[Amps] Triband balun

[Jim Smith]

If you want to make a balun by coiling up a bunch of coax you should 
check this out first.  Removes all the anecdotal BS and gives you 
something real to work with.

When I replaced my TH3 balun I used a DX Engineering current choke, 
including the appropriate clamps for attaching it to the boom.  Been 
using the TH3 since 1967.  Only recently got an amp, though, which is 
when the balun failed.


Roger,

I had a look for the connectors you mentioned.  It isn't clear to me 
which ones would be appropriate for the Ham M.  Do they mount in place 
of the terminal board or do they just hang from wires dangling from the 
rotator?
