Bill,
I had varying swr on 160M. I shunt feed my tower. I added a strap from the
mast to the tower leg. SWR settled down. Using a TB3.

Subject: [TowerTalk] Which thruse bearing?
I've had towers for years but never used a thrust bearing. Now I want
to. In comparing the Rohn TB-3 and the Yaesu GS-065 I see the Rohn
sells for about three times the price. Is it three times better?
This may sound odd, but the reason I want a thrust bearing is to
provide a lightning path directly from mast to tower rather than
having the strike go through the rotator to the tower. In other words,
I want to use the thrust bearing to ground the mast as opposed to
having the mast free-floating. Does that make sense?
All comments welcome.
Bill, W6WRT
