Terk's FM+ FM Stereo Antenna is a stylish improvement over conventional FM antennas. When placed vertically, FM+ is an omni-directional antenna. Place it on its side and it becomes directional, making stations in certain locations easier to receive. Trek makes connection easy with a slip-on 75-ohm plug. A screw-type adapter and a 75- to 300-ohm transformer are included so you can connect this antenna to virtually any FM radio.
