[OKDXA] Most Rugged Tribander

[K2GKK D C_Mac_ Macdonald]

Somewhere, I have a document that contains that info.

However, I believe that Telerex beams were rated strongest.
I don't know if they are even still made but they were COSTLY.

Mosley beams were rated just a bit less rugged.  Mosley
STARTED the trapped element beams many decades ago
and supposedly Carl Mosley's original TA-33 is still in use
after many decades.  And parts are available for all Mosley
antennas.

I bought a used TA-33 in 1963 in Texas and used it until
1971 (then in Germany) and sold it there before I came back
to USA here in Oklahoma City.  I put another one up here and
had no troubles with it but replaced it with Mosley PRO-67 that
did not survive the May 3, 1999 tornado (along with house,
tower, swimming pool, and 8 vehicles.

I now have a PRO-57-B-30 I am assembling; a six band, seven
element (10/12/15/17/20/30) meter beam which I expect
would require a similar storm to destroy. Mosleys are made
from high strength aluminum tubing.

I had bought a SteppIR, but decided to sell it as I don't have a
tilt-over tower to enable repairs on a complicated mechanism.

I am not a contester, so don't need the last few tenths of a dB
the SteppIR might have provided.  Mosley's traps are wound with
large diameter wire and have comparatively low loss.

 WE USED THE HYGAIN TH11 ON THE NORTH SLOPE IN ALASKA FOR YEARS AND IT HELD UP WELL.  ALSO THE OLD CUSHCRAFT ATB34 HELD UP WELL AND WAS WELL BUILT.
NOT SURE HOW THE NEWER ANTENNAS ARE HOLDING UP, SEEMS MOST ARE NOT AS WELL BUILT AS THEY USE TO BE, THEY SEEM TO BE USING LIGHTER ALLUMINUM THESE DAYS.

Any of the Mosley line of beams. The TA-33 or Classic 33 will serve well.
