Hey TTalkers,
The terror and/or danger in tower climbing is in the eyes of the beholder.
My microwave project in Kuwait would have driven most of
you brave folks nuts. Our prime contractor hired a team of
Yemen-ese [sp]; these guys regularly stood on the top members of
our 100 meter towers without any protection or shoes in temperatures
up to 135 F. The winds on the ground were thankfully never more than
around 40 knots. Not sure what they were up there.
For my purposes, I will hire a reputable tower/antenna man.

Draw a line on the ground. Walk on it. Put a 2X4 on the line. Walk on it.
Put bricks under the 2X4. Walk on it. Put cinder blocks under it. Walk on
it. Support the 2X4 between the first steps of 2 stepladders. Walk on it
.... recover from being terrified by mere visual perceptions. It takes
practice to get used to haat.
What's terrifying is not taking precautions beforehand.

What worked great for DX in 2 previous homes w/ similar size lot restrictions,
was a full wave delta loop, apex up, low corner fed w/ 1/4 wave 75 ohm to 53
ohm to radio. You must have about 50-60 feet of height in the center to string
this up and not choke people in your yard, of course. If the choice is to
string
it up such that you are little bit (key word: "little bit") short of stretching
it out completely; I have used "property-extenders". Put up some TV tubing
(1.5"~) at the property line on each side and tie of the loop. This was an
excellent DX antenna; only improved upon when I put up a 2 ele yagi on the
tower.

I need advice for a 40m wire antenna in my 40ft/12m (E/W) x 144ft/44m
(N/S) city lot, bordered by power and telco lines along the western side.
At the moment, I'm using an 80/40 Off Center Fed dipole (made by
Fritzel), and for contesting it is, well.. mediocre! Adding a rotatable
dipole element to my roof-mounted C3-SS is, for the time being, a
non-starter. I have a 160 inverted-L with 26 radials.
Thoughts, comments, suggestions?
Thanks in advance!
73,
Eric W3DQ
Washington, DC
