[TenTec] Information about chokes needed

[JAMES HANLON]

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
