The Beyerdynamic passive <b>WA-ZAPD1</b> two-way combiner is used for multi-antenna systems in conjunction with wireless systems such as the beyerdynamic TG 1000. It can directly be connected to the TG 1000 receiver. In order to avoid unwanted dropouts inside the combiner, it is necessary to make sure that both antenna signals have the same field strength.</p><p>As the antenna phantom powering of 8-9 V is routed from the TG 1000 receiver through the WA-ZAPD1 combiner, the WA-ATDA antenna or the WA-AMP antenna amplifier can be operated with the combiner. The antenna or antenna amplifier is connected via BNC sockets.</p>
