KOPN Antenna
antenna

You can make an antenna to better receive KOPN. FM antennas work best when they are sized for the wave length you are trying to receive. KOPN's wave length at 89.5 MHz is 10.99 ft. A folded dipole antenna can be made from a 5 ft. 6 in. length of 300 ohm twin lead antenna cable. Strip both ends of the cable. Twist the two wires together at each end and solder the connection. Cut one of the wires in the exact middle of the cable and strip back both ends. Connect these two ends by twisting and soldering to whatever additional length of twin lead cable you need to reach the 300 ohm antenna connection into  your FM receiver.
