Is a loop antenna a way to get a "long" antenna in limited space? I am
having a hard time finding detailed information on loop antennas. I
have seen some references to using a long wire, but making several
loops which requires much less space.

And the second question is about feed lines. Could I connect 450 ohm
ladder line to the ends of the loop(s) and then run it to a balanced
tuner in my shack? Most references I have seen about loop antennas talk
about capacitors installed at the loop.

Any insight will be appreciated.

Thanks, jimbo
