Hell,they use them on Dish/DirectTV,etc. What are those,like 5.8+Ghz
systems?
I don't see why they wouldn't work at 1Ghz.


Bzzzzt, Wrong, DBS uses a Block DownConverter LNB out on the Feedhorn,
and the coax running into the receiver is 900 - 1450 Mhz. Thanks
for playing.......



Well,okay then,so it's just the *1.45 Ghz* IF frequency..
So it's good to *atleast* 1.45Ghz.
I'm no math whiz,but 1.45 is bigger than 1.


"Good" is relative......Twisting wires together is "Good" in some
cases, but hardly relevant.... F Type Connectors were designed as
a cheap Consumer Connector for the Cable Industry and for frequencies
below 500 Mhz. Some Folks have used them at higher frequencies, but
they SUCK, when compared to the more expensive "Real World" connectors
like SMA's, MCX, etc. On the DBS Systems, the SNR of the system is
large enough that connector losses, really are insignificant, for the
most part. An RCA Phono Connecter would work just as well, or just as
poorly. Depends on if YOUR Cup is Half Empty, or Half Full.......
