Subject: [PVRC] Mounting a Remote Antenna Switch?
I have an Ameritron RCS-8V I'd like to mount, along with lightning arrestors, inside a weatherproof box that will go on the exterior wall of my house (I don't have a tower, but do have a number of wire antennas).
1. Can I mount the RCS-8V with the relays facing out and not down, as one would if it was mounted on a tower or mast?
[AD3F] Yes, I did that with my own COMTEK RCB-5 switch inside a Hoffman enclosure at the base of my tower in 2001 and I can still select whichever antenna I need. No misoperation of the relays.
2. Can I use CAT5 cable for the control line? It is 4 pairs of small gauge cable, and the switch wants 5 conductors.
[AD3F] Again yes. I use Cat 5 wire for my switch box which is fifty feet from my shack. If you had a much longer run (say, several hundred feet) Cat 5 might drop too much voltage to pull in the relays, depending on the source DC voltage inside your shack.
