How many watts do radios use?
Most handheld two-way radios on the market today use between 0.5-5 watts of power to broadcast a signal. Some business radios are designed to run on slightly more power – between 1-5 watts depending on the model. In general, a higher wattage allows for greater range.
How far can a 5 watt radio transmit?
The 5 watt radio can reach up to 12 miles or more. Some handheld radios have 6 watts which can reach up to 20 miles in the right conditions.
How far can a 1 watt radio transmit?
Car, Boat, & Other Radios (Mobile & Fixed-Mount)
| Average Range Guidelines * | ||
|---|---|---|
| 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 |
How far will a 1000 watt FM transmitter reach?
If an ERP of 1000 Watt is used, it is very probable that the signal will reach 20 kilometers, and it will also penetrate eventual obstacles.
How far can a 2 meter radio transmit?
Typical reliable repeater range is about 25 miles (40 km). Some repeaters in unusually high locations, such as skyscrapers or mountain tops, can be usable as far out as 75 miles (121 km).
How far can marine radios transmit?
Your VHF radio is intended mainly for short range communications, generally 5-10 miles, and at least 20 miles to a USCG station. To communicate at longer ranges, you will normally need a satellite telephone or an MF/HF marine radiotelephone.
What is 433 MHz band used for?
433MHz is a commonly used frequency band for all types of equipment that require little power, such as garage door openers, headphones, baby phones and remote controls. Also many inexpensive transmitters and receivers for switching devices and light dimmers operate on the 433MHz band.
How far can a 10w radio transmit?
Thus the typical ranges with around 400 MHz frequency range with 1 W transmitter power are up to ~30 kilometers and up to ~80 kilometers with 10 W transmitter power. See sample picture of a RF link functional factors at the end of this document. The links can be extended by using repeater radio stations.
How far can a 15 watt radio transmit?
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.
Are CB linear amplifiers illegal?
Although the commission has eliminated many citizens band rules, such as the requirement that CB operators be licensed, it still strictly enforces the ban on so-called linear amplifiers, which can increase the power of a CB signal from the authorized 4 watts to several hundred watts.
