Hello 222 fanatics,
I have been fighting high winds after the ARRL EME contest ended in an
effort to repair my 222 MHz antenna system that broke at the end of the
EME contest. WE had two days of very high winds. I had to stop work on
the first day as it was just too windy to be safe while working on the
222 MHz H frame. On day 2, the winds died down a bit after noon time and
I was able to work on the broken yagi all by myself. It broke at the
junction of the rear brace point and a six ft length of the rear boom
got bent about 45 degrees and it buckled the boom. Rather than take the
whole antenna down I figured I might be able to fix it up at 100 Ft. I
got a ratchet strap and hung it above the antenna on the H frame so that
there was no way it would fall if the antenna bolts got too loose. One
of the bottom antennas was broken. I loosened the yagi U-bolts a bit,
then twisted it on the H frame so that the rear of the antenna came
close to the tower. The boom was collapsed and already broken from the
damage and I could now work on it. I removed the 22 ft 1/2" heliax
phasing line from the power divider and coiled it up near the rear boom
section, then removed the rear end from the rest of the antenna,and
disconnected the boom brace bracket located at the rear splice. I had a
rope and pulley installed on the first day and it was easy for me to
lower the boom section and coax. I spent Tuesday night working on the
broken yagi and swapped out the crimped boom portion. Mark, K1RX came
by on Wednesday morning and helped haul the repaired antenna boom up the
tower with me guiding it up. The winds had finally died down with just
some gentle breezes. That was well appreciated. I went up on top of the
tower and managed to get the repaired section put back together, then
strung out the 1/2" heliax back on the frame, and reconnected things.
So the bottom line is that I am back in business after my dumb accident.
In my favor it was awful hard to see clearances with the guy wires and
the antenna when they are 100 ft up in the air. I am working on moving
the guy wires a bit down on the tower so as to avoid any more
entanglements with the guy wires. I had Mark operate the elevation rotor
while I was on the tower and could see any potential problem areas close
up. I need to lower the guy bracket about 2 ft and I will be totally
clear of everything. Onward and Upward.
