Garmin quality decreasing?
 
I can't load a flight plan on my Garmin pilot anymore. Need to go another route.

Hello Jack,

Thank you for choosing the GDL 82.

Certified GPS systems have many performance requirements, one of which is low angle satellite reception. The following statement in the antenna installation instructions explains why it is important to not have the GDL 82 GPS antenna too close to another antenna.

"To minimize the effects of shadowing at 5? elevation angles, the GPS antenna should be mounted no closer than 6 inches (edge to edge) from other antennas, including passive antennas such as another GPS antenna or XM antenna."

Let us know if you have additional questions.

Thanks,
Steve

Thanks Steve for your explanation.
Will do as you?ve indicated.

That is where I have the GPS antenna on my -7, works like a charm. Two points 1) the gps cable has to be a certain length (over 6 feet if I remember), if your install is behind the panel that is quite a loop to tie up somewhere, and 2) the antenna is white and cannot be painted so it does reflect in the windshield in hazy background conditions.

What is the consensus on 1200 anonymous mode?

The antennas CAN be painted with some paints, I have my 650 antenna on the glareshield and painted black. It works fine.

The Garmin party line is not supported in practice. I have three GPS antennas on my glareshield that work perfectly. I am moving my XM antenna there too. I maintain that this is why we do not have a certified plane, try it and if it works, it is fine...

No, what your test proved is that it worked on that day. You need to test it under worst case conditions, when minimal satellites are in view, some of them low on the horizon.

It only keeps you anonymous if you squawk 1200 for your entire flight. If, say, you depart from a Class C with a code and then switch to 1200-anonymous when clear, "the system" figures out who you are anyway and shows your entire flight. I "think" (not sure yet), that if you depart sqawking 1200 in the anonymous mode, then get a code when entering a Class C, "the system" doesn't back-stitch the first part of the flight. But that works the same when you're NOT in the anonymous mode. Yesterday I departed Knoxville Downtown squawking 1200 with the anonymous mode off, and flew to Asheville. Flight Aware only showed the last part of my flight when approach gave me a code. All that said, I'm not sure what the allure of remaining anonymous is (Unless someday they institute user fees.) I just don't use it.

I have the GDL-82 and leave my anonymous switch ON all the time. If I'm ever given a squawk code then that overrides the anonymous mode. Why does big brother need to know who I am? The only other time it's off is when I want to request a PAPR report to see if everything is still working properly. I try to request one quarterly.

The GDL-82 is a great unit and it's coupled to my GTX-327.
