i intall my tb6em in one of my tower just to check swr because the first test
was not very confortable, show the swr in the high part or up the ham band of
15 and 20, the 10, is around 28.6
for me is very short the antenna, here in mexico use a lot the 14.100-14200
section like a lot in europe for phone , also the 21.200-21.300 , in that
region of the band the swr is at least 1.5, i check all in the very simple
manual , looks all ok, there are not other holes tha make shorter the antenna
or any other modification from the previos owner, obviusly this is a second
hand antenna , i got 10 years old when was builded.. for that reason , i will
add some u-clams to each section of the 15m band to see if i can low the
resonance to 21.2 , and i will add a pipe at the end of 20m.
i will share my results. if any one have and idea or similar problem , let me
know to see another possible path to lower the resonance of the freq.
tnx to all
