A simple dipole is 468/freq = length in ft...using 100MHz as a nice round
freq, that makes the dipole 4.68feet...
For ease of construction, call it 4ft 9in....that makes each leg 2ft 4.5in
long...connect 75ohm coax to it and to the rcvr (any length will work) and
raise the dipole as high as you can get it....Most FMs use Circular
Polarizaton (those that don't run Horizontal...VERY few use Vertical and if
they do, they are in the 88-92MHz range to avoid trouble with TV6) so even
if you don't get it exactly horizontal, its not a problem (think rabbit ear
TV antenna here ;)
No caps or resistors needed...
Note a dipole has NULLS off the ends of the elements.....for best reception
you may need to rotate the dipole around.
