Hello Gang,
I have a Northstar GPS 60 that has been working well until the other
week when it simply would not find any satellites. At start up it
runs through the self test everything OK then it starts searching for
satellites says it has 4, 5, 6, etc then has 0. It will come back
and find sats, navigate for a while then drop out again.
I am thinking this is an antenna problem, can teardrop antennas go
bad? can I swap with any GPS ant to test or do they have different
requirements? Is there a coax cable that is best? Or is the problem
elsewhere?
Any thoughts , suggestions would be appreciated.
Thanks
Bob

I would check the coax, more than likely it is RG-58, if it checks bad
replace with RG-142 or RG-400 and yes the antenna can go bad, not
very often but it can.
