Barry</pre></pre>Don't know if this has occurred to you but respectfully
you *may* be overthinking this.</pre>If you can't get your '80m ladder
line fed dipole " to be happy with your tuner on 10m, why not just
</pre>add a 10m dipole on the same feed point? ( a la fan
dipole)</pre></pre>This is how I get around "no 15m" on my ZS6BKW (SO2R)
contesting antenna. </pre></pre>The ZS6BKW is fed with ladder line and
then coax and the SWR on 15m is impossibly high, so I merely added a 15m
dipole</pre>at the feedpoint and extended it out to some tiny plastic
spacers 12' away from the feedpoint (instead of 50' away to far away
trees)</pre></pre>This way I have a separate antenna for my SO2R setup
which works on 10-15-20-40 & 80 </pre>(the 'BKW won't do 160m) which I
see is probably the same issue you're having.</pre></pre>It cost me
literally nothing and works very well. See my CQWW CW 15m (so2r)
results on 3830scores.com.</pre>Just trying to optimize 10
meters now, and think I will cut off 1/8 wave and see if it tunes. But
first want to try EZNEC, and see if it gives insight, and maybe get an
antenna analyzer if I can afford.
Thanks for writing.
