It is a 'special order' item, but as of this morning they have some in stock.

Don't bug the manufacturer (Mobile Mark) about these; they have a minimum order quantity of 250pcs...

Disclaimer:
This is not a product that FLARM has tested, supplies or officially endorses.
It will require the installation of a suitable ground plane and coaxial cables to work properly. Please do not ask us for individual support on this type of installation.

That being said; if installed well, this can be very slick...
