[50mhz] MFJ 6m yagi feedpoint question

[Danny Pease]

I am sure you can, but looking at the manual, the SO-239 probably should be
insulated from ground. Actually, it may benefit adding a balun to the feed
point, either a choke balun made from a few turns of coax, or a commercial
ferrite 1:1 balun. Whatever you do, the lead length may affect the resonant
frequency slightly. If it does, adjusting the length of the driven element
should get it back to where it was.

Subject: [50mhz] MFJ 6m yagi feedpoint question

Has anyone tried to add a chassis mount SO239 jack to the feedpoint of the
MFJ 3 element yagi for 6m to make hooking up coax easier?  I know the manual
says that you must have very short leads at the feedpoint.  I found that out
once many years ago when I tried to use a dipole center insulator at the
feedpoint.  Can a SO239 use short enough leads to work on this yagi?
