Wireless Systems Guide for ANTENNA SETUP ANTENNA DISTRIBUTION Antenna Height Receiver antennas should be clear of obstructions, Proper antenna distribution is key to achieving including human bodies, which can absorb RF. Therefore, optimum performance from multiple wireless systems placing the antennas higher than “crowd level” (5 or 6 feet, operating in the same environment. -
Page 8: Active Antenna Distribution (3 Or More Receivers)
Wireless Systems Guide for ANTENNA SETUP Active Antenna Distribution (3 or more receivers) If distribution is needed for more than two systems, an active antenna distribution system is recommended. Active splitters require power to operate, but provide make-up gain to compensate for the additional losses resulting from multiple splits off the same antennas. - Page 9 Wireless Systems Guide for ANTENNA SETUP Coaxial antenna cable loss at VHF and UHF frequencies Antenna amplifiers per 100 ft (30 m). Use this value to calculate the expected loss at the receiver for the desired cable run. A loss of...
