The Tail Twister manual recommends #16 ga minimum up to 100 feet, and #14 for longer runs, and I've found that advice to be very wise.

(score: 1): Author: stevek@jmr.com (Steve Katz); Date: Tue, 6 Aug 2002 07:07:55 -0700; Have to admit the below is a "brute force" solution that can be a bit expensive and a bit of work, but I have also pretty much given up on Tail Twisters. Powerful, yes. Good design, no. My next "big; /archives//html/Towertalk/2002-08/msg00128.html (12,719 bytes)

It's also a bit longer and has a separate, dedicated 10m reflector element not found on the TH3.
