[Repeater-Builder] Coaxial relay information

2005-01-29 Thread gm7svk
I have a couple of old relays made by AMPHENOL. They are marked with the code CT 42225 on the outer casing and have the code 316-10744-3 on the internal changeover switch/coax sockets which are N type. They will switch on 12V but are marked as 26VDC. Looking for rating RF information please.
