Thanks, the Cross RF looks like a great site. It looks like the connector that needs to plug into the Stratus is a Hirose MS-151-C-LP. That site doesnt carry the Hirose connector. Found a cable in Europe that has the Hirose connector on one end and a SMA connector on the other. So would need to adapt from SMA to BNC. By the way, the Sportys Pilot shop is showing a back-order on the remote antennas for the Stratus until mid-December so that isnt an option for quick delivery either.
