All you need is a length of plastic-insulated wire strung up in the
attic, or unobtrusively tossed out of a window, and a large aligator
clip attached to the domestic plunbing system. Plus a simple tuner.
Believe me - it really does work very well! Ask any real amateur.
And don't get yourself all mixed up about so-called SWR, reflected
power and take-off angles.
