the NCRC-99 no connection radio coupler in production,listed on Etsy

The ERSA portable antennas are light weight and user-friendly, but some questions were raised about what to connect them to for immediate use.
The common TV cable screws right on the back, but after people get a few channels, they want to move on to radio- based use and do some listening work. 
Some radios have a single wire connector on the back, or a 2-screw post set-up for a 300 ohm fm antenna. No provision for a 75 ohm cable or  a "f" connector. 
So after remembering the 2 things almost ALL radios have-the metal telescoping antenna, and the built-in loop-stick coils- I realized what was needed to help people use their new antennas right away. 
The new NCRC-99 coupler unit was designed, built, and tested in the USA, and is now included in most ERSA sales packages so the Antenna is really a "plug-n-play" device. 
The coupler has a light weight cable with a male F connector, so it screws directly on the ERSA unit, then has over 3 feet of length going to the coupler tube.
