Sennheiser A 5000-CP manual Technical Data, 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.
