It looks like the "famous" Radio Shack 800 MHz handheld scanner antenna (which is also currently being sold under the Remtronix and Whistler brands) is now also being sold under the Alinco brand name with an Alinco part number. The Alinco-branded antenna is available in both a BNC version and SMA version like the Remtronix-branded antenna (while the Radio Shack and Whistler versions are only available in BNC). At the MTC Radio website it states "Alinco introduces a new line of high-performance Antennas."
