How far will a 10 watt FM transmitter go?
If the antenna can see 20 kilometers away, but an ERP of 10 Watt is used, it is probable that no more than 8 kilometers will be covered, because there is not enough power to propagate the signal as far as 20 kilometers.
How do I calculate FM transmitter power?
how do you calculate the Wattage of FM Transmission of a typical FM Transmitter? Measuring the voltage at the antenna is the only direct way. If you antenna is a quarter wave monopole it will have a radiation resistance of about 37 ohms and so if you have 2 V RMS (VHF/FM) then the output power will be 4/37 = 108 mW.
How far will 1W transmit?

---|---|---|
Wattage | Flat Open Terrain (miles) | Urban Areas (miles) |
1 watt (UHF) | 2 – 3 | ½ – 1¼ |
2 watts (UHF) | 3 – 4 | 1 – 1½ |
2 watts (VHF) | 3 – 5 | ¾ – 1 |
What is the maximum range of FM?
The frequency band for FM radio is about 88 to 108 MHz. The information signal is music and voice which falls in the audio spectrum. The full audio spectrum ranges form 20 to 20,000 Hz, but FM radio limits the upper modulating frequency to 15 kHz (cf.
How far can a 3 watt radio transmit?

---|---|---|
Wattage | Flat Open Terrain (miles) | Suburban Locations (miles) |
2 watts (UHF) | 3 – 4 | 1½ – 2½ |
2 watts (VHF) | 3 – 5 | 1½ – 3 |
4 watts (HF) | 5 – 6 | 2½ – 4½ |
How far will a 1 watt transmitter go?
With a line of sight of about 15 miles 1W ERP of power will probably send the signal only 1 mile or maybe 2 miles, this will be the limit because the signal is just not strong enough at more than 2 miles to overcome the background noise that’s present in all radio receivers even though the line of sight is 15 miles.
How far will a 6 watt radio transmit?
Some handheld radios have 6 watts which can reach up to 20 miles in the right conditions.
