[TowerTalk] Source for aluminum tubing?

[Wayne Kline]

Brad,



I  echo John’s  statements.. I have always used  replacement 7/16 odd dia tubeing from Hy-Gain  now MFJ

And ALWAYS use polly proplean as anti dampening  for survibility.

Brad that is a tough size to find. I used to buy Ø7/16 with a 0.049 wall from a ham in Ohio that sold 6061 tubing however he retired. I had a bunch of extra heavy duty tips in Aruba that I gave away when I sold my station. I have found Ø7/16 online though commercial sources but it was pricy for low quantities. You need to purchase drawn tubing for a proper fit. Perhaps DX Engineering should pick up this size. Hy-gain tips break easily, at least they have for me and I only used them for temporary contest antennas. Probably the least expensive and easiest place to buy a tip is though Hy-Gain.

​Hello all,

I am rebuilding an old HyGain 153BA 3-element 15 meter monoband yagi and I
was wondering if there is a good source for the 7/16" diameter by approximately
.039" wall thickness aluminum tubing that is used for the ends of the element
half-sections?

Years ago, Texas Towers used to stock a wide variety of aluminum tubing but
on their web site I see only two sizes listed.

Thanks for any help with this!
