Default For those with antenna restrictions

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.
