Remote Antennas
In fixed installations such as A/V or corporate conference rooms or for extended range
applications (where the transmitters and receivers are more than 150 feet apart). Placement
of remote antennas is critical, with the most important factor being the need to get them near
the action. The antennas should be placed within line-of-sight of the performers, so that the
performer can see the antenna. When using remote antennas, it is recommended to use 50 ohm
coaxial cable that is suitable for up to 1GHz bandwidth usage (such as RG-6 cable). If you plan
to run cables longer than 100', you may need to use an in-line RF amplifier.
