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 at ppinyot dot com KB3LZP |

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.
