What channel must you monitor with a VHF radio?
channel 16VHF Marine Radio Channels You won’t be using the vast majority of channels on your VHF.
However, channel 16 on your VHF radio is probably the most important.
Channel 16 is designated as the national distress, safety and calling frequency.
All vessels should monitor this channel while underway..
What is the major limitation of VHF radio?
Their range is further limited by their inability to pass through hills or large structures. Accordingly, VHF waves are limited to use in short-range, line-of-sight communications, including radio and television broadcasting, and in electronic navigation systems.
How far will a 5w VHF radio transmit?
Car, Boat, & Other Radios (Mobile & Fixed-Mount)Average Range Guidelines *WattageFlat Open Terrain (miles)Inside Buildings (floors)4 watts (HF)5 – 610 – 154 watts (UHF)4 – 625 – 305 watts (VHF)4½ – 610 – 155 more rows
Can I use a VHF radio on land?
No you cannot use it whilst on land.
Is a VHF FM marine radio required?
Recreational boats that are under 65 feet are not required to have a VHF radio. … Although a radio is not legally required, you should have one for safety and convenience. That being said, the rules and regulations around VHF marine radio use for recreational boaters in the United States are confusing, to say the least.
How far will a marine VHF radio 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.
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.
Do police use UHF or VHF?

Is Marine Radio AM or FM?
It uses FM channels in the very high frequency (VHF) radio band in the frequency range between 156 and 174 MHz, inclusive. In the official language of the International Telecommunication Union the band is called the VHF maritime mobile band.
Can I use a marine radio on land?
It is illegal to operate a marine radio on land. There are two basic types of VHS Marine Radios, fixed mount and handheld. Fixed mount radios are installed or mounted in your vessel.
How do I know if my VHF radio is working?
You are encouraged to check your VHF radio by calling the station in your area. When you transmit on its channel, you will hear a recorded response and then hear a playback of your voice verifying that your radio is transmitting, modulating and receiving.
What should I look for in a VHF marine radio?
Look for a waterproof radio or GPS rated to the IPX7 standard. Leave any touted as “water-resistant” on the shelf. The man-overboard implications of nonfloating marine electronics should be obvious. Waterproof is nice — so long as you only drop your handheld VHF or GPS in warm, clear, shallow water.
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.
Is VHF or UHF better?
In general, UHF radios are better for indoor use because their wavelengths are shorter and better able to penetrate through steel and concrete. … VHF radio signals tend to degrade more than UHF signals indoors.
Is VHF an FM?
VHF- Very High Frequency Very high frequency is commonly used for FM radio broadcast, two-way land mobile radio systems, long-range data communication, and marine communications, just to name a few. VHF includes radio waves from 30 MHz to 300 MHz.
When can you use a VHF radio?
Use a VHF Marine Radio for Emergencies on the Water: When a Mayday is sent out via a VHF radio it is a broadcast to Coast Guard radio stations as well as any VHF-equipped boat within listening range. Nearby boaters can often offer immediate assistance long before a Coast Guard vessel or towing service can arrive.
Why is the height of a VHF radio important?
Height. In general, the higher the antenna, the better the range of your radio. VHFs transmit via “line-of-site” radio waves–therefore the higher the antenna, the farther your signal will reach over the horizon.
Can UHF and VHF radios communicate?
It is not possible to match UHF and VHF frequencies, because UHF radios only communicate in UHF 430-470 MHZ range and VHF radios communicate in VHF 150-174 MHZ range.
