For normal handheld use (at five-watt transmit power), figure on a three-to-eight mile range from a small boat, compared to 15 to 20 miles with a fixed-mount radio (at 25 watt transmit power.)
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.
What is the range of a 6w VHF radio?
Some handheld radios have 6 watts which can reach up to 20 miles in the right conditions.
How far does VHF transmit?
Marine VHF radios work on a line-of-sight basis. That is, they can transmit and receive to and from another antenna as long as that antenna is above the horizon. How far is that? Standing in the cockpit of a boat, the distance to the horizon for most adults is about three miles.
Can I use a marine VHF radio on land?

The vessel’s licence is like a car tax disc, but is also the key to obtaining an MMSI number, which will uniquely identify your vessel.
Can VHF talk to CB?
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.
How far can you talk on GMRS?
GMRS radios with a low optimal range of 10-16 miles typically have basic features and functionality.
