Correction:
Make that 'don't mix 80 meters and 30 meters on the same coax'

I failed to mention another point with regard to fan dipoles. Do not
mix 3rd harmonic radiators on the same coax. In other words, stay away
from combinations of 40 meters and 15 meters, and also 40 meters and 30
meters. They may work, but tuning problems are 'iffy'.

One other comment regarding fan dipoles.
They really work well, but if one attempts to put more than 3 bands
on a fan dipole, the interaction can become frustrating to tune them
all, been there, done that, and have all the scars.
Strongly agree. Also, fans work best on harmonically related bands.
80/40 works very well, so does 20/15/10. 40/30/20 not so good.
I use separations of about 9 inches for 20/15/10, and about 15 inches
for 80/40.
