Before WX0B switched to use feed through insulators I replaced two of his baluns on Optibeams at a friend. Baluns were made from RG393 wound through ferrite toroids. Around the stainless steel screws

Jim & Steve, I'm not sure I follow... I have made some baluns recently with the 4 nut scheme that Jim is describing. Are you saying it is problematic or not? Thanks and 73, Gary kk0sd Or 4 nuts - nut

Martin makes them, McMaster no brand was by them a while back. Also sometimes call tappet wrenches. Hard to find in < 7/16" but most ignition sets are thin enough. Amazon has Craftsman and assorted C

It would be wise to use an oversized flat washer over the screw on the inside of the plastic box before the lock washer and nut. N9AU nut scheme that Jim is describing. Are you saying it is problemat
My strategy is no coax connectors out on a boom. Feedpoint ferrite chokes are in a PVC junction box with coax in thru a watertight gland and two glands out for short #10 leads to the feedpoint. So no

Balun Designs recommends and sometimes puts weep holes on the bottom of their balun boxes. I had some cable junctions in an 8" 'waterproof' electric PVC box. I traced a failure of the connections in
That reminds me, the Myantenna line isolator I just installed had a tiny weep hole on one end. It would have been awfully easy to install upside down. 73, Pete N4ZR Check out the Reverse Beacon Netw
