Looks like the gas discharge type I have.
Somewhere I heard someone say that they go shorted when hit,
like a MOV, but that seems counterintuitive and it seems more likely
that they would just go permanently open by out gassing.
What's your opinion on this?


My DX-Ultra has a proprietary gas discharge arc-plug in its core.
Alpha Delta says that after several years of significant static, it
can get weak and the antenna won't function as well. Just to be anal,
I put in a new one about 6 years ago, and it's worked about the same
before and after and ever since.
