The hardest and most important decision in an installation is the location of the antenna.  A good location will provide a 360° view of the horizon
 
On a sailboat the obvious choices are any structure on the stern that will allow the base of the antenna to be 6-8 feet above the deck.   On a power boat a location similar to the VHF antenna will usually do.
 

The graph on the right shows the benefits of the IslandTime HP, coax free installation.
LMR400 is one of the best quality coax used on boats.  It has a loss of 6.6db per 100 feet and a 3db of loss equals about a 50% drop in output power or received signal.

In marine applications with long distances between the AP and your vessel, all loss is important so plan your system to minimize the losses.  Keep your coax run short.

Attenuation Calculator

You can use the Attenuation Calculator to find the loss in a wide variety of coaxial cables.
