Got an amplifier pc board with 75 ohm cable type F fitting to receiver with
I'm going put the 75 ohm type F on one end of my 10' coax interconnect, and a 50 ohm bnc on the other end of my 50 ohm coax.
An alternative is to use 75 ohm coax, and mis-match the other way. This would put a 75 ohm type F fitting on a 75 ohm piece of coax, with a 75 ohm bnc hooking up to a 50 ohm bnc chassis fitting on the receiver.
Which combination will give me the least loss?
What?
with
and
What type of signal? Audio, video, RF? Are you transmitting, or receiving, both?
A 75 ohm source driving a 50 ohm load wil be down
-7.96 db. A 50 ohm source driving a 75 ohm load will be down
-4.44 db Thats in voltage not power. ????
with
and
then again if you are wondering which cable to use, 75 or 50 ohm - Match the cable to the load , not the source. ?????
OK. General senility is nipping at my heels. Geezeritis is chasing me, too.
Just took an in-depth look at the situation and find my receiver has 75ohm BNC input, so no problem. My bad.
Thanks for the ideas and thoughts, though.
One thing about getting old and senile is now I can hide my own Easter eggs.......
