Another way to go is to move the GPS receiver so that it is close to
the antenna, then use a long RS232 serial cable. Or if the distance
is more than 100 feet uses a balanced type of serieal. You can use
Cat-5 cable for this and there ar enough pairs in cat-5 so that you
can send DC power on the
Lots of good answers
I do not select a mask
Most of my rcvrs will guess are 10 degrees mask. But that just happens to be
were they come in at.
My antenna is at 45 foot on a 95 foot tower on the south side. There are 70
foot trees around me. I use 1/2 catv hard line very low loss and free. Hit

Hi there. Recently acquired my first GPSDO. It is a datum 9390 (thank you,
Norm!). One aspect of its behavior seems strange to me. Within a matter of
a few minutes, it seems that satellites are appearing and disappearing. Are
the satellites moving that quickly? I might go from 1SV to 3SV or
Shouldn't be doing it that fast
Would indicate a poor signal level might be my guess.
Is your antenna above the tree line?
Wet leaves can be nasty at 1.5 Ghz

Hi Paul. No, the antenna is not above the tree line.
How much of the sky is visible? if you can't see blue the antenna
can't see the satellites. Ok some very minor tree coverage is Ok
maybe but mostly you need a clear view of the sky.
Depending on your QTH, you might only need 10' or so or a chain saw.
