I posted similarly a couple weeks ago and got some good advice from the reflector.
It's come down to the JK Mid-Tri/40 and the Optibeam OB12-4W.
The JK is 40/20/15/10m, the Optibeam is 40/20/17/15.
The JK is less expensive, somehow a bigger windload, and built like a tank. It has no WARC bands.
The Optibeam is more expensive, smaller windload (by about 5 sqft, not sure how), built just as well as the JK and has 17m. I won't be caring too much about 12 and 10 meters for a while. When the spots come back I'd need to get a 17/12m beam for the JK or a 12 and 10m beam for the Optibeam.
Either beam will be at 70-75 feet on an AN Wireless HD70 tower and 3" x .25 wall CMoly mast, Plans are to top things off at 90 feet with an JK 80 meter dipole. When I started this, the plan was the Mid-Tri minus 40m, WARC band beam half way up and an 402T at 90 feet. VE7RF advised I should consider the 40M Mid-Tri and the 80m dipole. I have never had an 80m dipole that high much less rotate it. It's always been very short verticals or very low dipoles.
Since I have never been on 6m I may stick a 6m Beam between them at 80 feet and see what happens.
Rotator is going to be a SPID Big Rak.

Subject: [TowerTalk] Need recommendations for a 40-10m. Yagi
I'm looking to purchase a 40-10m. Yagi this summer. It will be mounted on a 120' Self-Supporting Pi-Rod Tower in Wisconsin. I'd prefer the antenna to cover the WARC bands but it's not imperative as I'm a contester first and a DX'er second. Gain and reliability are my two greatest needs.
Note: I currently have a 3-element SteppIR at 50' so I do have WARC band capability for 17 & 12m. I'd love for my Yagi at 120' to cover 30m. but it's not a requirement.
A couple of questions:
1) If you were purchasing a 40-10m. Yagi this summer please advise which one you'd purchase and why?
2) The antenna is probably going to have a windload between 15-20 sq. ft. Please advise which rotor you'd purchase for it?
Thanks & 73,
