Hi Steve,

wish to add just one comment sharing with you my experience.
For routine tests or measures on antennas since almost a dozen of 
years use an home made VNA (I realized the N2PK VNA and still works 
fine!) this make available visual and numerical datas which very 
important to understand what I'm doing. As everybody, of course, I like 
to have an instrument in line while transmitting just to see is 
everything is "normal" and under control. For this purpose I made a 
small console which includes the low pass filter, an RF ammeter and an 
SWR bridge is very easy to design and make yourself such instrument I 
made mine covering from 137kHz to 160m and I guess it is reliable at 
least as all "in line" meters.

Many thanks to all of those taking the time to reply to my inquiry. It 
seems 
that results vary depending upon what meter is being used but it sounds 
as 
though only a few are having reliable / accurate results. I normally 
use the 
scope match and call it the 'most valuable piece of gear in my shack' 
but 
was curious about suggesting the use of an HF SWR bridge for those that 
do 
not yet have such a thing, and if it would be a reliable method of 
matching 
an antenna. In some cases 'yes', but it seems, in most cases, may be 
unreliable and only lead to confusion.
