Modular 7ANT RX switch with controller, up to 3 RX and REMOTE control

This is modular 7 RX antenna switch. It allows you to use up to 7 independent RX antennas (beverages, Bi-dir beverages, RX loops etc.) to one, two or three RX (TRX). You can use just one board for single RX output or up to three boards for three independant RX. ALL outputs are wide-band, there is NO BPF in the way between ANT port and output. Also ANT ports could be open or connected to the 50 or 75 ohms dummy loads. Dummy loads could be isolated by simply LC BPF isolation. This is there for M/M setup with middle splitter box. You can use controller with BPFs and preamp. Front-end protections are built-in as well as RX way switching. You are able to share any antenna to any RX at different bands or different antennas at the same band at all outputs.

This is ideal solution for Single OP through SO2R to Multi-Multi, with up to 2 (3) independent RX per band!
