier Help Me? Find out BEFORE You Buy!

How can you determine if an an external antenna or amplifier is needed? We recommend you start with a simple site survey that can be performed with an iOS or Android phone. By taking measurements of the signal both inside and outside the location your device will be used, you can determine the best device for the job. Need help interpreting your results?
