Unless you go the route of feeding with twin lead and a tuner (and, yes I
know several local hams that do so successfully), then you need to back up
and look at the impedance of your driven loop, and the impedance of your
feedline - a balun, if used, will match those two impedances. For example,
a 300-ohm element with 50-ohm coax would require a 6:1 balun.

Hope that helps. Good luck!

Hi, group. I'm considering an attempt at building a quad antenna for 11
meters.
The plans I have, leave some of the details to the builder.
It's my understanding that the driven element needs to be fed VIA a balun.
I emailed a person with baluns "for sale" listed on ebay. He replied that
he
thought I needed a 4:1 balun for a quad.
It's was my understanding that the balun should be a 1:1 ??

Anyone in the group care to advise me on this question ??

Any help and /or advise on the building of the 4 element 11 meter Quad
would
be appreciated :-) !!

Thanks
