How far will an FM transmitter reach?
Being low-powered, most transmitters typically have a short range of 100–300 feet (30–100 metres), depending on the quality of the receiver, obstructions and elevation.
What is the range of a 1 watt FM transmitter?
If the antenna can see 15 miles and say 1 Watt ERP of power used, it’s very likely that about 1 or 2 miles of range will result. This is quite simply because there is not enough power to propagate the signal 20 miles. If 50 Watt ERP is used, it’s very likely that 20 miles of range will be achieved.
How far will 30 watts transmit?
| Watts in ERP | Kilometers Rural area |
|---|---|
| 10 | 8 |
| 30 | 13 |
| 50 | 17 |
| 100 | 24 |
What’s the range of a 50 watt FM transmitter?
This is quite simply because there is not enough power to propagate the signal 20 miles. If 50 Watt ERP is used, it’s very likely that 20 miles of range will be achieved. This is because 50 Watt ERP is ample power to propagate a strong signal 20 miles.
How far does a radio transmitter have to go?
The radio horizon, this is just a little further than the visible horizon, some rule of thumb figures are 20 to 30% further than the visible horizon. What this means is if you look out from where your antennas are mounted with good pair of binoculars, wherever you can see, you will broadcast to and about 20 to 30% further.
Can a FM transmitter interfere with another FM transmitter?
If another operator has a powerful FM transmitter, even 100 miles away, it can interfere and limit the fringes of your service area and signal. c) TRANSMITTER POWER and antenna height, you can’t have one without the other.
How does a 100W radio transmitter work?
If you had 100W then because of the 30 miles line of sight the signal will be strong enough to overcome the background noise in the radio receiver all the way to the horizon. The 100W will reach the horizon without signal degradation. So the transmitter power ideally needs to be proportional to the distance of the horizon.
