Antennas
The receiver antenna may be the most important single component in a wireless- microphone system. However, this is the item most often overlooked in setting up a system, and is frequently the cause of quite unnecessary problems. Proper placement of the receiving antenna(s) is vitally important in any wireless-microphone system.
A whip antenna connected directly to the wireless receiver is adequate for many installations. This type of antenna is provided with the R-662 Series receivers. When the distance between the receiver and the transmitter is 100 to 200 feet (30-60 m) or less, and there is a clear, unobstructed line-of-sight path between the receiver and the transmitter, good results can usually be obtained.
Optional Antennas
If you wish to have the receiver in a location which does not have a clear line-of- sight path to the transmitter, another type of antenna will be needed. Vega offers magnet-mount 1/4-wave-whip and “ground-plane” antennas with an attached 15- foot (4.6-m) cable, which may be used for this purpose. Two such antennas are required for use with diversity receivers.
Other types of antennas may be needed for unusual applications, such as operating at extreme ranges of 500 feet (150 m) or more. Vega offers a high-gain log-periodic antenna that covers the complete operating-frequency range of the R-662 receiver. UHF TV antennas (with appropriate matching transformers) are often used for this purpose. A wide-bandwidth “corner reflector” antenna works well in this application.
