The Physics Of Military Antenna Mast

By Tammie Caldwell

Military operations are very critical and those in the base need to know the whereabouts of the other men in the field. Hence, communication systems are very helpful in such critical situations, especially in asking for backups when the situation gets out of hand. When it comes to military communication systems, radio and antenna devices are the most reliable. There are light antennas but they do not guarantee high frequency signals. Most of the time, size and weight are the primary issues with military antennas.

Some of the most reliable systems in military operations are RF and Satellite Communications. The use of military antenna mast is crucial for both. But there are things to consider in manufacturing these innovations, like the bandwidth, size, and materials. The cost of manufacture and labor are also included. Hence, it is never easy to modify or improve antennas.

The RF antenna is very common but users tend to complain on how heavy and big they are. They are often inconvenient to bring in battle areas because the men still have to bring heavy loads of bullets, ammunitions, and firearms. Hence, manufacturers and designers are having a dilemma regarding how they can actually resize it into smaller versions, as requested.

Some of the most efficiently working systems are those that have antennas even taller than a man. These are very inconvenient to bring especially in battlegrounds where the men will be running around and using their heavy armors. The taller they are, the better they will be able to receive radio signals.

Unfortunately, there is still no known device and innovation of antennas that are handier and least heavy. If there already are, it would be much easier for the army to carry them while on the battlefield or wherever they may be assigned. But the professionals are on their way as they are continuously finding ways to make this possible.

A given option is to use the cell phone in military operations instead of radio. Signal wires are already mounted in the cell phone so it should be a lot lighter to bring. However, the concern of the experts is that these devices are more susceptible to frequency interferences.

There is a need to modify first the structure of the cell phones to make its signals reach extensive distances. Phones normally need ground based signals to function more effectively. Most war zones have very limited or no access at all because of very few or even absence of infrastructures for phone networks.

Phones are prone to interferences in radio and signal. And if there are interferences, it is very difficult to reach the other side of the line, which in military operations, is the base. Moreover, if the base is not reached, they will not be able to report injured men in the battle.

Also, satellite communications are very efficient. These can be used in information dissemination quicker and more efficiently. These are the ones being used by armies to report the locations of enemies using communication codes.
