Doesn't Texas Towers and other such vendors sell heavy-duty aluminum mast tubing? Why not try there?
Mark - N9WYS -----Original Message----- From: Repeater-Builder@yahoogroups.com On Behalf Of n3dab For anyone looking for a DB mast to mount their dipoles and harness on, check out all you commercial radio shops for damaged or pulled DB antennas. Don't worry about what band they are on - all you wan't is the mast anyway. DB's are sleeved internally at the center joint with exposed ends of the upper and lower mast sections being cut at a 45 degree angle. The sleeve is secured in the top mast section and slides into the bottom section about a foot. the top and bottom are secured together with 2 SS hose clamps. The base is also sleeved internally for clamp reinforcement. Another source would be a metal fabricator or aluminum supplier and purchase a 20' section of 1 3/4" 0r 2" heavywall aluminum tube and mount your dipoles on it. Wall thickness should be 1/8" thick minimum top to bottom. If you can also pick up a 24" long section of tube to slip up into the bottom to reinforce the clamping area all the better.

I also lack the DB224 Mast that the four dipoles mount on. From my research the original is two pieces about twelve feet long that I believe bolt together, the diameter I have not been able to find. From the ones I have seen the mounting pole is quite robust. Do you have any pole stock that you could recommend that would hold the DB224 on a side mount configuration? As I recall although the mast was very rigid, it was quite lightweight. > > Thanks JIM KA2AJH
