10-PORT ANTENNA COUPLER ROHDE & SCHWARZ NV 14T
US $65.20 (Reserve not met)
10 port multicoupler made by Rohde & Schwarz,Munchen , Germany. With this device, you can connect up to 10 receivers to the same antenna in the range 1-30 MHz ( down to 10 Khz with a simple mod.) The coupler is an active device,but does not exhibit gain, simply has no losses and constant impedance of 50 Ohm regardless how many receivers are connected. The performance is astonishing, I've used it for a long time with general coverage antennas, ( long wires) and I've never noticed intermodulations The unit is complete of ac power supply and cabinet, and is perfectly working. In my archive I have also copy of the manual,complete of schemathics, but the use is obvious and intuitive. This is a professional device offered at a price affordable by the radio enthusiast! ONLY FOR RECEPTION, NOT FOR TRANSMISSION
