A used Tri-Ex LM-354HD. Will handle your windloading with ease, goes to 54
feet plus a HD mast will take it to 60+ feet. Motor crank up if you can
find it. I would consider a prop pitch instead of the Prosistel. Pro
sistels don't have the greatest reputation and are expensive, whereas a prop
pitch with a Green Heron control box is virtually trouble free and more
flexible. I now have a LM34HD and it is rated at something like 52 sqft at
87mph. I have also run with the LM470, which is the same tower with an
added top section, using a prop pitch to rotate a KLM Big Stick 6 element
20M beam on a 58 foot boom. Had it up in CA for 6 years and never had a
problem with anything.
