Easy $50 Savings over Garmin GA24TNC SXM Antenna
Here's Garmin reaching into your wallet yet again for another
accessory to get full functionality from their devices that you've
already paid a premium for. Your GDL52R requires a TNC connection for
the SXM antenna. Go try to find a TNC SXM antenna except Garmin's GA24TNC for about $77 and let me know how that works out for you.
For under about $25 it is possible to bypass the $77 profit fattening
antenna accessory from Garmin and create a functionally equivalent
antenna to receive your SXM subscription.
The two items pictured below are all that's required - a conventional SXM antenna at approximately $15 from eBay and a short length of SMB Male to TNC Male adapter cable at about $8, also from eBay.
Enjoy your low cost alternative to the GA24TNC antenna and enjoy the
12 or so gallons of Avgas or a couple of filet mignons or that favorite
adult beverage that you can spring for without feeling guilty!
PS: If you are mounting the SXM antenna near any compass or
magnetometer, the usually fitted magnets in the bottom of the SXM
antenna can easily be removed from behind the label on the bottom of the
antenna. A hook & loop (aka Velcro) strip can then be applied to
the back of the antenna for removable mounting.
