>I will be ordering a C-31XR soon. > >In the data sheets on Page 11, it says "All that is needed is a 1:1 balun >(like the Force 12 B-1) or RF Choke". Has anyone used >an RF choke in place of the Force -12 B-1 Balun with FORCE 12 antennas? Yes definitely -- I used one on the 40m element of my C-4, though I switched back to the B-1 when I converted to an EF-240S. The B-1 is a pretty good piece of equipment for $30 or thereabouts. Reason for changing was purely mechanical. > >I have been making my own RF Chokes for monobanders for many >years, using Coax.

Agreed, although it's been documented on Towertalk that the usual "bundle of coax" isn't much use -- it needs to be flat-wound, with the number of turns depending on frequency. 73, Pete N4ZR Contesting is!
