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

Folded Dipole Calculator
The impedance of this antenna is around 300 ohm, so you may want to use a transformer or a 1/4 long piece of 120 ohm coaxial cable to match this impedance to 50 ohm

Impedance Transformation with Quarter-Wave Lines
The input impedance of a line an odd multiple of 1/4 long is
