hi

I was wanting to dispel some myths about connector losses

lets assume my worst case freq 450mhz LOW /week singal work

lets assume my worst coax is ether lmr400 or 600 (not imp )

so naturally i'd use typically N connectors

how much do i lose if I screw in a right angle adapter?


My comment would be on the right angle N connectors. They vary dramatically.
My area of interest is 1296MHz EME where any loss before the Feedhorn LNA
shows up easily. I have an HP network analyzer and qualified a number of
right angle N's. In general the adapter with a square block at the elbow
were fine- under -0.03 dB. The gradual bend (called a sweep in plumbing
terms I believe) had unacceptable return loss and much higher loss (sorry,
no figures there).
