Antennas for Cellular routers

An antenna can help increase the quality of the cellular signal received by a cellular router. Better signal leads to fewer disconnections and faster download speeds. Here is a guide of things to consider when buying a cellular antenna.

What Antenna Should I Buy?

Omni-Directional Antenna Or Directional Antenna

When choosing an external 4G or 5G antenna, the two most popular options are Omni-directional and directional antennas. An omnidirectional antenna is best suited for urban areas or where there are multiple towers. The reason for this is because an omnidirectional antenna will collect cellular signals from all sides and can help increase the network signal for you.

This also means that you will not necessarily need to align your antenna to some angle for the best signal. This kind of arrangement is the best in a mostly urban location that has network signal issues. You might face some gain issues with an omnidirectional antenna, but as it will be located within a place receiving signals from many sides, the net gain will not be too bad. 

A directional antenna is designed up to receive signals from one direction (the direction of the nearest mobile tower). These antennas work great when there is a clear line of sight with no obstructions from the antenna to the cellular tower. The gain is exemplary and can help enhance a weak or intermittent signal. 

Similarly, Trimble GPS antennas are a perfect choice for optimal network synchronization and precise location tracking. 

Choosing Your Antenna Mode

If you are looking forward to increasing the signal range in your home, business, retail store, or any other stationary place, a fixed antenna will be perfect. Ideally, the antenna is fixed to the roof of the building or set near a window to get the best possible connection for a static space.

On the other hand, if you are going to maintain a cellular connection while you travel, a mobile antenna can be installed in RV, trucks, cars, busses, or a train. Mobile antennas are designed to pick up signals while moving at a significant speed and lets you stay connected without interruption. 

Single or Multiple Inputs, Multiple Outputs (MIMO)?

To get the best quality signal and speed from a 4G or 5G device, multiple antennas are required. To use multiple antennas with one device, you require a MIMO device. Just as it sounds, a MIMO device will have connection points for multiple antennas (inputs0> multiple inputs or antennas to connect. So, if you are planning to increase your LTE or 5G network speed, you will require at least two antennas for the maximum gain.

High Performance or Single-Cell Enhancement

An external antenna can help you in more than a few ways. You can go for a complete high-performance plan and buy an external antenna that helps create a bubble of high network signal around the building you are using. Using this antenna type helps businesses, organizations, or for houses in remote, unconnected places. 

On the other hand, you can buy an external antenna for your cellular network enhancement. Using this can work as you go traveling, hiking, or cruising in remote places, or need to send signals in disaster emergencies, etc.

Picking The Length Of Your External Antenna Cable

In cases where the antenna has placed some distance from the device, the length of the cable connecting the antenna to the device is a concern. Generally, cables that are 10 feet long or less are Ideal. Cables longer than 10 feet will result in poorer signal quality that gets worse as the cable gets longer. To avoid using a long cable mount the cellular device closer to the antenna, or, move the antenna to a higher location that has a clear sightline to a cellular tower.


A shorter cable does not necessarily translate to a better 4G or 5G signal, but it does increase your chances at better network connectivity.
