As I write this I am looking at a cheap 90 degree adapter that caused me
significant pain about a year ago. In the middle of a QRO contest I noticed
the Alpha's output was becoming erratic. Great, I thought, something is
failing in "old reliable". On a hunch I grabbed the 90 degree adaptor on the
input of the antenna tuner and found it too hot to handle - literally, I
received a blister on my thumb. Of course I swapped it out immediately, or as
quickly as I could as it cooled - the amp went immediately back to its old
smooth, solid output. The Amphenol 90 degree on the output of the tuner was as
cool as a cucumber.
Moral to me - not all connectors, adapters, whatever, are equal.
