Circularly Polarized Antenna for the UHF Band 03.2006

The A 5000-CP antenna has RF performance characteristics that are extremely

desirable for usage in the UHF broadcast band, both as transmit and receive

device. Actual installations have demonstrated that the circular polarization of

this antenna minimizes variations in signal strength and almost completely

eliminates multipath problems, a primary cause of ‘hits’ or nulls. The gain of this

antenna over the entire UHF band is superior to the common ‘off the shelf’ an-

tennas. The A 5000-CP’s extreme broadband capability provides the freedom to

utilize just one antenna model anywhere in the UHF spectrum. Because of its

unique 3 dimensional radiation pattern, the antenna can be mounted above the

talent or venue, oriented with the antenna element facing down. With the main

lobe (maximum gain) of the antenna pointing downward to the desired source,

this arrangement has the advantage of greatly reduced sensitivity for potentially

interfering signals arriving horizontally.
