after several test and diferentes changes using the original telrex balun, i
remove it, and my swr is very good, the best i can get in all the bands using
the original balun was 1.5 flat across 20m all the band, in the 15, was good,
1.2 one edge to 1.6 the higher edge,
10m was very narrow and only 1.1 in the 26.6 and narrow. a few 400 khz.
i add 2.5 inche at the 20m driver at each tip, and my swr is 1.2 in the lowest
and 14.0 1.4 14.400 1.5 very good to me.
15m 1.3 21.000 and 1.5 at 21.450.
28 .300 1.5 29.2 1.5 looks good to me ,
all this last result using only coax cable no ferrite beads, or any other balun
i will test using ferrites and later comercial baluns, and i will leave the
one that lower swr across the bands..
really the telrex balun get old and become useless.
and no low swr in the channel 19 cb , like some post say..
