Petr - I have 50 feet of these masts and yes, they are strong. However,
they are heavy and require seriously good guying. I also found the
material to be very brittle - far more so than fibreglass. I found
this when trying to drill it. The connecting joints are not that deep
which makes less than 25 ft of these unstable without guying. I use
that amount to support a Pennant. But to put some antenna load on
these in the form of say an Inverted L with a 60 foot high vertical
section would be impractical in my opinion. My sections are about 4
feet long and because you need a lot of them to get any kind of height
the physical instability is increased. I give these a C minus grade
for 160 antenna work.
