Just some thoughts...

That #26 wire is going to be a problem no matter what type antenna you
end up with. For the longer antennas, HF, etc, it's strength is going
to be sort of limiting. It is sort of difficult to see, but it's far
from being invisible. So, if you are in one of 'those' neighborhoods
that don't like 'visible' antennas there is another choice instead of
an invisible antenna. That's using something that is very visible,
but not normally associated with antennas. The first thing that comes
to mind is a flag pole. Certainly 'do-able', and certainly not going
to be 'simple' if it covers more than one 'chunk' of HF. The 'simple'
way of 'curing' that sort of thingy is to throw money at it, to some
ridiculous point. (Wonder how 'they'ed feel about a 'commemorative'
Atlas missile monument in your yard?)

I think you might do some thinking about what's the longest, sort of
straight, 'run' you can manage using the roof ridge and tree. A few
'bends' in that 'straight' run are allowable, sort of. And then
consider various ways of 'loading' that run. One option might be a
'short' but 'long' inverted 'L', a "lazy-L"? Not exactly the best,
has it's own set of 'problems', but if it works, who cares...much.
Having 'been there, done that' at at one time or another, I really
wish you luck.

===================================
A not 'too' visible antenna ,which might not be recognised as an antenna
is a loop around the house (provided you live in a detached house).
At gutter level at the corners you could fit say 1 foot long 1 inch
plastic pipe pointing sidewards or under a suitable angle.
Each pipe end has a saw cut to accept the antenna wire which can be sealed
with epoxy glue or a piece of tape.
Use a twin wire feeder and a suitable matching unit (tuner ,if you prefer
that word). The loop should work well for all wave lengths equal or
smaller the the loop circumference .

While on a 2 months' visit to the LA area (Torrance) I managed to put up
such a loop ,extended to the end of the garden making it a full wave
length for 75 metres. In spite of being only 10 ft off the ground
(probably making it a NVIS antenna) I comfortably worked the Sacramento
area.
Such a loop is definetely worth a try.

Hi Frank,

No - I have metal siding on the sides of the house and I tried to load up
the siding and the rain gutters, but alas - they are grounded!

I am stuck with something in the air.

A 22' flagpole (with buried radials) can be base-fed
with an SG-230 (for instance) to achieve reasonable
performance on 40m-10m.

Thanks Cecil, but I can't have any flag poles. 73's


Good lord, what kind of neighborhood won't allow a flagpole?
Unpatriotic creeps? Sounds like you need to get PRB-1 in your corner.
Essentially, they cannot stop you from erecting *something*, you have
the right to an antenna. You might not get something really great, but
they will need to accomodate to some extent. A flagpole antenna is one
of those compromises.

Put your satellite TV antenna on a 22 foot pole? :-)

Thanks for your thoughts - I am NOT allowed either of the 2 items that you
suggested (flag pole or missile - although I would like to have a Gatling
Gun mounted and take pot shots at the senior citizens that use my street
as a tune up for drag racing).

----------

Record their license plate numbers and file an official complaint with the
police. There is no excuse for behavior like that, and I'm a senior citizen.

I routinely work anywhere CONUS from Phoenix
on 5w into either a screwdriver vertical,
a hamstick vertical or a pair of hamsticks
horizontal dipole. With those same antennas
and 100w I can work Australia and Latin America.

Mount a hamstick or screwdriver on your car
and run a length of RG58 inside to your transciever.

I think you describe having 90' of roofline.
That's enough for a good sized wire dipole.

Bird feeders, security cameras and windsocks
for some reason seem to work best at 16.6' off the ground.

Here's what one ham did about his neighborhood
antenna restrictions. :-)

Thanks again, but satellite TV antenna must be mounted to the roof, and if I
did want to install a TV antenna, the highest point is only 12 feet above
the roof line. - 73

Thanks Lumpy - I have a screwdriver mounted on my truck, but the HOA says
that I can't run a cable to it.. In the cover of darkness I did run a
cable - and someone complained!

Man, you must live in a tiny place if people
can spot a piece of RG58 lying on the ground
at night.
