I have a 75 meter delta loop. Full wave. Want to feed with coax. Do I use a balun (if so what value) or a tuning stub of 75 ohm with the main line of 50 ohm. If so what would be the tuning stubs length.

Feedpoint impedance of a delta loop can vary widely, depending on exactly where the feedpoint is located along the loop, and the height of loop above ground. Please provide more details of the loop construction.
