Coverage on water?

    Has anyone used their phone while fishing off shore? How far out does the
    signal travel without using an external antenna?

    A 200 milliwatt peanut whistle they sell now will go about 3 miles
    offshore before its toast. Damned transmitter has NO POWER, ya know.

    My Motorola TX200 3 watt bagphone will go about 25 miles out sitting
    on top of the bimini top of a sailboat. We go out further, like 80W
    longitude from Charleston to Florida, so I have an 11-element beam
    that gives me about 15 dB of boost in both directions, about 24 watts
    ERP from way out there. I can get 50-60 miles offshore with the beam
    pointed towards land from 55' up the mast. Works great.

    You could get a beam and a 3W linear from:
    http://www.cellantenna.com/
    and should, probably, get similar results on AMPS (analog). AMPS
    users don't share channels with other users like CDMA does. Less
    competition for the channel = less dropped calls and greater range.

    Of course, they don't want you to know that.......(c;

    Of course, *he* didn't want to know that, either, as evidenced by the last
    five words before his question mark.

    The most likely reason he specified "without using an external antenna" is
    that he'll be a guest on someone else's boat and can't very well go running
    a yagi 55' up the mast (if it's even a sailboat; he said fishing, so it's
    probably a powerboat and doesn't *have* a 55' mast).

    Less competition on each channel = more competition for the limited
    channels available on the tower. Having a channel to yourself won't help
    if you can't *get* a channel because the tower doesn't have enough
    capacity for all those AMPS users. ;)

    Depends on where the carriers tower site is and how they have the
    antennas configured. Typicially the carriers use a lot of downtilt on
    coastal sites so the contour is at a constant level at the 2 mile
    coastal boarder before it hits international waters. Of course most
    phones will work way beyond that due to almost nothing blocking the RF
    but they hate to waste that ERP out on the water when they need to
    penetrate the local buildings as best they can.

    As far as saying exactly how far, as with any RF device and where you
    are, YMMV.

    One guy claims 80 miles off the California coast with .2 watts. Using
    special boomer cells where the 34 mile cdma max range timing has been
    altered and using cryogenic front ends for cell sites making them
    super sensitive.

    Hard to believe but, I'm amazed these things work at all...
