Along the years many frequency counters have been sold out there.
There were regular ones with the so239s in back and some with the so239 and a antenna built in so you can use without jumper cables.
Would anyone have a circuit or directions on a way to make or add an antenna on a frequency counter so the jumper cables/so239 is not needed.
Just place the freq counter close by, keyup radio and freq counter will read the frequency.
Possible add a switch to use with jumpers or the added antenna.
thanks
