Important Aspects to Look at When Choosing a Military Antenna
Are you looking for military antennas? Buying a military antenna comes with several considerations to make sure that it suits your application. Here are some of the pointers that you should consider when purchasing a military antenna.
First, make sure that you have considered the frequency before selecting a military antenna. The bandwidth/ frequency range of an antenna usually shows the range of frequencies over which the antenna has been designed to have an optimum VSWR. If you want a wide bandwidth, then make sure that you have selected an antenna with a narrowband. However, you need to make sure that the antenna is suited to meet the specifications and the applications you have. With this, you are assured of choosing an antenna with a good match VSWR and one that has an improved beam pattern.
The other important thing that you should consider when purchasing a military antenna is the power rating. You should know that the power rating is the maximum RF power that is applied to the antenna without causing damage. You need to know that receiving antennas usually receive low RF power and for this reason, the power rating is only crucial for transmitting antennas where higher powers are used to make sure that observable signals are received by the receiving antenna after larger distances have been traversed. Applying high power than what the antenna has been rated for could cause damage.
You also need to make sure that you have considered the beam pattern before choosing the right military antenna. While sometimes an antenna can appear to function perfectly with low VSWR over the frequency range of interest, you need to know that the antenna might be concentrating its power in an inappropriate direction. Based on the applications for the antennas you want, you might be required to make use of an antenna with an omnidirectional beam pattern, where the antenna is ideally good in all directions. You might also be required to utilize a directional antenna, where the antenna’s operation is focused in one direction. It’s important to keep in mind that the beam pattern of an antenna is also frequency dependent. As such, you need to ensure that you are extra careful when selecting an antenna to ensure that you are picking an ideal option that will operate at all frequencies to meet your specific needs.
The other key thing that you should keep in mind before choosing a military antenna is polarization. You need to know that the polarization of an antenna explains the direction of the electrical field vector of the electromagnetic waves that are being transmitted. There are different types of polarization used. These include vertical polarization, horizontal polarization, Right Hand Circular Polarization (RHCP), and Left Hand Circular Polarization (LHCP). It’s important to ensure that you have considered choosing the polarization that suits the signals of your preferred antennas so that you can prevent potential signal loss
In winding up, make sure that you have purchased your military antenna from an experienced and reputable antenna design and manufacturing company!
