Your message shows up just fine in both newsgroups.


Gets posted to both. :) Some clients, like Xnews, will have a setting to show
it only once, the first time it is read regardless of which group that is.
This, and the subject change, are both likely candidates to explain the
behaviour seen. There may be more. :)

There have been designs published in Brit of using the steel of
wind-up tape measures, and this could be a potential starting point
for any discussion, by the use of flat metal tape.


I suspect my notion is not new, but what about a coil of wire, some well-
spaced trees, a long lanyard, a tennis ball, and a spud gun?

Someone will likely have one they prepared earlier, so I won't put the bits
together. :)

A well-tried and tested solution to one problem, but I'd be interested in a
structure that when you go QRT, you could then retract it back.

The problem is that, even if it is retractable, the antenna would still
be in violation of any covenants the home owner's association has (the
FCC has basically preempted most zoning laws for aesthetic reasons here
- although courts have interpreted it differently).

An interesting idea, however. Maybe if you just put it up from 1AM to
3AM you could get away with it :)

Speaking of tape measures, I have an old mil-surplus Hy-Gain Tape
Dipole. Two versions are described at http://www.n2ckh.com/HA4000.htm.


That's very interesting and also proving that there is nothing new under
the Sun!


I'll need to google for the Octopus, though


I agree with Fred that while wanting a beam at a decent height, there may be
some acceptable lower performance alternatives.
At least you could use some of those while still pursuing the optimum.

I've had good luck with an attic loop antenna strung around the rafters and
fed with a tuner.
I haven't had a loop large enough to use on 40 and below, but it worked fine
on 20 and above.

Currently, I use a 14 foot whip mounted on top of a rather large metal patio
cover. It is fed with about 20 feed of RG-8 and a tuner.
Performance is not bad on 20 and above.
I can manually insert a coil to use it on 40 or 80. It is "ok" on 40 and
not so good on 80.

I have a friend who uses a Butternut vertical. It is on a tilt base, and he
keeps it lowered when not in use. His homeowner association has agreed to
that arrangement because it is considered "temporary" instead of permanent.

Good luck.

That is an interesting concept.. however there are several things.. I
would worry about the neighborhood busy body seeing it when it is
deployed and filing a complaint cause, Well, that is what busy bodies
do. And of course you would still get blamed for all the television
issues even if you are not on the air when it happens.. I know of one
ham who was so blamed by a woman who said "See, you are doing it now" he
was standing beside her, not in his radio room (BTW he did figure out
where the TVI was coming from.... HER (Well a heating pad she used)).

How about being patriotic and flying the American Flag,, say from a 43
foot pole in your front yard.. a 40 foot METAL pole, with an insulator
and some other stuff at the base.. In a box (one of those things being a
spot or flood light that projects up to the flag in case you wish to fly
at night).

Seems this might solve the problem as well. (Stealth antenna doubles
as a flag pole)

That said, there are some places where even flying the flag is frowned
upon.. If the neighbors complain about a flag pole.. Call the Marines.
