This topic has a lot of useful theory’s, what you all need to do is concentrate on buildings in your local area that house a large number of families.
Get to know one of the tenants and explain your proposal of adding an FM radio service to their location. Offer them time on the air and training in return. Either offer them a transmitter or convince them to buy their own.
The choice of FM transmitter used is either up to you or your carrier. How you get your audio feed to them can be done several ways. If you’re already streaming on line, half your job is done. If not, Barix makes devices that sends or picks up the stream over the Internet.
If you use Barix equipment, you can eliminate the need for a local computer, otherwise, you’ll need a computer with Internet access and logged into your IP address or music player.
Once you have this transmitter in operation, post a banner some where, where the residents can see it, or if your local carrier person is well known in the building, have them let their neighbors know by word of mouth to tune to your operating frequency.
Now you have an increased LEGAL audience. Think about it, if the range is a legal 300 feet, and your proposed listeners live in the same building as the transmitter, the walls, floors and ceilings may be thought to reduce the range of your signal, but, there is a difference no one is acknowledging here. Although you are not using actual carrier current with your Decade MS100 FM transmitter by using the included telescopic antenna, your transmitter device and your listener’s receiving device are still common ground to the entire building both are powered up by through the mains supply.
The only listeners that will be depending on your antenna’s signal are those that live outside your apartment building. If they are close enough and the transmitter has exposure to that area, there stands a good chance they will get your signal in FM stereo.
The next possibility, which requires a water tight enclosure, is to place the transmitter up on the roof. This eliminates the obstructions caused by the outer walls of the structure, thereby allowing your signal to reach neighboring homes that are within legal range.
Your listeners that live in the building below that transmitter can still get your signal through the mains supply. Think about it, most people who have FM radios in a home, will use the AC power supply over batteries. So the reception they get will be 100% even if the transmitter is 600 feet in the air on a 600 foot tall sky scraper building. Of course, if your transmitter was 600 feet in the air on a tall building in let’s say NYC, your neighbors outside of the building will get close to nothing for a signal, but those on the first floor of the same building will still get the signal as long as they are connected to the same mains supply.
Being a good neighbor or being well known in your community is a good start. Plus your intentions are to serve your community right? So, assess your local township, focus on buildings that were built to house a lot of families. Try to get a transmitter in that building, then focus on another building. Your best bet is to go after buildings that have the largest number of apartments and get a transmitter in that building!!!
