FAQs

What are typical gain characteristics for omnidirectional antennas?

For omnidirectional antennas, general guidance indicates gains are typically about 0 to 2 dBi within 20 degrees above and below the horizon for antennas of standard dimensions like a half-wavelength dipole. The reviewed product data lists a gain of 0-2 dBi, aligning with this characteristic. (Source IDs: src-75fee6bf4644d22b)

What factors should be considered when selecting an omnidirectional antenna?

General guidance for selecting an omnidirectional antenna involves several key questions. These include determining if the antenna is for receive-only or transmitting (and at what power levels), the specific platform it will mount to (e.g., handheld, manpack, vehicle, fixed site, portable), the frequency of operation, the maximum continuous power the transmitter will output, and the maximum VSWR the transmitter can tolerate.

How does the radiation pattern of an omnidirectional antenna like a dipole typically behave?

General guidance suggests that the radiation pattern describes how an antenna radiates or receives energy and is critical for covering the intended area. For a linearly polarized antenna with dipole-like characteristics and vertical polarization, there are typically nulls to the zenith and nadir, with maximum gain occurring on bore, perpendicular to the antenna face, at the horizon.

What distinguishes dipoles in tactical communication systems?

In general, tactical communication systems often utilize dipoles for fixed site and portable applications. The choice between a dipole or monopole depends on the concept of operations, co-siting with other antennas, and the platform's ability to provide a suitable counterpoise.
