I would only comment that any lightning protection must be done outside of
the structure. You do not want to provide a path for lightning to enter the
house and then be dissipated. This includes static build up from wind or
snow blowing thus inducing static electricity on the antenna.

If you are using a balanced tuner that makes a DC connection between both
sides of the ladder line and the tuner coil, just center-tap the coil and
ground the center tap. If you are using some other kind of tuner, look
for a point that makes DC connection to the feedline and that can be
grounded without disturbing the RF function.

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
