Just make sure the RG-214 is silver-plated. I had a jumper I used this weekend for a 2 meter repeater installation that said "Intercomp RG-214" that caused desense when I flexed it, so I replaced it. When I got home I took a close look at one of the connectors & could make out a couple of COPPER braid strands. That jumper got the colored tape band applied to the middle, my indicator that it's "no good for duplex". Bob NO6B
