Base of loop will be about 6 feet above ground. RG-8 or 213 will be used for the feed wire. Ugly balun as well.

  • $\begingroup$ Are you feeding it at a corner, or in the center of one leg? Kindly edit your question with this info, so someone can (hopefully) model it for you and determine the feedpoint impedance. $\endgroup$ – Mike Waters May 21 '20 at 17:40
  • $\begingroup$ @MikeWaters this page says that the feed-point impedance of a full-wave loop is about 100 Ω. $\endgroup$ – rclocher3 May 21 '20 at 18:36
  • $\begingroup$ Is your loop parallel with the ground? $\endgroup$ – Mike Waters May 21 '20 at 22:18

Best solution is with an antenna tuner for impedance matching. Cheap-try is quarter lambda 70 Ohm cable (to convert 100 Ohm to nearby 50 Ohm) AND common-mode isolator. I assume your loop is NOT parallel to the ground, since it makes no sense at 14 MHz to have your radiation straight upward. PA0FSB
