Question about GPS antennas and radar

[IRGuy]

I was recently told by someone who is usually reliable that you should not mount your GPS antenna where it will get a direct hit from your radar antenna as it rotates.. that radar exposure will damage the GPS antenna.

Can anyone here verify this?

According to NMEA.org...

• GPS, Satellite & Cell Antennas must be outside Radar Beam
• GPS Antennas below SATCOM Antenna Beam
• Cell Transmissions Can Interfere with GPS Reception
• Multiple Radar Antennas at Different Heights (18”)
• Sat TV Spacing Dependent on Radar Output Power
