Fun with external loop antennas
#27

Quote:Steve
Nice setup.
Would you have a wiring diagram?
Not sure how to wire that condensor.
Thanks
murf


Murf, the antenna consist of two coils, the tank (main) and the sense. I used 15 turns on the tank coil (I may remove one turn because mine won't tune the high end of the band.) As Brian said the two ends of the tank coil connect to the tuning cap, one to the frame and one to the other terminal ( if you use a two gang condenser, use only one gang.) The sense loop is one turn, spaced about 3/4 inch from the tank coil. The sense loop connects to the radio, one end to the ground and the other to the antenna terminal. Also as Brian said, you might try building a little larger.
