to secure the joints with hose
clamps or plumbers tape to
assure low resistance connec-
tions.
C. Masonry chimneys are
visually "busy". You can run
a #10 copper wire parallel to
the chimney with little risk of
detection. Some short stand
offs and you have a support
for a vertical dipole type
antenna.
D. The Inverted "L" antenna may work slightly better if it is installed
clear of a building, but for covert operations, this type of installation is a
favorite. Especially if the feedpoint is at ground level adjacent to an iron or
copper water line entering the house which will provide an excellent
counterpoise.
E. Along the edge of the roof, held off by some inexpensive TV twinlead
stand offs, you can hide 25 to 40 feet of antenna on virtually any house.
F. Under the roof overhang, all kinds of wire antennas may be installed.
G. Loop antennas installed on the inside or outside wall work well at
higher frequencies and provide some directional characteristics.
These antennas are also less prone to man made noise.
H. All types of antennas may be hidden inside the roof of a building
which uses non-metallic roofing materials.

There are a couple of antennas which don't fit into any category in particu-
lar, but which should be mentioned because when used with a Smartuner,
they will deliver spectacular results.
55..66 KKIITTEE AANNTTEENNNNAA::
This is our recommended antenna to be carried aboard all types of vessels.
This is because when a wind strong enough to damage a boat occurs, it is
easy to fly a kite and this may lift fifty to one hundred feet of antenna wire.
For good emergency communications, you will only need 30-70 feet of
