This is good advice. Guys who do lots of portable setup say to always 
check the coax first, which mostly means check for a connector that's 
bad or badly installed.

In general, if it doesn't say Amphenol or isn't stamped with a MIL spec 
number, it's very likely to be poor quality. This includes barrels, 
adapters, etc.  Also make sure that every connector is" wrench tight."

The advice to run it straight to a dummy load is right on -- if you have 
one big enough. :)
