The QUADBox multicoupler provides a convenient, highly portable mechanical assembly with integral RF and power distribution for up to four receivers. Two different multicouplers are available to configure the system for either the UCR190 UHF receivers or the CR187 VHF receivers.
The signal from a single antenna is filtered, amplified and distributed to the four receivers through a high performance RF multicoupler. The RF distribution module is a high performance design that applies filtering before gain is applied to the signal. The gain applied to the signal is just enough to compensate for the required loss in the splitter to preserve the excellent RF performance of the receivers. A 2-pole ceramic resonator is
used ahead of the RF amplifier to reject energy above and below the passband. The RF amplifier is a high current type with a high overload threshold to minimize intermodulation.
