The easiest method would be to just place the rotator lower in the tower.
If you really want to cut the mast, then a portable bandsaw is the way to go. I
have done this before but I'm not sure I would recommend it.If the mast is cut
in place, you will be effectively felling a tree with almost no safety buffer.
You will be strapped in right next to the mast with nowhere to go should the
mast fall the wrong way. If the mast is removed and strapped next to the tower
and then cut, well, you may as well send the mast to the ground for cutting.

I have a 22 ft (2" OD) heavy duty Cr-Mo mast presently installed up on a 100
ft Rohn 45 tower. It weighs 200+ pounds. I previously had a 4 el 20 meter
yagi stacked 12 ft. above a 40 meter F12 yagi. I just finished removing
both antennas for repairs and have decided not to reinstall the stack due to
the complexity of the installation. I will be re-installing the 40 meter
yagi and some VHF antennas on this tower. Consequently, I would like to
shorten the 22 ft mast by 10 ft.
I am looking for advice on the most efficient way to cut this very thick
high strength mast in place. I would prefer to use battery-operated tools
such as a reciprocating saw(metal blade?) or a grinding tool (cutting
wheel?). I can run 120 VAC (about 200 ft extension cord) up the tower if
needed.
What would be the optimum method for cutting this mast without excessive
tower time? Thanks in advance for any responses.
Vic, N2PP
