You can use a separate control wire from your operating position. From Figure 8, the five feed positions in the middle have gain reductions over a single feed of 0 dB to 0. Learn this aspect of electronics online because a good understanding of what happens after a signal leaves a transmitter and before it enters the recever itself is essential for anyone involved in radio or wireless technology. The VHF path (between the VHF and common ports) provides low IL at VHF and high isolation to the UHF port. A preamplifier is used to compensate for signal loss from a long cable run. If the only thing on your roof is a TV aerial then a diplexer plate won't give you an FM signal for the tuner. Product Description. TV Antenna design, UHF + VHF?
