[50mhz] Balun on 6m yagi

[Chris Boone]

Wouldn't hurt...a 1:1 current balun or coax choke may improve the
pattern.....(but a Crunchcraft antenna needs improvement anyway...much like
anything by MFJ today) THAT or some snap on ferrite coils like RS sells (or
used to)...a few of them will kill RF down the shield as well...and easier
to work with...just tape or tywrap in place

Subject: [50mhz] Balun on 6m yagi


I hope I can get some clarification or advise from list members on this.  I
have a Cushcraft A50-3S 3 element 6m yagi and am getting ready to do a
little antenna work this week. Currently I have the coax running directly to
the SO239 on the yagi, as the manual states.  Would adding a coax balun (a
few turns of coax by the feedpoint) improve performance in any way?  I have
seen this recommended for other antennas but the Cushcraft manual never says
anything about it.  It does seem that it would keep any stray RF off of the
coax shield, correct?
