[BC] "VSWR" Metering

[cld@admin.umass.edu]

These have been great and informative comments. Thank you gentlemen. May I 
boil it down to "a vswr meter is valuable for viewing the antenna system match 
to the transmitter in general (for those of us without access to a TDR), but a 
good vswr indication should not be taken as gospel truth that there isn't a 
mismatch somewhere"?

Which brings us to the next question- if indeed you see a "good" reflected 
power indication at the tx output, but still suspect something is awry, what, 
in your opinions, are the best places to look (and let's say that you don't 
have the ability to climb a tower and check the vswr at different points nor 
have access to a TDR). Efficiency?
