Topband: 80/160 trap vertical

 make a 160 inverted L and operate it also as a 1/2 wave vertical??

Hi Ed,

That thought has crossed my mind and sort of tried it once. I 
replaced the coax with open wire line and used a balanced tuner, 
Rich Measures design (QST Feb 1990). It worked FB on 30, 40, 
and 80 but I couldn't even buy a Q on 160. Reattached the coax and 
it performed as it should on 160. Maybe someone on the list could 
explain that one for me. The openwire line was about 80 feet long. 

Thanks for reminding and in the future I would like to try a remote 
system of matching the feed point to other bands. This will be a 
good project when school is out.
