ZDIGDTV100 Marine HDTV & FM Amplified TV Antenna

Cable converts NMEA 0183 data to USB for connection to pcs and laptopsProvides bi-directional data and has status LEDsThe above from the Amazon site is all misleading and false info. This is a standard TV antenna and pre-amp and that is all. No NMEA connector or USB only a coax connection.Also after installing I have found that the Pre-amp gain knob does not turn.

I bought this to replace an older large flat dish model that stopped working well (I was only getting a couple of channels). This fit on the same mount and is WAY smaller. I bought the optional connector box that allows two TVs. If you want to hook up your AM/FM radio antenna, the connection box uses a standard coax so you will need a motorola to Coax connector to get it to fit a Fusion or other radio. The connections are simple. If you don't get good signal strength on the TV channels, adjust the knob on the connection box to get the best result for your setup. Now I am getting about 10 channels (depending on where I am) and really good FM reception.

Works quite well, we seem to get twice the stations we used to get - about 25 stations in Nassau county, Long Island. But be warned -- it does not come with a power adapter and so you need to have a 12 VOLT power adapter to work with it. To a big deal but it would be nice if it was clear this was needed and didn't come with the unit.

This is by far the best marine TV antenna I've seen or used! I'm pulling in so many more stations than I've ever seen on our boat!!! I can't recommend it highly enough!!
