Was a direct drop-in replacement for my old Narco mono-pole antenna with quick, easy installation. Bonus is supporting a local USA company (RAMI is here in Michigan). Have yet to fly with it so no pirep on performance. Delivery via USPS was as quick as can be expected, especially during Covid slow downs.
