I have no trees, streelamps, telephone poles, or anything higher than a
7 foot trailer. That was why I was considering a vertical. For
practical purposes anything higher than 40 feet is forbidden and 25
foot is as high as I practically dare do.

....[snip]....

Be patriotic: erect a 33-foot metal-pipe flagpole WITH pulley and rope.

Set the bottom of the pole on a strong/thick soda-pop or beer bottle
which is restrained to/in the ground somehow
(I've buried a concrete block -- with its holes
vertical -- until its top is even with the ground
surface, put the bottle in one of the holes, and
filled the extra space with dirt),
mount it firmly to (but insulated from) the top of your trailer, and
feed it with coax
(connect the coax shield to a ground rod driven through
the other hole in the concrete block, the coax center
wire to the base of the tower -- I mean flagpole --
and put a 50-100 Kohn resistor across the connection).

It'll work quite well by itself on 40 and 15 meters, and if you use an
"antenna tuner", you should get acceptable results on 20 and 10 meters
(and higher). With an extra inductor at the base, it should give
passable results on 80 and maybe even some results on 160.

Let your neighbors see you driving in several additional ground rods and
laying lots of radials (although I'm usually lazy and just use the wires
to the ground rods) "to extend lightning protection".

Don't forget to fly a flag occasionally! That's part of the disguise.

Hi,

It seems that my location boasts 60 to 110 mph winds on a regular
basis. I had put up a 1/4 wavelength 20m vertical with 1/8 wavelength
radials elevated at 7 feet, with rope guys... and the wind blew it
apart like so much tin foil!

Does anyone know of a decent commercial design for less than $1000 for
a free standing 30 to 40 foot support that can take this darn wind???

Thanks,

Please tell us where you live to have winds of that magnatude "on a
regular basis". I know of a two places like that, not in CONUS of
course, the site to the south is inhibited year round by US and Russia,
Spain, UK and one or two more that I can't think of right now. Where is
your location?

" 50 miles west of Gallup, NM." . . New Mexico's answer to Mt.
Washington?

I Googled him, seems like the biggest wind in his neighborhood is him.

w3rv,

The wind speed I quoted is intermittent, not continuous.

Seems like the biggest bully in the neighborhood is now you. Why don't
you
put your judgementalism to good use and go beat up on some trolls?

That's what I did.

Then you're blind. The difference between a troll and me is that a
troll has harmful intent to seek to divide the group, like Polymath.
My intent is simply to ask naive questions that people need to ask but
don't because of fear of being punished by people like you.

If I'm a troll, then you're an ogre.
