Choosing the right antenna
Gain vs. beam: a 3 dB antenna has a wider signal pattern that keeps working when the boat rolls or heels, which suits sailboats and rough water. A 6 dB antenna concentrates the signal toward the horizon for more range on stable powerboats.
Height is range: VHF is line-of-sight, so mounting the antenna higher does more for range than extra gain. On a sailboat, a short masthead antenna usually outperforms a long antenna mounted low.
Coax matters: RG-58 is fine for short runs; RG-8X loses less signal over longer runs; RG-213 is the choice for long commercial runs. Keep connections dry and sealed.
Confirm your mount has a center cable passage, that 15 ft of cable reaches your radio, and connector compatibility.
