Now small antennas can be made I would suggest to those encombered by
restrictions
to duplicate the following assembly so they may rejoin the hobby.
Obtain a 1/2 plastic pipe.
Purchase two reels of dog fence wire which is pre wound twin wire
Solder the wires of each reel such that it is now a continuos wire.I
used the 20 gauge form from E bay($24)
With the joint at the back of the plastic pipe turn the right hand
side one loop and then the other side one loop but in the opposite
direction.
Procede until you have a wrapped pipe of say a 6 foot length.
Obtain a hula hoop from a store and remove the joining plug.
Push the windings off of the plastic pipe and slide it on the hula
hoop
untill it is full.Replace the plug and connect the transmission lines
to one of each
of the wound wires and solder together
the remaining two wires. Locate resonant points for all bands and
connect to a rotary switch of your choice
for connection for future band use.This antenna will be useable for
all of the top band and upwards.
Each tap supplies enough coverage for any particular band so no
externerl tuning components are required.
As a simple hoola hoop this can be left anywhere in the yard or placed
easily into the attic
where it can only be seen as a childs toy which are always left around
in sight of nosy niebours.
Since it is a closed loop there is little danger of television
problems or high arcing voltage and you may now join the hams on any
band. If you require the loop to be smaller twist it into a figure
eight shape befor replacing the plug.As a listening antenna it can be
placed on top of the tower where it is situated away from ground
noise.

This version is quite light and is an excellent candidate for use via
turning and tilting on a
security observation assemble which allows you to probe the polarity
of incoming signals as well as
cancelling noise that comes from different directions in the loft.
These are now becoming available as cameras get smaller where the
don't need heavy motors e.t.c Keep it as small as possible so it
doesn;t tip the mechanism and break it.
The antenna by the way can be twisted in different directions as long
as one keeps it symetrical (in equilibrium)
One doesn't have to buy a hoola hoop. Common garden water pipe can be
used which makes it more inconspicuious when left outside
with the remaining water pipe.

Art,
"Since it is a closed loop there is little danger of television
problems or high arcing voltage..."

That's news to me Art. I've found that closed loops can produce TVI/
RFI quite well.

And while an antenna of this sort might be capable of letting you
produce a signal on a particular band, it certainly won't be adequate
in most cases. A dummy-load can do the same thing, no switching
required.

None of this means that there aren't a few options available for those
with restrictions! Those options are not going to be 'good' ones,
just adequate,sort of. The root of the problem with living in a
restricted area is that you agreed to those restrictions when you
chose to live there. So, live with them, or move, or change those
restrictions.
