I'm working on a GE 107 radio that has a loop antenna glued onto a wooden panel backboard. The antenna was rusted and popping off and the backboard was taped together and falling apart.
I made a replacement backboard and attempted to remove the loop antenna for a "transplant operation"...needless to say it's not looking good for the patient.
So. I'm thinking about attaching some short sections of wooden dowels to the board and wrapping my own antenna. But I've never made one before and am unsure of a few things...like what type of wire, how many wraps, etc.
The schematic specifies 2.5 Ohms for the antenna on this model. Do I just keep wrapping till I hit the Ohm target? i'm sure there is probably an equation where wire diameter, length and resistance can tell me how long of what size wire I need, but that math is beyond my current comprehension.
