Over and above that, how do I choose a marine VHF antenna?
Marine VHF Antenna Height and Strength A 3- to 4-foot antenna that's 3 dB is generally recommended for boats under 24 feet. Larger vessels can opt for 12- to 18-foot, 7 to 8 dB antennas. “As a general rule, antenna height should be less than half the length of the boat,” Catoe says.
Be that as it may, where do you mount an antenna on a boat? It's best to locate the antenna at least three feet away from any metal objects or other antennas, keeping as much of the antenna above the metal as possible. The extra height above the water will be a plus in the form of additional reception range. HF antennas can be mounted nicely on each side of the pilothouse.
Else, can you use a CB antenna for VHF?
If the cb antenna is an unloaded, full size whip and the frequency of the VHF radio frequency is close to an odd multiple of cb frequency the antenna will show a proper load to the transmitter. The radiation pattern will not be ideal but the antenna will “work".
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.

Hustler Rum-150 with Pl-259 Vhf 148-174mhz Magnet Mount Antenna
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.
Beamwidth is normally measured. 2. at the half-power or -3 dB point of the main lobe unless otherwise specified. See Glossary. The gain or directivity of an antenna is the ratio of the radiation intensity in a given direction to the radiation intensity averaged over all directions.
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.
Does holding GPS receivers close together really interfere with reception? ... Two receivers of the same electrical design could interfere with each other if placed in close proximity since the processing signals from one receiver could radiate from its antenna and cause interference to another.
A CB antenna is for just one band, and that band is for the 11 meter band, and is only sort of near 2 of the Ham bands, and, without modification, will not work on either of them, and most CB antennas are rather lossy as built anyway, so you will not be happy.
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. Handheld radios are carried with you like any other handheld two wayradio or walkie-talkie.
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.
