Cut a length of speaker wire that will accommodate the height of the antenna that you need, plus 60 inches to make the T part of the dipole antenna. Speaker wire is an insulated twisted copper wire that is made of two joined strands. Make a Dipole AntennaĪny wire can be used to make a dipole antenna, but speaker wire will give the best results. Thirdly, a dipole or other style of the antenna can be attached to the newly exposed antenna wire. This may help to pick up more FM signals, boosting the reception to the internal antenna receiver. Secondly, if you do not want to open the radio, try wrapping an insulated wire around the body of the radio in as many loops as possible. Untangle it and stretch it out inside the room, going up toward the ceiling. There are two options to fix the reception on the radio, such as a clock radio that does not have an external antenna.įirst, unscrew the radio cover and carefully locate the antenna wire that is looped around inside the case. This is the most challenging type of radio to fix, but there are a couple of options. Or, the antenna may be completely internal to the unit.It could also have a single antenna rod attached.It looks similar to a TV cable connector. This is a small metal pin inside of a metal ring. Alternatively, it may have a coaxial type connector.Your radio may have a couple of screws on the back that are labeled “ant 300 ohms.”. There are several types of antennae on radios, and this does have a big impact on how well it picks up FM signals. This does not affect the construction of an antenna but how you will attach it when you are done. Determine the Type of Antenna on the Radio In this case, an antenna must be constructed and placed in an area with maximum exposure to FM signals. This is not always possible, especially for those in basement locations where the FM signal is notoriously bad. Often, the FM signal can be improved by simply placing the radio in a different location that is higher up inside the building. Anything that shares an outlet with an FM radio may also create interference with the signal. Put the radio on its electrical outlet.Rotate the antenna around at each spot to see if there is an increase in signal strength from any point in that location.Closer to a wall or window is better because there are fewer objects to block the FM signals.The radio antenna may pick up signals when it is located near the ceiling or in a window sill. If you know where the FM transmitter or relay is located, point the FM antenna toward it as much as possible. The static will get much stronger when it comes to an interfering appliance or wire.īefore making a new antenna for the radio, move it all around the building and see if there is a better place for the reception. Usually, the source of severe interference can be located by tuning the radio to a low AM station and moving the radio toward suspected sources. Other times, they break up the signals and pass along static. These things interfere because often other wires act as antennas that pick up the FM signals before they can get to your radio. Interior wiring in the walls or attic may interfere with FM signals.Interfering devices such as TV signals, washing machines and other appliances, hairdryers, computers, baby monitors, and anything else that may be plugged in and operating at the same time.This means that it is subject to interruption from many things: The problem with FM radio is that it is broadcast in a straight line. Because the frequency of the audio signals is not subject to fluctuation, it is less susceptible to atmospheric interference than AM radio signals. The frequency modulating (FM) form of radio signals was invented in 1933 by Edwin Armstrong. Understand the Basics of FM Radio Signals Your options below fluctuate between simple and difficult, with great and inconsistent results. Read on to learn how to improve FM radio with a single wire antenna. All of these are do-it-yourself options, but they vary in difficulty level. You can enhance the FM signal strength by repositioning the radio, making a Dipole antenna, or extending the existing antenna. There are several ways to improve the FM signal on a single wire antenna radio.
