Guys, I'm having trouble locating the old school wire cell phone antennas with the magnetic base mount. RadioShack now only sells a plastic "universal cell phone antenna" that is not the same thing. It has a screw on connector instead of the bayonet connector, so I don't know how well it works. But I would really like to just find one of the old wire antennas. Can someone point me to a place to buy/order these? Thanks.
