In general, the best location for antenna placement is always the closest to the transmitter. The type of antenna selected also has an effect on placement as discussed earlier. Since the transmitted signal is typically vertically polarized, it is important to orient the receiver antennas in a vertical position. The best place is usually on an adjacent wall, near the vicinity of the transmitter, using the frequency length formula to determine the proper distance between the antennas. When a number of multiple systems are used in a given location it is a common practice to use antenna combiners to eliminate the antenna Farm. Antenna amplifier/combiners are a convenience item that allows a single pair of antennas to feed multiple receivers
