Default Help identify tower manufacturer

Gentlemen,

I am attempting to identify the tower manufacture of the tower pictured at:
http://www.ppinyot.com/antenna.htm. I would like to properly design a
base for it given the manufacturers specs plus perhaps pick up additional
sections.

The tower seems to be of a stamped steel design (not tubular) with stamped
steel cross members. It has been well maintained by the silent key's son.
I gather it is about 10 to 15 years old. There is an unpainted ladder
chained to one side for storage. Please do not confuse this as part of the
tower.

Also if you happen to recognize the beam please Identify it too.

Unfortunately some one discarded all the paper work not knowing it's value.

Thanks Paul

Paul:

It looks a lot like the one I have (except mine is still in the standard
galvanized steel, not painted red).
Mine is a Rohn HBX, though what is there could be a BX, depending upon the
sections used at the top.
It was generally available up to 64' in the BX version, and 56' in the HBX
version. The big difference is the top section is smaller on the BX version.
Each section is 8 feet tall, and the standard footing

http://www.antennasystems.com/towers.html#BXTOWER

has some information about the tower. I have a printed copy of the manual
somewhere, but it would take months to find it, as I'm in the process of
building a new QTH.. I had also found a copy on the internet somewhere, but it
was lost during a hard disk crash, but I imagine you could search for the
manual given the model number.

The base in the pictures is a tilt-over mount for the tower. I used the
standard (non tilting) mount, and it served me well with a large Cushcraft X-9
beam on it, plus a 2 meter 11 element beam above that, and several wire
antennas off in odd directions. It will be going back up at the new QTH. It
is the 48 foot HBX version.

Because it is in 8 foot sections, you can take it down or put it up a section
at a time, but having done that, I find that it's much much easier, faster and
safer to just have a boom truck come out, attach a sling to the top, then
disconnect at the bottom and let the boom truck operator just lay it down.
Works like a champ, is quick and easy. Needless to say, it's going back up
using a boom truck, as I'm not into climbing a tower a dozen times a day any
more. Once is quite enough, thank you. I can get the tower up and beam on it
with a single climb (sling on top of the tower, boom truck lift into place,
climb tower, disconnect sling, boom truck operator connects hook to the
antenna, brings it up to me, and I bolt it in place). Connect the coax already
in place before the tower went up and viola!, tower up with beam in about an
hour. Lots of prep beforehand, but all on the ground where I can take breaks
and enjoy a beer or two during assembly.

Good Luck, Be safe!

Thank you Rick for contributing. I think we have it identified. Lots
of good information was received and it will help prepare to move and
re-erect the tower. Several hams that have look at it commented on its good
condition. It should be an easy move thanks to the guys at my club
http://www.skyviewradio.net/

Any information that was send to me can be found at the page below.

Thanks again,
Paul.
