Raymarine RAY 210VHF operation manual Grounding

There are several factors to consider in order to maximize the effective communication range of the radio.

•Since VHF transmissions are essentially Line-of-Sight, mount the antenna at the highest possible location on the vessel and free of obstruction in order to obtain maximum range.

•Use an antenna with the highest possible gain characteristics.

•If you must extend the length of the coaxial cable between the antenna and the radio, use a coaxial cable designed for the least amount of power loss over the entire cable length.

•Keep the coaxial cable between the radio and antenna as short as possible.

2.4.5Grounding

While special grounding is not generally required to VHF radiotelephone install- ations, it is a good marine practice to properly ground all electronic equipment to the ship's ground system. The RAY210 can be connected to ground by attach- ing a wire to one of the RF connector screws on the unit's rear panel and then to the nearest ship's ground connection point. The recommended wire to be used for such grounding is #10 AWG.

The RAY210's cabinet was specifically designed and die-cast from aluminum to insure maximum noise rejection from external sources.
