Very easy install - integrated GPS antenna and included VHF "patch" coax cable made it easy. Just hook up power to your panel, unscrew the VHF antenna cable from the existing radio and plug it into the transponder, and then use the included patch cable to connect the transponder to your radio. It works exactly like it should, and we feel very safe knowing that we're visible on the displays of the large ships in our area.

True plug-and-play with a critical piece of equipment. No need to purchase the name brand Furuno or whatever systems for hundreds more as this is the biggest maker in the category.
