Make an FM dipole antenna at home using two 5-foot sections of antenna wire. Connect one section to one of the wires in the middle of the other section, strip a small section of insulation from each end, and tie the two wires in the top section together. The process takes just a few minutes.Know More
Cut the horizontal section to 5-feet. Cut the vertical wire to the length necessary to extend from the stereo to the location of the top section of the antenna. Do not cut this section to less than 5 feet for best reception.
Expose the two wires at the end of each section. Strip a small section at the center of the horizontal wire to expose one of the two wires. Cut this exposed wire and attach it the cut ends to the exposed ends of the vertical section. Twist the ends of the horizontal wires together. Attach the bottom of the vertical wire to the antenna screws on the back of the stereo.
Choose the wall where the antenna gives the best signal. Attach both ends of the horizontal wire to the wall, parallel with the floor.
FM radio was invented in 1933 by Edwin Armstrong. The technology uses frequency modulation to control noise static generated by Earth's atmosphere and electrical equipment to improve radio audio signals. Armstrong's invention of the FM radio is recorded as U.S. patent 1,342,885.Full Answer >
The basic difference between AM and FM radio is contained in their names; AM stands for amplitude modulation while FM stands for frequency modulation. The way in which radio waves are manipulated to produce sounds in a radio creates differences which affect the quality of the signal.Full Answer >
Getting better reception for an FM radio involves turning off other electronic devices that interfere with the radio's single, placing the radio in an area where it gets good reception or using the radio's antenna to its full potential. If the radio lacks an antenna, one is easily made using a piece of wire, such as a coat hanger.Full Answer >
A few simple techniques can improve FM radio reception including having a proper and well-placed antenna, reducing any interference and switching to mono when necessary. FM radio waves travel in 6-foot wide paths under and around obstacles.Full Answer >
