If a multiband antenna is your goal go as big as you can fit in your space without regard for its shape. Get a tuner. Run a twinlead from the antenna feedpoint as close as you can to the tuner, then transition with a 1:1 balun to a coax to the tuner. If you have a balanced tuner forget the coax.

If you want an 11 meter loop use tuned dimensions, a 2:1 balun at the feedpoint, and coax to your radio. If you use the rectangle shape I suggested, only a 1:1 balun is recommended.

The loop in my attic is a 4 square fed at the corner with a tuned length of 300 Ohm feedline and a 4:1 balun to coax feeder to radio. I don't care about a 1.4:1 SWR.
The rectangle design I have tried only in the open. It worked, then came down as I moved on to other experiments.
A versatile and inexpensive analyzer is the mini 60. Some like the miniVNA. I don't because I dislike the menu layout. I like simple.
