Wireless: Can I setup a Tempest base station in a rack and successfully remote the antennas to the top of the rack?
Question: I'm installing a Tempest 2400 base station in a rack at the FOH position in a auditorium and I would like to know if I can remotely place the two antennas at the top of the rack in order for the beltpack users to have better Line Of Site (LOS) coverage in the auditorium?
Answer: Yes, in order to maximize the range of the system and provide the beltpack users better LOS coverage with the base station the two whip antennas should be relocated to the top of the rack (see the diagram below). Install the Base Station in an equipment rack (1 RU) and use two optional LMR-195, 50 ohm coax in lengths up to 10 ft to mount the antennas above the equipment rack. (5 ft of LMR-195 coax induces about 1 dB of attenuation at 2.4GHz).
To remotely locate antennas, always use high quality, low loss, 50 ohm RF cable terminated with an RP-TNC connector for the Base Station side connection and the appropriate antenna mating connector on the other end. LMR-195 (or equivalent) coaxial cables can satisfactorily be used in lengths up to 10 feet. LMR-400 coaxial cables (or equivalent) can be used at lengths up to 25 feet. Longer RF coaxial cable runs are not recommended due to signal attenuation in the cable.
