I would think the W2DU style would be the lightest but also pretty
ineffective on 160 as well as power limited.
Use a heavier duty rope (or #12 solid Copperweld , non resonant lengths of
course for all bands), and a couple of Fair-Rite 2631803802 31 mix 2.4"
toroids. Use RG-400, to wrap the toroids and then LMR-400 or similar if
running 1500W. RG-8X will handle 1500W on 160 but its a bit marginal
especially when the VSWR climbs or when you decide to try digital or RTTY.

Subject: Topband: 160 ground plane choke
I've been using a 160 GP with 4 radials. It's a Tee-top supported with a
rope between two towers, with the top around 165 feet and the base at 70
feet. I'm feeding it with RG8X to keep the weight down on the rope which
supports it.
Although it works well I would like to negate any loading which might be
taking place on the feed line which drops from straight down from the
base.
Any ideas for a cheap, easily made, effective choke on the feedline?
