Default what a 1:1 choke balum used for

To sort of sum things up, then what should I use for a choke balun on
75 meters, 77, 73 or 43 mix? More the better? I read the W2DU article
and he used 73, but I thought 77 may be better?


Hi OM,

More is better? What do you seek to achieve that is not already
answered by Walt's article? Didn't he specify which type?

#64 material is going to offer about 3 Ohms per bead;
#43 material is going to offer about 8 Ohms per bead;
#73 & 77 material is going to offer about 18 Ohms per bead;
#75 material is going to show offer 28 Ohms per bead.

If you are running power into a matched load, you may want more of the
lower resistance beads. If you are running barefoot, fewer more
resistive beads will work.

Or you could do it the old-fashion way by looping your coax at the
drive point.
