Hi

As I work my way through canopy hell, I am wondering about the placement of my GPS antenna. Is there any reason it cannot be mounted on the tail cone, just aft of the canopy. I understand it should be mounted as high as possible, but given the canopy is f/g, I was wondering if the tail cone would be acceptable. Comments front the antenna mavens appreciated.

Inquiring minds need to know.

Les, I'm not maven, but my gyro stabilized gimble mounted GPS antenna
pylon seems to be working just fine Wink .

Seriously, I have one GPS antenna mounted on the tailcone just aft of
the fiberglass cabin cover, and the other on the highpoint of the cabin
cover. I haven't noticed a difference in reception.

Thanks Deems

Hmmm. I may go with the tail cone as it will be an easier install for me.

Cheers

The G1000 installation on our company Cessna Corvalis (formerly Columbia 400) has the #1 GPS antenna mounted externally on a short pylon just aft of the cabin. The #2 antenna is mounted aft of that internally. The GPS signal reception is "certified aircraft" exceptional in all phases of flight.

Guys...
I've mounted my GPS antenna on top of the cabin with the small ovhd console from Dave Saylor hiding the wiring. This is a TNC connector. The cabin top is about an inch and half thick here.

Question is what connector. I've ordered a right angle TNC connector from Stein but it's too short and won't fit through to the antenna. I've searched around on the web looking for a right angle connector with a longer leg but haven't stumbled across one.

Then it just hit me that a maybe straight TNC connector would be perfect since I believe I have enough room for the RG400 to bend.

Or a straight extension would probably work but it'd be another joint in the mix.

SO... those who've mounted the gps antenna on the top of the console, what have you used for connector and where'd you get it if it is a right angle connector.

Thanks,
Doug

Glued the windows in this morning while it was cool. Windscreen maybe in the morning before church.... getting there.

I opened up the hole to make room for the right angle and then goudges
out about 1/4" of the foan and filled it with flox.
