We use the K9AY Model RAS-8x2 Receive Antenna Switching System
So do I. I had him build me an 8x4 version. Six RX antennas feed the matrix, plus the output of an NCC-1. Two of the outputs feed the NCC-1, the out of the NCC-1 feeds input #7, RX out of my primary K3 feeds input #8.
The other two outputs feed RX In and Sub RX in of both K3s. This setup provides lots of flexibility -- I can phase anything with anything. During 6M season, a GAs-FET preamp gets patched between RX out and the matrix. It's slightly better than what's in the K3.
