I have started to experiment with EZNEC and am modeling a couple of loop
antennas including some delta loops. I see references to hams using 4:1
baluns with these antennas, but the models I see show a feed point
impedance of roughly 100 ohms. I'm not sure how a 4:1 balun would help -
what am I missing?

Thanks and 73,

the simpler match is 1/4 wave of 75 ohm cable.
