    I may be moving to the country outside of town soon

    Very hilly and I will be in a weak signal area

    My current phones has no connection for an external mag
    mount antenna

    I "think" I could still get a signal with just an
    external mag mount antenna

    Do ANY cell phones have eternal antenna jacks any more?

    Id like to upgrade to Treo 700p

    Yes, many phones do, including the 700P

    it does have an external antenna jack for mag mount
    antenna?!

    That's just fantastic!!

    Yes, but it doesn't care whether you use a mag mount or another
    kind. (:>) You access the external connector by removing the
    the larger of the two little rubber plugs near the antenna and
    plugging the appropriate cable/connector into it. Doing so
    disconnects the internal antenna (well, apparently not a
    very total disconnect-- something like -20 dB, so 1% of the
    power still goes out that way) and routes the cable to whatever you
    have applied externally. Adapter cables to common external antenna
    connector types are available at all the normal places for ~$5.
    However, if you buy an adapter with an antenna, be SURE that the
    antenna really is PCS and not just 850 MHz. At least one vendor
    implies dual-band operation when the antenna they ship is 850 MHz
    only. PCS antennas will have dimensions which are about one half
    those of 850 MHz antennas.


    Now, does anyone know what the *second* rubber plug is covering?
    On my 700P there is a label saying "Palm" in white letters on
    a red background. Is this perhaps for S/W download. Access for
    diagnostic connection or ??? Any guesses?

    Is that back connector designed for everyday use, or is that connector
    there for testing only? For example, on my MM7400, that connector is
    is designed to be a test connection, and it is not designed for
    everyday use. It is very fragile. The company that I frequently by
    antenna accessories from stopped development of an adapter that
    utilized the back connector because the internals of the connector
    would inevitably break if the adapter was not attached very carefully,
    or after repeated use. This would result in a permanently disconnected
    internal antenna. They recommended to me an antenna adatper that
    required unscrewing the internal antenna and screwing in the antenna
    adpater there.

    There have also been other threads here discussing this problem with
    other phones as well.

    I haven't (yet) disassembled the phone but from what I can tell, it is
    a pretty solid connector. I don't have any qualms about using it at
    will. It is certainly more robust than some connectors I've seen on
    WiFi devices and on other phones.

    Perhaps someone has experience with a Treo 600/650 external antenna
    connector and they can share it with us, I suspect that the 700's is
    similar or identical.

    Thanks

    Good info!

    I've been waiting for the local Costco to get the 700p
    in

    Now it sounds like I can actually USE the 700p out in
    country when I move by slapping the external mag mount
    antenna on top of my fridge or something. Agree?

    Dumb question but here goes

    Instead of using an external mag mount antenna to get
    reception wile living in the country

    Does there exist some kind of cell phone "repeater" I
    could buy and install say up high and use my cell phone
    ANYWHERE while outside this small valley?

    I've installed several of the http://digitalantenna.com
    http://digitalantenna.com/cellamprep_DA4000MR.html repeaters. I've only
    tested them out to perhaps 1,000 feet.

    Hey Cowboy,

    Are they any good? What is your opinion? Is it possible for a person to
    purchase a repeater that is very strong like the repeaters that they use in
    airport tunnels?

    They warn you not to attach any antenna to the indoor pickup antenna
    because it might have feedback into the outside antenna, but I have used
    a outside Yagi antenna pointed away from the outside antenna. I placed
    the repeater on the top a rock quarry and pointed the Yagi down into the
    quarry which was a 200 ft. deep pit about a quarter mile long.

    Depends how green, err...small your valley is. But no, I don't think
    you'll get the coverage you're expecting. The repeaters are mostly for
    improving a signal when you are inside a building, not to fill in a
    large area of several acres.

    Tunnels are a different matter. In some cases a Yagi pointed down the
    tunnel and connected back-to-back to another Yagi outside the tunnel is
    effective.

    Oh hell...that's just a shallow gully in the front lawn here in Texas. I
    know it worked all over the fenced in part of my back yard and that was
    about an acre and shielded from the nearest Cingular tower 12 miles away.

    ha

    yeah the actually coverage I need is abt one acre.

    Its just that this acre is way out in country... hilly
    country at that
