Stealth antenna idea
 

I haven't been monitoring the group for a while. Wondering if anyone
has considered two screwdriver type antennas mounted horizontal in a
dipole fashion in the attic and appropriate control to acheive a
tuneable attic dipole. stealth in CCR is the motivation.

Sounds like it would work, to me, but if it were me I would use wire
instead. You can probably place wire more effectively in your attic and
just use an SGC antenna coupler to tune it at the feedpoint. Would
probably not only work better, but would be cheaper, too.

Most hams use one screwdriver antenna with various
lengths of counterpoises.

I suppose someone has written on the topic before. But is that like a
crime in this group?

I suppose a person might with a lot of effort to synchronise the
screwdrivers, and a whole heck of lot of money for the screwdrivers
themselves, manage to put a really mediocre antenna in their attic!

There are a lot more cost effective solutions out there.

Yeah, Mike. That was my take, and the reason I suggested wire
antenna in attic with an antenna coupler/tuner up there.

Yup, this is an old dead horse we are beating, several times now...
Peruse the archives over using a pair of mobile whips as a dipole...

Don Johnson in one of his 1990 books featured a photo of a dipole with two
screwdrivers in the 90's. Since hams can build a screwdriver for about $50
each maximum if good scroungers, it's doubtful an SGC tuner is a cheaper or
easier solution than said screwdriver dipole.

Such an antenna won't be a great antenna, but then again an indoor stealth
antenna is never going to be competitive with full size outdoor antennas
well removed from buildings and the like.

I'ld personally rather be on the air rather than arguing the merits of a
screwdriver antenna versus an autotuner with wires and counterpoise.

Can it be done? Sure.
Has it been done? I'm sure it probably has, I've just don't remember
hearing about it.
Would it work? Certainly much better than no antenna at all!
Would it be difficult to build? Just depends on the builder's
imagination and how 'handy' he/she is.
Would there be a commercial market? Probably a small one, with all
the characteristics of a small market.
Are there other ways of going about it? Sure, refer back to that
imagination and 'handy' thingy.

OK. Problem with avoiding this is that I do not go back and read
archives everytime I see a post on which I may comment...... I did not
remember seeing this one before....

Hi John, I am also in a deed restricted community and share your pain.
Here is what I did for HF - I installed an Inverted L antenna that goes
up and over one tree (approx 30' high) and across to a second tree
(approx 75'). It is fed at the base with a SG-230 Smartuner. The
'second' half of the antenna is 59 ground mounted radials that go out in
straight lines and vary in length between 35' and 75' based on how
long I could run them to the property line or other obstruction. The
ground radials were stapled to the turf every couple of feet and are now
invisible. The only visible part of the antenna is the horizontal wire
running between the two trees, but because of the way my lot, house and
other trees are arranged in the backyard, the wire is only visible from
my back porch!

The antenna works quite well on 160 - 10 meters, and is a big
improvement over previous attempts to make something work in the attic
because it is outside, well clear of the house everything inside that
generates RFI. I got advice on the radial system from Tom, W8JI and
Rudy, N6LF and their great web sites listed below.

For 6 and 2 meters sideband/cw I have Par Omniangle 'loop' antennas
installed on a pole that I placed in one of the tress in the backyard.
The 6 meter antenna is at 20' and the 2 meter one at 15'. All three
feedlines are buried where they run from the base of the tress to the
house entry point. A little more info plus a couple of pictures are on
my web site.
