Actually, at one time was a antenna_ shortened "Dipole", claimed worst match
was 3:1 literally from
dc to light! turned out, inside the center "insulator", was a 50 ohm
resistor! now, thats lousey effeciency! Jim

Take a dummy load and attach a piece of wire on some kind of a windup
system. To increase the efficiency, let out more wire and vice versa.

Good Idea, and we want to decrease efficiency, so the wind-up system may
just
may be what is needed. What I was looking for is antenna materials that
decrease efficiency.
If we could come up with something as bad as the B&W dipole for a lot
less
money, then we may have something.

Also remember that a terminated rhombic has 50% loss, about the same as the B&W.

==========================

A terminated rhombic does NOT have a loss in the forward direction.
Radiation in the forward direction remains the same as when unterminated.

When terminated it is radiation in the UNWANTED reverse direction which is
absorbed by the termination and suppressed.

But, unlike the B&W, that loss is in only one direction
which turns the rhombic into an effective directional beam.

If GAIN - LOSS 0 you still come out ahead.
