I've used automobile scissors jacks (old GM and Datsun/Nissan ones, for example) to realign the ends of Rohn 25 and 45 sections. "Buffer" the jack-leg interface with short pieces of 2 x 4. I've done

Adding a garage door spring of the appropriate stiffness at one end of my 80-meter dipole seems to help protect the dipole from the effects of its support branches whipping around in the wind. The us

I agree with Steve -- at least for reasonable guy wire angles. Consider the case of horizontal guy wires. With horizontal guy wires, high winds add no downward force on the tower legs; the only downw

I've used a garage door spring on my 80-meter dipole for about a decade now. Seems to do a good job, although I have plain old #10 copper wire so it's possible I now have a 90-meter dipole.... My loc

There's one other way Rohn 25 and 45 differ from each other: They're different lengths. Each standard Rohn 25 section is a total of 10' 0" end to end, so when you build a tower, the tower height is N

Absolutely NOT! Rohn (ca. 1987) allowed ordinary Rohn 25 to go to 40 feet unguyed only if the antenna load was under 1.5 square feet and the wind speed 70 mph or less, with no ice. For 90 mph, Rohn d
