wire parallel to the chimne

with

little risk of detection. Some short

standoffs and

ou have a support for

a vertical dipole type antenna.

C. Along the edge of the roof, held

off by some inexpensive TV twin-

lead standoffs, you can hide 25 to 40

feet of antenna on virtually any

clear of a buildin

pe of installation is

a favorite. If the feed-point is at

ground level ad

acent to an iron or

copper water line enterin

the house

counterpoise.
