[AFMUG] EPMP1000 GPS Antenna Issues

[Nate Burke]

When we first started using EPMP, (5ghz, with GPS) we had some AP's 
would keep losing satellites.  Then after our first couple installs, 
everything just Worked after that.  Slap the GPS antenna on any random 
surface, and lots-o-satellites with no issues.  Now the New AP's we're 
getting out of Distribution have the GLONASS label on the antennas, and 
we're back to having hit and miss GPS again at new sites.  Are the new 
antennas less sensitive?  At one location, 1 out of the 4 APs was going 
from 12 satellites tracked (20 visible) to 0 Satellites tracked (still 
20 visible) at random times.  We moved the GPS Puck about 4 inches 
vertically, and now it has a steady 17 satellites tracked.

Has something changed with the Antennas?
