If antennas are remote-mounted, separating them 6 feet (1.8m) or more and keeping them at least 2 feet (.6m) from other barriers will improve performance (see Figure 8). If you are remote mounting the antennas and require strong signal over a large area, consider using highly directional antennas such as a log-periodic. The ALP-450 available from Telex is tuned for frequencies from 450-900 MHz and can provide an additional 5 dB of gain.
3.If you remote-mount the antennas, attention should be paid to the type and quality of the antenna cable. For cable runs longer than 25-ft. (7.6m), special low-loss cables should be used.

4.If multiple wireless systems are being used, a multi-coupler will minimize antenna interference. A multi-coupler has one set of an- tennas and distributes RF signal to multiple systems. The Telex will supply antenna signal and DC power to 4 systems, eliminat- ing 3 external power supplies and 6 antennas.
