[TowerTalk] 80 meter dipole

[David Robbins]

it could be lossy coax, or the dipole could be too close to the ground or some other object that is tuned near the 80m band by accident and is absorbing lots of the power.  for instance maybe a rain gutter, power line, house or outbuilding metal roof or flashing, etc.

I recently put up a dipole for 80 and used some RG-6 CATV coax to feed 
it. Good news is that I cut it for 3550 and the SWR is about 1.3:1 
there. Bad news is that it stays pretty much the same all the way up 
the band.

Is the wide bandwildth because the coax is so lossy? It is the double 
shielded stuff with 2-layers of foil and 1-layer of braid. 73
