Just before New Year's, I managed to obtain a used 72ft. Heights Tower
that had been up for 37 years. Unfortunately, the only recoverable
items were some of the antennas (a Mosley Pro-67A and some unidentified
VHF/UHF antennas with square booms), a Yaesu G-1000 and an Ameritron
RCS-8V. The Pro-67A will need some of the aluminum replaced, but the
main boom and all of the traps are in excellent condition. The G-1000
is in an unknown state, as I do not as of yet have the controller in
hand, nor have I had a chance to hook it up to my current G-1000 SDX
controller to verify its operation. The RCS-8V relay box appears to be
in excellent condition, as far as the relays go. The SO-239s could use
replacement, but a bit of time with a soldering iron and some junk-box
connectors with teflon insulators (not to mention some of the
replacements being female N connectors) and it should work out fine, if
the controller is found. If not, I should be able to homebrew a decent
replacement controller for next to nothing. A 12V power supply and a 5
position switch and I should be good to go.
The problem lies in the tower itself. Unfortunately, it appears that
the tower had been hit by lightning at one point. The former owner, an
SK, had not grounded the tower at the base. As a result, this 37-year
old tower had the joints fused, the stainless hardware was all
corroded(!) and fused and otherwise impossible to separate. As a
result, the person I had hired to take down the tower ended up cutting
the tower into 16ft. sections at every other joint. According to him,
this is how he had been instructed in the past by professional tower
companies to take down towers when the joints could not be separated.
My question is this: Has anyone ever put up a tower that has been taken
down in this manner and if so, what was done to the joints to make sure
they were appropriately strong when putting it back up? If you only
have comments of "Don't do it!" or similar, please save your breath and
the bandwidth. Unless I see some pretty convincing messages on how to
do it safely, I'll be purchasing a new tower later on this year instead
of trying to reuse this beast. (In that case, I'll be taking the
sections to a scrap yard for recycling and pocketing the money for
spending on the new tower.)
