Well, one of the locals and I were discussing a loop antenna. He
insists that the loop is better fed with 65 feet of 75 ohm coax and
then 50 ohm coax to the tuner for the radio. I was saying there would
be less loss by using a 300 ohm twin lead since it was being tuned for
all the HF bands and 6 meters, with open wire or ladder line being
better options. He insists that if the loop is properly made, it is
better to feed it with the 75/50 combo which properly matches the
antenna.

any thoughts?


PS. The loop we were discussing was cut for 80 meters and was to be
used with a tuner to tune all HF bands.

I have no problem loading up (Linear, with Pi network) my 75 m loop on 18
MHz, but performance wise it is a dog. Much inferior to the 18 MHz dipole,
which is not as high as the top of the loop. You might want to run EZNEC on
this. Received signal strtength on other bands is WAY down.. Works fine on
75DX, not so hot for locals.
