Quick Answer: How Far Can VHF Transmit?

How many miles can a VHF radio transmit?

MF/HF Radiotelephone 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..

Can VHF talk to CB?

1 Answer. CB or its close relatives fall into the HF frequency range (covering somewhere around 26 to 28 MHz, depending on country), so anything that accurately calls itself a VHF radio will not transmit (and most likely will not receive) CB. … Therefore it cannot receive or transmit on CB frequencies.

How far will a 25 Watt VHF radio 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.

Who uses UHF frequency?

They are used for television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, and numerous other applications. The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz.

How far can a Baofeng reach?

The range of your receiver is a completely different thing. Your Baofeng UV-5R is a transceiver: that is, both a transmitter and a receiver. With a full battery and in full power mode, it will give you a range of about 10–20 km depending on obstacles.

Does VHF or UHF have longer range?

UHF- Ultra High Frequency UHF radio waves are much shorter in length than VHF, measuring around 12 to 24 inches. As a result antenna length is reduced as well as radio range.

Are Baofeng radios being banned?

591 mean that all Baofeng UV-5R and UV-92 radios (which can transmit [on] FRS and GMRS frequencies) will become illegal to buy or sell in the U.S. after September 2019, even for amateur use? To which, Stone replied, No. Those devices to not have Part 95 certification, so they are not authorized for use in FRS or GMRS.

Does VHF need line of sight?

It depends somewhat of what you mean by “VHF”. The frequency range of 30 to 300 MHz that is defined as VHF does not normally support any other propagation modes than ground or surface waves. These are limited to line-of-sight and sligthly beyond using “reasonable” antenna sizes and power levels.

Why are Baofeng radios so cheap?

One of the reasons the Baofeng UV-5R radios may be so inexpensive is they are not aimed at a specific Niche, therefore they save money on big advertisements and promotions like the ham radio equipment manufacturers like Yaesu Icom and kenwood. They also do not test and advance any technology.

Do UHF channels still exist?

These issues are greatly reduced with digital television, and today most over-the-air broadcasts take place on UHF, while VHF channels are being retired. … In 2011, Channel 51 was removed to prevent interference with the 700 MHz band. The US UHF channel map now includes channels 14 through 36 and 38 through 50.

What radio frequency travels the farthest?

If you are speaking of furthest as to the radio waves being received by another station on Earth then short wave or HF, signals in the 3–30 MHz range can travel all around the Earth. The signal will bounce off the ionosphere and back to earth and continue doing this around the Earth.

Why are Baofeng radios being banned?

But if you follow the amateur radio news, the ARRL has recently reported that the FCC issued a Citation and Order for the Illegal Marketing info Unauthorized Radio Frequency Devices against Amcrest Industries LLC, the company the that imports Baofeng Radios into the US.

What is the range of VHF?

Very high frequency (VHF) is the ITU designation for the range of radio frequency electromagnetic waves (radio waves) from 30 to 300 megahertz (MHz), with corresponding wavelengths of ten meters to one meter.

How far will a 5 watt VHF radio transmit?

So according to our rule-of-thumb, 2 people around 6 feet tall using a 5 watt handheld two-way radio, used on flat ground with no obstacles, will have a maximum range of approximately 6 miles.

What’s better VHF or UHF?

UHF Radio Advantages In general, UHF radios are better for indoor use because their wavelengths are shorter and better able to penetrate through steel and concrete. UHF radios broadcast at between 300 MHz and 3 GHz. VHF radio signals tend to degrade more than UHF signals indoors.

Are police radios UHF or VHF?

The Baofeng and similar radios will program any public safety frequency in the VHF (150-174 MHz) and UHF (450-475MHz) bands. … But, the vast majority of US police agencies still operate on radio channels compatible with the little $30 technological wonders.
