If antennas are remote-mounted, separating them 6 feet (1.8m) or
more andkeeping themat 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. Amulti-coupler has oneset 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.
