60 Meters on a 102 inch whip
 

I did a little experimenting today with my assortment of Iron Powder Torrid
cores. For those who care;
39 turns on a T-157-2 core got my 102 inch CB whip on the 60 Meter band.
SWR was about 2.5:1. A 2 - 20 pf cap from the antenna side of the inductor
to GND will probably get it to 1:1 though I haven't bothered to try this
yet.

Have fun

What do you imagine the radiation resistance ( and therfore efficiency) to be?
