Is there away to hook up my Terk Advantage Antenna to my Grundig Satellit 750?. The Terk antenna came with a connecting cord with a jack on one end to fit in the antenna. The other end is just two bared wires. I tried soldering a jack to it so it would go into the rotating antenna on top of the radio. It works well close to the radio but just wondered if it would work better connected. Thanks .
