You absolutely can walk up a 40' aluminum tower because I have done it, but
probably not with anything on top of it. :-) For Field Day we do the falling
derrick routine, except for us it's a falling ladder, with a 50' aluminum tower
with either a Spiderbeam (ultra lightweight), or an A4.

Since the video we've added another section for a full 50'. Rope is used for a
rotator, tied off to a ground stake, and a homebrew tilt plate gadget gets the
antenna horizontal by pulling on a rope. Four way guys are required for this
arrangement.
Ladder climbing antics aren't for everyone. Two guys pulling on ropes tied to
the top rung can accomplish the same objective.

I keep seeing ads for self-supporting aluminum towers that are so light that
one person can "walk up" a 40-footer with a hinged base. Of course, walking one
DOWN might be more interesting, unless one has ropes, blocks, and a team. Can
walking one up really be done, even with light, VHF-UHF verticals and/or TV
antennas? It just seems a tower light enough to walk up can't be strong enough
to STAY up.
I can't afford a motorized tilt-over or telescoping crank-up, unless it's used,
and even then, it's unlikely, on my retirement income. All I want to tackle is
30 to 40 feet. Should I forget about a tower altogether, or buy a section of
Rohn 25 a month, or... what?
