Just an update on the antenna(s) project. On
Sunday October 24, 2010 in the late afternoon, with an
overabundance of enthusiasm, I began to add another 10 feet
to my current mast and also stick a 9.5 foot Diamond 2m
antenna on top.
My old mast is made up of two sections of 10
foot heavy wall, 2 inch conduit, with another 5 to 6 foot
section of 1 inch water pipe on top.
My wife, Misa KJ6BUE and my son, Lou, tried to help me separate
the two sections that are bolted into place on the side of my house - to no
avail. I ended up just removing the entire assembly and moving it to my backyard
and add all the new components. Once in my backyard and the 25+ feet of mast and
antennas laying on the level, I was able to add another 10 foot section of heavy
wall conduit, move my two ATV 1200 MHz antennas down the now taller mast,
install a pulley and rope near the top, and add the Diamond 2m antenna at the
top.
The entire assembly weighed quite a bit, and it was pretty
unwieldy. I tied off a piece of rope about 2/3 the way up the mast and climbed
onto my roof to maintain a position of better leverage. My son and wife were on
the ground and walking the antenna up towards vertical. When we got to about 30
degrees elevation, it was beyond what my helpers could handle. I held on for
dear life, but the mast swung over a part of my roof. and came to rest. It did
no damage to my roof, but the sun had now set, and I could not longer thoroughly
inspect the antennas that were pre-placed on the mast. The ATV antennas appeared
OK, but I was unsure about the 2 meter antenna. My team was starting to lose
confidence in their leader - which actually shows their great wisdom. In any
case, the mast was now in a better position for me to walk over and start
walking it up to vertical. The entire unit was now way too heavy to safely carry over my
roof to my side yard, so once vertical, we lifted and moved the mast about 6 to
12 inches at a time around half my house. It went back into position pretty
well, and we secured it down and put away all our tools for the night.
The next morning, I went out bright and early to see what "she"
looked like. Well, the 2m antenna did sustain some damage. I am sure that it is
functional, but neighbors will now know why it's called "amateur" radio!
I had the mind to pre-attached the 9913 cables with appropriate
N or UHF connectors to all the pre-installed antennas. I made up a new cable for
my off-center fed (OCF) dipole and thoroughly tested it for continuity and
impedance. I attached the OCF dipole balun/center section to my pre-installed
rope/pulley setup and hoisted away. I unfurled the coiled wires from each side
of the dipole in the direction that they would ultimately be attached to
"something", and had to go to work.
The next morning, bright and early, I installed the short
section of the dipole. It ran from the top of the mast down to a tree trunk in
my backyard. I tied a small, loose fitting rope around the trunk of the tree
with a pulley attached. I tied off the end of the dipole to a rope that fed
through the pulley and was tied off to an old red brick. The brick provided a
nice tautness to the wire. Time to go to work. The following morning, I installed a 6 foot x 1 inch water pipe
to the top of my front fence on the opposite side of my house. Again, I tied off
the "long" side of the OCF dipole to a rope and passed the end of the rope
through a pulley, again, attached to the top of the 6 foot tall water pipe. I,
again, used a brick to provide tautness to the wire.
I went out front and looked at my handy work - and, and, and the
bricks and OCF antenna wires seem to be pulling my mast over. Reinforcing the
"amateur" in amateur radio...
I am going to have to guy the mast (which I think I knew
anyway), and my XYL told me she knew! Yesterday, between the Thursday 1930 MDARC
Net and the 2000 MDARC ATV Net, I drilled an additional hole in my pass-through
board into my shack (bedroom) and have fed all the coax into the shack. That
part looks like a fine business and works well.
This weekend will be "guy" time. I am hoping that I can climb to
the tippy-top of my ladder, placed on the top of my roof, and using a long,
extend-able paint pole, push up/over the Diamond 2m antenna to appear more
"normal" and properly polarized.
My XYL has indicated that even though I am half Italian, another
leaning tower of Pisa is not necessary in our side yard! That's what I know now.
I am certain that my Elmers out there reading this are shaking their heads, and
laughing - but I am getting the job done, and hope to get back on the air really
soon!
