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 David -- KG2LI -- |
