Instructions
things you'll need:
Radios
Antennae
Radios
1
If you have a radio with a telescoping antenna, fully extend the antenna and rotate it to different angles.
2
If you live in a big city or mountainous area, move the radio to the place in your home that has the fewest large obstacles between you and the radio station's transmitter.
3
Switch from stereo to mono.
4
With a receiver or tuner, connect a wire-loop or T-shaped dipole FM antenna to the back of your unit. Move the antenna until you get the cleanest signal. Use a signal-strength meter or display to gauge signal strength if your unit has one.
5
Alternatively, upgrade to a third-party passive or powered antenna.
6
Install a rotatable roof antenna for the best possible reception. Connect your unit to an existing television roof antenna for the next-best alternative.
Improving FM Reception
If you are reading this, you must probably are in a fringe area, where reception is either poor or variable. The bulk of the following information is centered on low cost ideas for improving your individual reception. There is no substitute for a high quality radio or component receiver though, many boom boxes were designed for large city reception areas and are simply not able to pull in distant signals with ease.
Factors Affecting Reception
FM radio waves can be affected by many factors ranging from terrain to equipment. In general, FM transmissions are lines of sight similar to light waves. Unless an object (building, ridge, mountain, etc) is between you and us, you should have clear reception from the transmitter. Reception becomes a factor of the strength of the signal, as much as your location in relation to the transmitter. KEDU-LP is a low power community station by definition and is licensed for sixteen watts of stereo power from an elevation of 7,560 feet on Pikes Peak Road, opposite the Swiss Chalet Hotel on Mechem.
The following are some suggestions for improving home reception through the addition or adjustment of receiving antennas. These methods may or may not work in all cases, but improving your antenna is the single best solution to reception problems (short of moving or installing a translator). The solutions offered here range from things you can do almost for free, to equipment you can purchase. We are not selling equipment, just passing along tidbits of verified reception lore for your listening pleasure.
Antennas: Some General Concepts
An antenna is a collector of radio signals that improves your reception by providing more signal than would be otherwise supplied to the receiver.
An outdoor antenna is preferable to an indoor antenna.
A high location is better, whether it be the roof, a hill out back, or the top shelf of a bookcase.
Many things in a house can affect reception, so as a first step, try your radio or antenna in different spots in the house.
YOU are an antenna! If you improve reception by standing near or touching the radio or antenna, your system is telling you it needs a better antenna.
A rotorized (pointable) antenna is preferable to a stationary antenna.
Your Radio
Determine whether or not your radio has antenna terminals for attachment of an antenna. These would appear as:
Screws on the back labeled ant. 300 ohms or
A coaxial cable connector labeled coax/ant. 50 ohms
Otherwise, your radio has either an internal antenna that you cant see or a telescoping antenna. Either way, skip ahead to the section No Antenna Terminals.
Connecting an Antenna to Your Radio
There are two different types of antenna cable, flat two-conductor wire known as twin lead that is 300 ohms, or round plastic coated wire that is known as coaxial or coax that is 50-75 ohms. Coax is what cable companies use. It is a much better cable, but it is more expensive. Youll have to decide which to use if you are installing a new antenna or cable. Other than conducting a stronger signal, coax is useful in situations requiring the elimination of interference cause by nearby electric motors, computers, etc. Wed be glad to advise you.
If you have a TV antenna already installed, purchase a FM Splitter at our local Radio Shack Store. Follow the instructions, hooking up the FM output of the splitter to the radio and using the TV output to restore the connection to your TV. Experiment attaching wires to one screw and then the other to see what gets the best reception; the only rule is do whatever works best.
If you receive your TV signal via a cable system and your TV antenna is unused, then just hook it up to your antenna terminals on the radio and you should have dramatically better reception. If your cable system has an FM service, find out if KEDU is carried. If it is, you may want to subscribe to the FM service and eliminate any antennas, or use them in conjunction with the cable service; if it is not carried you may want to lobby your cable company to add KEDU to the FM service. Often cable companies are able to furnish very good signals at great distances from station transmitters.
If you are still experiencing reception problems after connecting an antenna, consider:
installing a motorized rotor to move your antenna from inside,
dedicating an FM antenna to permanently point to Pikes Peak Hill or,
dreaming up some unique arrangement allowing for pointing the antenna.
Using a Di-Pole Antenna
Di-poles are T-shaped wire antennas made for indoor use. You can buy them in many hardware or radio supply stores, and they are very inexpensive.
Attach the bottom leg of the T to the antenna terminals of your radio (experiment while attaching) and then play with the location of the T. The placement of the T is critical to the performance of the di-pole.
If you are really bold, or crave KEDU reception on a budget, you can make a custom di-pole. The advantage is that you can greatly increase a di-poles effectiveness by its size and/or placement outside! Youll need some of the twin lead cable we mentioned earlier.
The custom di-pole you make will be a T just like the ready-made you might buy, except youll be able to tailor it to your needs. However, you need to abide by these, or multiples of these, dimensions; the top bar should be 5'1" or 10'2" or 15'3" or 20'4", etc. and the bottom leg must connect at the middle of that top bar (2'6", etc.) You can drape custom di-pole over the roof of your house, or climb the tree in your front yard and tie it to the appropriate branches (of course, experimenting tirelessly to find the proper orientation of the di-pole for best reception). Twin lead is so cheap that you may find yourself quite proud of the dramatic improvement in reception for a bit of time, but very little money. However, dont kid yourself about the effectiveness of a custom di-pole versus a traditional metal TV/FM antenna.
Cut an appropriate length of twin for the top bar. In the middle of that length cut one of the two conductors and strip back the plastic coating. Now connect another length of the twin lead to the two bare conductors of the top bar. The other end is connected to your radio antenna terminals.
If a custom di-pole sounds like too much trouble, you can make a cut-and-split di-pole. Take some twin lead and split it down the middle. Attach the other end to the radio. Very simple, though not as effective as the custom di-pole.
No Antenna Available? Make a Wire Antenna
Homemade antennas can work very well. Often a piece of wire becomes an antenna without much fuss at all. It can be thick or thin wire, and free or cheap is the best wire around. Wire with a plastic coating is safer (remember to strip any coating away to allow connection of the wire to the antenna terminals), but bare wire is fine.
Use any piece of wire. Attach it to an antenna terminal. Run it over drapery rods and window casings. Throw it out the window and into the nearby tree. Toss it onto the roof. Do the same with two wires. Spend some time experimenting with the placement of these wires; often opposite directions work well. If this is strictly an inside job make sure that you arrange these wires so that youll be proud to point them out to visitors. See my antenna; I get KEDU loud and clear!
No Antenna Terminals
Clock radios normally dont have any antenna terminals or telescoping antennas. Try wrapping lots of wire around the radio; dont connect the wire to anything. The idea is to get a thick loop of wire near the radio.
Almost any large metal structure above ground can act as antenna. Aluminum rain gutters, air conditioning and heat ducts, metal window frames, aluminum siding and metal roofing are great antennas. NEVER USE an electrical outlet as an antenna. Using an alligator clip, attach one end of a single strand piece of wire to one of the above items to the previously mentioned massive loop of wire surrounding your clock radio by simply wrapping the loose end around the massive wire loop of wire around your radio. You should notice a good improvement in reception.
Other portable-type radios have telescoping antennas that may be improved by wrapping a flag of aluminum foil around the top, or attaching a length of wire to the telescoping antenna.
Other Ideas
1. Rabbit ears are cheap and they can be very effective. They do allow you to conveniently move them in many directions for best performance.
2. Select MONO on your receiver. For reasons beyond the scope of this brief information, MONO signals travel farther and have less noise in them.
3. Buy a booster or amplifier for your existing antenna. Sometimes they work wonders, sometimes they just work. Boosters need a certain amount of signal to work with, otherwise they end up amplifying noise rather than audio.
4.
Here is an attic solution. You can install a standard radio-TV antenna (sometimes called a yagi) in your attic. You can position it for the best KEDU signal and gravity will simply hold it in place on top of the ceiling joists.
have a look at the Yagi antenna m sure this will solve your problem as it will be able to receive everything....
