> I currently have a Rohn HDBX 48' tower. While the tower has a pretty
good wind load rating, 18 sq ft at 3' above the tower, Rohn limits the
boom length to 10'.
> I would like to put up a 2 element 40m beam as well as a 3 or 4 element
10/15/20 meter beam with a VHF/UHF vertical on top. Wind load wise this
may not exceed the load rating of the HDBX, but I'm pretty sure it
wouldn't be recommended as boom lengths are a lot more than 10'.

HDBX
that could handle such a configuration? With all the concrete in the
ground, I'd like to use it.
Howdy --
Are you W0RK? There wasn't any callsign in your email. If so you're
listed as being in Stearns County, MN - an 80 MPH windspeed zone. You'd be
really pushing your luck with the proposed antenna array. The BX et al. are
towers for TV antennas. They're light- to medium-duty depending on the
configuration. The sections are held together by aluminum rivets so they won't
take much stress - that's why there's the 10' boom length warning. Consider
yourself warned.
Sell it and get a real tower. Or keep your homeowner's insurance paid
up for when the catastrophe happens.
