All:
We have had a panel mount Garmin 396 in the plane for some time. The antenna has always been mounted on the glareshield with the mini-suction cup mounts. We moved the panel around a bit and now actually have 2 panel mounted 396's. The antennas are now both mounted with velcro to the dash. We are now experiencing lost satellite reception periodically during the flight on both 396's. The 530 is not losing reception. We called the avionics shop and the response was that the antennas were getting hot on the dash. If that is true why were they not getting hot with the suction cup mount. The antenna is essentially in the same place just now it actually touches the dash instead of mounting to the bottom of the windshield. Any help is appreciated.
