[TowerTalk] Multi Band Antenna Query

[ABowenN4OO]

I am considering a backup plus portable antenna. After some research and a 
lot of rationalization, I have decided that an MFJ AV640 will take care of 
my modest requirements. I owned an R7 Cushcraft some years ago, which 
worked reasonably well at about 8 ft off ground, but exhibited SWR changes 
if you elevated it higher or lower. It also did not like high power, over 
about 500 W.

Anyone have comment or counsel on the AV 640? It appears to be free of the 
traps that gave problems when high power was applied to the R7. In any 
event, I probably would not run more than 200 W into the 640; even less 
with portable operation.

It is somewhat cheaper than the competing "no radial" equivalents.

Comments solicited.
