Gene,
I currently have a 56 foot version of that tower with a KT34XA two feet
above it. I CANNOT recommend this combination. My tower is somewhat
protected from the wind by high trees and terrain. But an A3S on the
48 foot version should be no problem. As far as the rivets coming out
I have never had one come loose. The KT34XA has been up there for
about 9 months and before that there was a Cushcraft 4 element 15
meter beam with a 20 foot boom for about 4 years. There are no guys,
but I plan to put up a couple in case of a freak wind storm.
Climbing the tower requires hard soled shoes and of course you stand on
the cross braces. Also use gloves as the hand holds all have right
angle edges. I realize I am far exceeding Rohns' ratings on the tower
with the KT34XA at 56 feet, but I think this shows that your A3S at 48
plus a couple of feet should be no problem.

Who out there has information or an opinion on
the Rohn series HDBX-48. This is a 48' self
supporting tower. I am considering putting
up this tower at my QTH in Medina, OH (Medina
County). I'll be putting a Cushcraft A3S or
equivalent beam on top of it. I know this
is not recommended by Rohn because they say
not to use anything with a boom longer that
10'. The A3S has a boom of 14'. I might
guy the tower, somewhat weekly with the guy
anchors about 10' from the tower just for
a little extra support. My main concern is
the Rohn manual for the HDBX says to replace
any loose rivets with bolts. WHAT? You mean
to tell my the x-braced rivets might come out?
I assume this means an annual trip up the tower
to check out all the rivets, carrying a cordless
drill and pocket full of nuts and bolts. How
does one climb this tower with the X braces?
