The problem is that connectors and coax and dummy loads are the sorts of 
things that can cause things to grind to a halt if they fail, or are not 
of good quality. A dummy load or SWR bridge that's out of spec can cause 
us to make bad decisions about matching in our system, or to 
mis-calibrate it.

El-cheapo coax (or coax that's been wet inside) and junk connectors (and 
connectors that are badly installed) all cause failures that can cost 
big bucks. And all of these problems can be VERY hard to find.

I recently spent more than $1,200 finding and fixing a problem with my 
SteppIR that turned out to be a piece of coax (good stuff) that got 
stepped on near a connector (good connector). It was right outside the 
shack, jumping from 7/8-in hard line to my "ground entry window."

This stuff isn't as sexy as a radio or big antenna, but it's equally 
important. The way to economize on things like this is to find good 
stuff used/surplus, not cheap junk.
