waves are in opposite phase, so giving only the gain of a 1/4 wave. As it is
just a coat hanger it can be bent out of the way & straightened as needed.
CONSTRUCTION
It is made from, "Coat Hanger Wire" or similar fencing wire. soldered into a
standard PL259 plug. You will need a piece or wire at least 23" (58cm) long to
allow for trimming & the plug. (Tuned approx 20" (51cm) free from the plug)

The huge difference in frequency that the aerial has to work over especially on
Band 2, & the resultant poorly tuned aerial. This would never do for Tx, but on
Rx the slightly lower gain of an off tune aerial also attenuates the band noise
just as much as the signal, so there is often little difference in practice if
the Rx system is sensitive enough to be limited by the band noise. N.B. Rx are
75ohm!
A home cut aerial may not look anything like as good as a shiny commercial
chrome one, but ususally works much better!
Why Don't U send an interesting bul?
