[Towertalk] Re HyGain Balun

[Fred Hopengarten]

I have two HyGain TH6DXX and two HyGain TH7DX antennas in the air. I made
up little plastic boxes from Radio Shack, mounted SO-239's and stainless
steel studs (1/4-20 bolt and nuts) wired it to be the equivalent of
splaying the coax (I was worried that it is hard to pevent water from
getting into the coax and I preferred the ease of a PL-259/SO-239 when up
in the air). Each coax has 6-7 toroid beads on the RG-213. Remember to
put on the beads before the PL-259 (I own that T-shirt), or pay more for
split beads (cheaper than re-doing the PL-259's, if you value your time).


I have removed the BN-86's from service.
