GPS and XM Antenna Mounting Position?

[jsharkey]

I was considering mounting the GPS and XM antennas on top of my RV6 Tip-Up glare shield just like the compass.

Anyone else done that? Wiring will be simpe.

I'm assuming that they can "see" through the plexi.

Any other ideas or comments?

Bill Gill (N151WP - see first flight info on the main page) mounted the GPS antenna on a firewall bracket under his RV7 cowl. Don't know if others have tried this, but his GPS seems to get a nice strong signal through the fiberglass...

I don't care for the idea of putting an antenna near the engine due to heat. Dan C has his GPS antenna FWF and had to replace it for an unknown cause. Wouldn't it be better on the glairshield under the windshield? An added benefit here is short and light antenna wire. Is there a down side to this location?

My prime antenna is under the cowl, but I have a backup GPS, 396 GPS, and XM antenna on my -8's glareshield. The downside? You see them reflected in the middle of your windshield much of the time.....

Good info Paul - how good is the signal from the glare shield mount?

Hi,

On my 7A my under cowl antenna location worked fine the first year but this past Arizona summer I has several temporary losses of signal to my Garmin 430 following an intermediate stop and the subsequent heat soaking after parking for 30 minutes or so. After departure and reaching cruise the antenna would resume operation. I'm going to switch to location on the top of the aft fuselage.

My XM and GPS antennea on mounted on the glare shield on either side of the roll support bar on my -9 slider. They are as far fwd as possible without touching the windscreen. Never a problem and almost out of sight.

Do they have a good signal?

My XM and GPS antennas are on the glareshield of my -9A slider. Always work well.
