Hi Bruce,

I am a tad confused by your reasoning, so please excuse me...!

Are you implying that "some" amount of voltage build-up is OK somehow? I don't get the logic in that---to me, it's all or nothing. What's to be gained by having less voltage to bleed off, s. more? An RF choke to ground doesn't care if it's a lot, or a little: it just does its job, end of story...

I'm no expert by any means, but please enlighten me as I think I've obviously missed something.

Thanks!

PS: FWIW, I always endeavour here to use insulated wire in ALL of my antenna projects---even radials laid atop the ground. I guess in the case of wire up in the air, I still subscribe to the belief (urban myth...?) that rain & snow discharge themselves on bare wire, "static electrically speaking". For the minimal extra expense of insulated vs. bare wire, it's one less thing that I have to worry about, rightly or wrongly! Hi Hi
