[TowerTalk] HyGain 86 Vs BN 4000

[Dennis W0JX via TowerTalk]

Don,
The BN 86 is prone to arcing to the ferrite rod especially if the SWR is high and you run power.  The BN4000 is essentially a short piece of small diameter teflon coax with ferrite beads around it jammed into the same case and filled with a hard as nails epoxy.

The problem with the BN4000 is that after years exposed to cold and hat, the case cracks. The epoxy filler also expands, and in case, the center conductor pulled away from the coax connector. It was quite a job to cut it open and chip away at the epoxy and fix the connection. You did the right thing bu going to the Balun Designs unit.
