I'm a VERY happy owner of the 3E model VNWA. I've made measurements on 
my 160M antennas with no difficulty, but I'm out in the boonies, not 
close enough to strong BC signals to have seen any issues.

As to precision of calibration loads -- after I got the VNWA, I did a 
search looking for calibration loads, and quickly learned that if you 
want better than 1% precision, it's easy to spend as much for the load 
as for the VNWA itself!
