That depends on your antenna design, matching of the transmitter output to the antenna, used frequency and antenna height. I you have a transmitter in the FM radio band with a simple “stick” antenna I estimate you could reach around 10 to 20 km. With a yagi antenna it could be more here the limit is the line of sight.
How far will a 6 watt FM transmitter go?
For a broadcast of 6 watts, the transmission range will be 3 miles. At 15 watts, the range increases to 5 miles, at 40 watts to 10 miles and at 100 watts to 15 miles. The general rule of thumb is it will take four times the power to double the transmission distance.
How Far Will FM transmitter go?
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.
How far will a 1 watt FM transmitter reach?
Because of the way propagation works at those frequencies, a one-watt signal can travel many hundres or even thousands of miles.
How far will 25 watts transmit?
For example, a 25-watt marine radio will roughly have a maximum range of 60 nautical miles (111 km) between antennas mounted on tall ships, but that same radio will only have a range of 5 nautical miles (9 km) between antennas mounted on small boats at sea level.
How do I increase the range of my FM transmitter?
In most cases, you use transistors (and/or tubes) to amplify the RF signal from the transmitter. Sometimes, the least expensive way to increase range is to use a bigger antenna, a higher antenna, a more efficient antenna, or a directional antenna.
How many watts can you transmit without a license?
1. FRS radios are now allowed to transmit up to 2W of power and do not require a license to operate: Formally referred to as FRS/GMRS hybrid radios, these radios will now be reclassified as FRS units using expanded FRS capabilities.
How far can a 50 watt radio transmit?
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. If 1 Million Watts of power is used, it is very likely that signal will only propagate just over 20 miles.
How far can a 50 watt ham radio transmit?
If one station is higher than the other, the answer will be greater than 11.2 miles. Providing that there are no obstacles between the two stations (buildings, hills, mountains, etc.) it should be possible to cover this distance with only 1W.
What is the range of a 1 watt transmitter?
Car, Boat, & Other Radios (Mobile & Fixed-Mount)
|Average Range Guidelines *|
|Wattage||Flat Open Terrain (miles)||Inside Buildings (floors)|
|1 watt (UHF)||2 – 3||6 – 8|
|2 watts (UHF)||3 – 4||15 – 20|
|2 watts (VHF)||3 – 5||9 – 11|
How far will a 25 watt ham radio transmit?
Q: How far will a 25 Watt VHF radio transmit? Under normal circumstances, as far as the horizon. In general terms this is around 30 miles from the point of transmission.
How far will a 4 watt CB transmit?
Transmitter power is limited to 4 watts in the US and the EU. CB radios have a range of about 3 miles (4.8 km) to 20 miles (32 km) depending on terrain, for line of sight communication; however, various radio propagation conditions may intermittently allow communication over much greater distances.
How far will a 100 watt ham transmit?
A little more relevant in this particular space, hams routinely conduct Earth-Moon-Earth (EME, or “moonbounce”) operations, over a total distance of about 470,000 miles, using transmitter power level of 100W or less.
