That is good news about Rohn. They have always made a quality product.
The 25 series had the fold over option, of course, but the HB series could
be cranked over. One would have to have a support pole with a winch and it
hinged on two of the legs to lower it. The lowering was horizontal not
I had my set up this way and it worked just fine. The legs were fitted with
thick walled pipe and one removed the bolts on one of the legs, then one of
the bolts on the other two legs. With proper cable and a winch, you could
lower the tower.
I hope to have mine back in operation soon. I have a Mosley TA-53M on top
with a Hygain 400 rotor. The rotor plate was, of course, and option and
bottom mounted. They had that plate back when the rotor was manufactured by
Hygain. Sure has been through a lot of storms and both have survived. I
have the HBDX 40 and would like to add the next section, but that would
require changing the leg supports and saddles for the fold over.
If I remember right, the 25 series catalog recommended only about 25 ft.
above a house bracketed with about 6-8 sq. ft. of antenna maximum, but that
is poor memory talking. As Brian mentioned they can be loaded much more
than that and survive.
Glad they are back.
