Pyle Marine Antenna Pyle AM/FM Wire Antenna Black. It works by having two half wave antenna elements one near the stereo headphone port and the other near the radio tuner which usually reside near the earphone port. This allows you to adjust the angle and receive the best VHF/UHF signals from multiple directions. Since the whip is in the shape of a cone it brings the best possible VHF/UHF reception by having two half wave elements. This allows you to adjust the angle and get the best possible reception. It also features a two-way hand connector which allows you to connect it to more than one radio simultaneously. It also has a corrosion-resistant finish which can outlast the elements - remembering to wash your hands after using the product. It also has a weather cover which will resist bottlenecks and withstand a storm. For those short open waves there is a reflector which brings the signal from the tip all the way to the other end of the wire. This helps provide improved VHF / UHF performance. It is recommended that you keep this on hand along with your AM/FM radio and any other noisy uncovered antennas you may have.
