Versatile but not for heavy antennas
|
Time owned: more than 12 months
|
I bought one of these just before I got licensed to get something up quickly. I assembled it and put it up straight without anything attached to it and yes, it collapsed into itself with only light swings caused by a light breeze. No real damage but I could see the marks of the crash.
To serve as permanent support, something needed to be done.
It ended up as a support for a 20m inv V antenna (2x5m) fed with a balun. I taped all section joints together with duct tape, and put the small balun on the third section counting from the top. The top sections are too small to attach something on to that pulls it sideways, except for a wire that runs down parallel to the section. I made 2 brackets and used this to attach guy wires (nylon cord) in 4 directions (90° spreading), at 4m and 8m high.
Like this, it has been in use since November 2000 and has withstand summer heath, winter cold and heavy (really heavy) winds. Without the tape and guying it up, this wouldn't have lasted this long.
I bought a second one for temporary use, for additional dipoles, verticals or loops. I always tape the joints here too, because it just won't stay up. If you know this (and now you do) and take it into account, and your goal is a versatile solution for light wire antennas, then you just can't go wrong because the quality is good.
Bottom line: if this is what you need, and if these setbacks aren't a problem, then just go for it.
