[Milsurplus] TBX Field Antenna. Weight?

[John J Mccarty]

 I've been wondering about the weight/strength of the TBX antenna elements
myself. If you've ever put together 21 feet of the MS-54 type of antenna
sections and tried to stand them on end, you realize that you've got a bit of
weight on you hands. Even with the guys and stakes laid out and ready, its more
than on person can handle, even if your very fast. I set up 21' of antenna in my
back yard by myself, but I cheated by leaning it up on the chestnut trees while
 I worked. When the AFD demo came along in an open field, I was glad I had a
bunch of helpers with me. It is amazing how much flex there is in those steel
sections. Anyway, the TBX antenna is 24' and guyed in the middle. Are it's
sections more like the AB series in weight? I can't imagine that it's as heavy
as the MS type and not risk breaking the bottom insulator if the thing starts to
lean.
