Feeding a Folded Dipole Antenna.
At any rate, after a bunch of hacking, the numbers started working. Big fun!
Here's the result: A folded dipole antenna input impedance calculator.
If you play with the numbers, and get the input impedance down to 200ohms, you'll need a 4:1 balun to feed it from 50 ohm coax.
The N9XCU 4:1 balun calculatorwill get you close.
Ham's! I need to improve this code. Wanna help? Send suggestions.
Non-engineering types.. Try some numbers. You otta be able to geta divide by zero error somewhere... Or tell me how to make it less ugly...
