Missing GPS Antenna, Damaged GPS Feed/Ground Pin, or Damaged Heat Stake
Figure 4: Back view of RM-11 (3205) C-cover with GPS antenna assembled
The RM-11 GPS antenna is heat-staked to the C-cover. If any of the following events
occurs, replace the entire C-cover assembly:
• GPS antenna is missing
• GPS antenna looks obviously damaged
• Any of the three heat stakes appears damaged; the GPS antenna will be loose
• Any of the three heat stakes are over-heated and the GPS antenna melts into the
C-cover; the antenna will look distorted and bent
• Either the GPS antenna feed or the ground leg is broken or bent so that neither
pin touches the PWB.
