And another approach is a "spark gap" method. These are sold by The
Original Wireman.

Or you can make your own with a couple of small engine spark plugs, a metal
plate and miscellaneous hardware. That's what I did and it does the job
nicely. I tried the carbon resistor approach as some have suggested and
found that they fail rapidly with weather and RF.
As with all lightning protection systems, they should be located entirely
outside of the structure.

Subject: [TenTec] Information about chokes needed
Hello Folks i realize this is not a TenTec question and i am sorry about
that. Allthough i am a very proud Red dot owner. Any how here is my
question. I am preparing as we speak a doublet antenna and my first using
ladder line. I want to be able to drain stactic off the ladder line. I have
read many places RF Chokes work for this.
Being a Home brewer kind guy when i can be a want to wind my own, But i can
not find any good info on the project that tells the specific information as
to how many winds how how big a form etc etc, I asked this questio once on
another forum, got a bunch nonsesne. So i came here where the real Pro's
are. all replies will be most welcomed.
Oh and i need this for max 1500 watt power levels. Many thanks Jeff
