[TowerTalk] Boom material.

[jdlambrightatty at gmail.com]

Lee - give me a call. I have an extra 42 ft long 3 in. diameter aluminum boom from an M2 4 element 40M4LLDD. It comes from the factory in 3 sections that are easily hauled on a flat bed trailer. 

. I just finished assembling one and this one is excess to my needs. I have all necessary parts to build the antenna except the elements. 

And no shipping - I'm in Conroe, TX!! 

My cell is 713-851-7576.

I'll use a boom truss but am thinking of aluminum around 3 inches in diameter and maybe 1/4 inch wall thickness.  I realize this won't be cheap.  Maybe this is not even strong enough for a 2 element beam.  I live near Houston, so I am thinking maybe an aluminum provider might be able to sell it to me in one piece.  (Trying to figure out how to connect affordable 6 foot shippable pieces has kept me stumped from starting the project up until now.)

I'm thinking the cost of a boom like this might be in the $300 to $400 range.  (I don't mind splices, but where to get large telescoping tubing?  I wrote DX Engineering and they discouraged me from using their tubing as they said it was not intended for booms even though I wanted to beef it up with sleeves).  Boom diameter is a factor because cast boom to element clamps don't come in every size.  (I have purchased heavy duty aluminum channel stock for boom to element connections to be used with aluminum cast U-clamps.)
