[TowerTalk] Broadband Match of 80/75M Dipole

Besides the high SWR and associated feedline loss that Jim mentioned,  
the antenna pattern would have multiple deep nulls.

In my limited experience, no. My high (120-140 ft), coax-fed resonant
80M dipoles exhibit VERY high SWR on 30M.  A good tuner might put some
power on the transmission line, but the loss would be very high. The
fact that they don't hear well on 30m is a clue.
