Does that mean that you're going with straight guying and no
Union County, NJ, is an 85 MPH wind speed zone so I would suggest using
the 90 MPH Rohn specs for your project.

This is a small load so just about anything will handle it. I think
you'll find that it won't be too long before you want to put up something
different/bigger. A Ham IV or Yaesu 450 or even an Alliance HD-73 will work.
Used, refurbished rotators are available from The Rotor Doctor
(www.rotordoc.com) and Norm's Rotor Service

Congratulations! You'll have a ball now that conditions are picking up.
If you need the Rohn Catalog, they're five bucks from TOWER TECH, Box
572, Woodinville, WA, 98072. It's got all the specs in it.
