[TowerTalk] weight and sq. ft antenna limits on rohn 25 and 45

[W0MU Mike Fatchett]

I wish I had crankups every now and then.  I am only 44 and each year tower
climbing becomes less interesting.  Guyed or self supporting towers offer
other advantages such as side mounting.

It really depends on your budget and what you expect to put on the towers
and what you hope to do with the towers.

Good luck with your project.

Crank-ups have the advantage (some of them) of being able to tilt

over. Makes antenna maintenance much simpler. You can't do that

with a guyed tower and not many self-supporting towers tilt over.

 

There are some Aluminum ones that tilt over, but they get as

expensive as the crank-up.
