I bought an antenna at radio shack for my Raython 45. My reception is fair and only at a distance of two miles or so. Is the a big difference in antenna's out there, and if so what would you recommend.

Jason, in my experience you will have some minor differences in signal clarity depending on your location. For the most part on open water you should get very good signals on strong channels. I only have experience with the Shakespeare antennas, but in my opinion they are the best. They offer a myriad of styles and lengths from a $19.99 4'er to a $499.99 21'er. Check out Boatersworld. com, they have a great selection of electronics at great prices.

Any of you big water guys out there have anything else to add? I am by no means an expert. EJ

I live live in Florida most of the guys offshore get their antennas as high as they can. The guys running the flats ie boats low in the water tend to use the short wire powered antennas and put them on the console or poling platform to get a little more height.

Jason,
A couple common culprits for crappy MBR reception:

- Keep the antenna wire as far from any other wiring or transdeucer cables as you can.

- Wire the MBR direct to the battery rather than through a switch panel if possible. Don't forget breakers though.

- Solder the connections between the antenna and the radio. This is a big one. Don't butt splice or crimp - solder. Solder it, put liquid electrical tape on it, and then shrink tube it. Makes a big difference.

Cheers,

Jason,

Another thing to consider are your SWR's (signal to wave ratio) As a general rule the length of your RG cable that runs to your antennae should be divisible by 3. Which battery is your radio powered by? It should be isolated as much as possible. Commercial filters work pretty good.
