You must 1/3 the length of the tower high to do this that is spec for tilt
over tower spec hygain suggested when they were hygain with the crank up
tower that an a frame be made up for this purpose of 2 by ten wood frame it
will work with right thought going into it, if you can find an old telephone
pole from your local light company that will work just fine for your tilt
post your will still have to back stay it to keep it upright.

Subject: [TowerTalk] Ways To Tilt Over a Light Tower ?
I have a short 40 foot aluminum tower that I use for experimentation - At
the moment
it is serving as a 1/4 wave vertical for 80m. I has 26 ft of aluminum tubing
sticking out
of the top. It is insulated from ground and is sitting hinged on pressure
treated wood legs
buried in a small amount of concrete. I would like to tilt it over easily so
I can play
with top loading for 160meters, etc. I realize that one should analyze
these things from
an engineering point of view, bit I am looking for ideas. I was thinking
about putting
a 12 ft 6X6 with a backstay and pully at the top, that is near the tower and
use a small
winch to crank it up and down - similar to what I have seen used for crankup
towers
while they are nestled. Any ideas? There is no danger of hurting
anything other than
myself, since the tower is in the middle of a field with nothing else
around. The tower
weighes about 80 pounds total.
BTW, the 80m vertical has been a winner this season - several pileups have
been
broken first call.
