    I took apaart my 3585i and here's what I found. The only metallic
    contact the external antenna has with the phone, is in the down or
    shorted position, when the external is disengaged. There's no direct
    electrical contact in the up position with the external antenna.
    Appears to be an Inductive type". If there's some gain from the
    external, it's from the proximity of the the external to the other
    receiver components. This is easy to verify by unsnapping the patch
    antenna. There's two tabs, just above the battery. Release and gently
    pry up from the bottom. there's one smaller tab on the left top
    corner.

    One can see the ~35mm GPS antenna segment above the patch cellular
    antenna. Didn't notice any antenna pattern inside the plastic patch.
    The entire silver colered section is mettalic

    The GPS and patch are always connected, at least mechanically. The
    supplied external antenna is looking more and more like a placebo.
    Don't know how the previous poster hooked up their own
    external...there's two small holes in the top of the patch antenna
    part(the 1" metallic coated piece of plastic that snaps out) and two
    large gold contact pins, which press against the circuit board, just
    on the other side.
    If someone could come up with an extra "patch assembly", might be an
    good location for mounting an external antenna connector, without
    having to modify the phone too much. There's quite a bit of space and
    nearby large contact pins for attaching or soldering wires.
    The GPS antenna is located on the same part. It's a ~35mm metallic "L"
    strip.

    There's also another "test port", next to the earpiece, on the screen
    side of the phone, visible when the faceplate is removed.

    Of course it would be much simpler, if Nokia/Verizon had just included
    an antenna connector/contacts, either in the bottom of the handset
    (still hoping one gets discovered there) or in the usual Nokia 51-61xx
    position.

    I do not understand how a patch antenna works. There's no familiar
    antenna shape, just a rectangular, metallic coated, piece of plastic,
    with bare line in an "L" pattern running part way across th patch.
    Wonder if the patch and receiver design are optimized for each other?
    There's some reason supplied external antenna isn't even hardwired to
    the phone?
    Do other Nokia patch antenna handsets have ext connecters?

    Still want to hook up a Yagi to this phone and see how much
    improvement in fringe area D/A reception is possible.

    I do not understand how a patch antenna works. There's no familiar
    antenna shape, just a rectangular, metallic coated, piece of plastic,
    with bare line in an "L" pattern running part way across th patch.
    Wonder if the patch and receiver design are optimized for each other?
    There's some reason supplied external antenna isn't even hardwired to
    the phone?
    Do other Nokia patch antenna handsets have ext connecters?

    Still want to hook up a Yagi to this phone and see how much
    improvement in fringe area D/A reception is possible.

    I took apaart my 3585i and here's what I found. The only metallic
    contact the external antenna has with the phone, is in the down or
    shorted position, when the external is disengaged. There's no direct
    electrical contact in the up position with the external antenna.
    Appears to be an Inductive type". If there's some gain from the
    external, it's from the proximity of the the external to the other
    receiver components. This is easy to verify by unsnapping the patch
    antenna. There's two tabs, just above the battery. Release and gently
    pry up from the bottom. there's one smaller tab on the left top
    corner.

    One can see the ~35mm GPS antenna segment above the patch cellular
    antenna. Didn't notice any antenna pattern inside the plastic patch.
    The entire silver colered section is mettalic

    The GPS and patch are always connected, at least mechanically. The
    supplied external antenna is looking more and more like a placebo.
    Don't know how the previous poster hooked up their own
    external...there's two small holes in the top of the patch antenna
    part(the 1" metallic coated piece of plastic that snaps out) and two
    large gold contact pins, which press against the circuit board, just
    on the other side.
    If someone could come up with an extra "patch assembly", might be an
    good location for mounting an external antenna connector, without
    having to modify the phone too much. There's quite a bit of space and
    nearby large contact pins for attaching or soldering wires.
    The GPS antenna is located on the same part. It's a ~35mm metallic "L"
    strip.

    There's also another "test port", next to the earpiece, on the screen
    side of the phone, visible when the faceplate is removed.

    Of course it would be much simpler, if Nokia/Verizon had just included
    an antenna connector/contacts, either in the bottom of the handset
    (still hoping one gets discovered there) or in the usual Nokia 51-61xx
    position.

    I do not understand how a patch antenna works. There's no familiar
    antenna shape, just a rectangular, metallic coated, piece of plastic,

    Of course it would be much simpler, if Nokia/Verizon had just included
    an antenna connector/contacts, either in the bottom of the handset
    (still hoping one gets discovered there) or in the usual Nokia 51-61xx
    position.

    I do not understand how a patch antenna works. There's no familiar
    antenna shape, just a rectangular, metallic coated, piece of plastic,
    with bare line in an "L" pattern running part way across th patch.
    Wonder if the patch and receiver design are optimized for each other?
    There's some reason supplied external antenna isn't even hardwired to
    the phone?
    Do other Nokia patch antenna handsets have ext connecters?

    Still want to hook up a Yagi to this phone and see how much
    improvement in fringe area D/A reception is possible.

    I took apaart my 3585i and here's what I found. The only metallic
    contact the external antenna has with the phone, is in the down or
    shorted position, when the external is disengaged. There's no direct
    electrical contact in the up position with the external antenna.
    Appears to be an Inductive type". If there's some gain from the
    external, it's from the proximity of the the external to the other
    receiver components. This is easy to verify by unsnapping the patch
    antenna. There's two tabs, just above the battery. Release and gently
    pry up from the bottom. there's one smaller tab on the left top
    corner.

    One can see the ~35mm GPS antenna segment above the patch cellular
    antenna. Didn't notice any antenna pattern inside the plastic patch.
    The entire silver colered section is mettalic

    The GPS and patch are always connected, at least mechanically. The
    supplied external antenna is looking more and more like a placebo.
    Don't know how the previous poster hooked up their own
    external...there's two small holes in the top of the patch antenna
    part(the 1" metallic coated piece of plastic that snaps out) and two
    large gold contact pins, which press against the circuit board, just
    on the other side.
    If someone could come up with an extra "patch assembly", might be an
    good location for mounting an external antenna connector, without
    having to modify the phone too much. There's quite a bit of space and
    nearby large contact pins for attaching or soldering wires.
    The GPS antenna is located on the same part. It's a ~35mm metallic "L"
    strip.

    There's also another "test port", next to the earpiece, on the screen
    side of the phone, visible when the faceplate is removed.

    Of course it would be much simpler, if Nokia/Verizon had just included
    an antenna connector/contacts, either in the bottom of the handset

    The GPS antenna is located on the same part. It's a ~35mm metallic "L"
    strip.

    There's also another "test port", next to the earpiece, on the screen
    side of the phone, visible when the faceplate is removed.

    Of course it would be much simpler, if Nokia/Verizon had just included
    an antenna connector/contacts, either in the bottom of the handset
    (still hoping one gets discovered there) or in the usual Nokia 51-61xx
    position.

    I do not understand how a patch antenna works. There's no familiar
    antenna shape, just a rectangular, metallic coated, piece of plastic,
    with bare line in an "L" pattern running part way across th patch.
    Wonder if the patch and receiver design are optimized for each other?
    There's some reason supplied external antenna isn't even hardwired to
    the phone?
    Do other Nokia patch antenna handsets have ext connecters?

    Still want to hook up a Yagi to this phone and see how much
    improvement in fringe area D/A reception is possible.

    I took apaart my 3585i and here's what I found. The only metallic
    contact the external antenna has with the phone, is in the down or
    shorted position, when the external is disengaged. There's no direct
    electrical contact in the up position with the external antenna.
    Appears to be an Inductive type". If there's some gain from the
    external, it's from the proximity of the the external to the other
    receiver components. This is easy to verify by unsnapping the patch
    antenna. There's two tabs, just above the battery. Release and gently
    pry up from the bottom. there's one smaller tab on the left top
    corner.

    One can see the ~35mm GPS antenna segment above the patch cellular
    antenna. Didn't notice any antenna pattern inside the plastic patch.
    The entire silver colered section is mettalic

    The GPS and patch are always connected, at least mechanically. The
    supplied external antenna is looking more and more like a placebo.
    Don't know how the previous poster hooked up their own
    external...there's two small holes in the top of the patch antenna
    part(the 1" metallic coated piece of plastic that snaps out) and two
    large gold contact pins, which press against the circuit board, just
    on the other side.
    If someone could come up with an extra "patch assembly", might be an
    good location for mounting an external antenna connector, without
    having to modify the phone too much. There's quite a bit of space and
    nearby large contact pins for attaching or soldering wires.

    If someone could come up with an extra "patch assembly", might be an
    good location for mounting an external antenna connector, without
    having to modify the phone too much. There's quite a bit of space and
    nearby large contact pins for attaching or soldering wires.
    The GPS antenna is located on the same part. It's a ~35mm metallic "L"
    strip.

    There's also another "test port", next to the earpiece, on the screen
    side of the phone, visible when the faceplate is removed.

    Of course it would be much simpler, if Nokia/Verizon had just included
    an antenna connector/contacts, either in the bottom of the handset
    (still hoping one gets discovered there) or in the usual Nokia 51-61xx
    position.

    I do not understand how a patch antenna works. There's no familiar
    antenna shape, just a rectangular, metallic coated, piece of plastic,
    with bare line in an "L" pattern running part way across th patch.
    Wonder if the patch and receiver design are optimized for each other?
    There's some reason supplied external antenna isn't even hardwired to
    the phone?
    Do other Nokia patch antenna handsets have ext connecters?

    Still want to hook up a Yagi to this phone and see how much
    improvement in fringe area D/A reception is possible.

    I took apaart my 3585i and here's what I found. The only metallic
    contact the external antenna has with the phone, is in the down or
    shorted position, when the external is disengaged. There's no direct
    electrical contact in the up position with the external antenna.
    Appears to be an Inductive type". If there's some gain from the
    external, it's from the proximity of the the external to the other
    receiver components. This is easy to verify by unsnapping the patch
    antenna. There's two tabs, just above the battery. Release and gently
    pry up from the bottom. there's one smaller tab on the left top
    corner.

    One can see the ~35mm GPS antenna segment above the patch cellular
    antenna. Didn't notice any antenna pattern inside the plastic patch.
    The entire silver colered section is mettalic

    The GPS and patch are always connected, at least mechanically. The
    supplied external antenna is looking more and more like a placebo.
    Don't know how the previous poster hooked up their own
    external...there's two small holes in the top of the patch antenna
    part(the 1" metallic coated piece of plastic that snaps out) and two
    large gold contact pins, which press against the circuit board, just
    on the other side.

    external...there's two small holes in the top of the patch antenna
    part(the 1" metallic coated piece of plastic that snaps out) and two
    large gold contact pins, which press against the circuit board, just
    on the other side.
    If someone could come up with an extra "patch assembly", might be an
    good location for mounting an external antenna connector, without
    having to modify the phone too much. There's quite a bit of space and
    nearby large contact pins for attaching or soldering wires.
    The GPS antenna is located on the same part. It's a ~35mm metallic "L"
    strip.

    There's also another "test port", next to the earpiece, on the screen
    side of the phone, visible when the faceplate is removed.

    Of course it would be much simpler, if Nokia/Verizon had just included
    an antenna connector/contacts, either in the bottom of the handset
    (still hoping one gets discovered there) or in the usual Nokia 51-61xx
    position.

    I do not understand how a patch antenna works. There's no familiar
    antenna shape, just a rectangular, metallic coated, piece of plastic,
    with bare line in an "L" pattern running part way across th patch.
    Wonder if the patch and receiver design are optimized for each other?
    There's some reason supplied external antenna isn't even hardwired to
    the phone?
    Do other Nokia patch antenna handsets have ext connecters?

    Still want to hook up a Yagi to this phone and see how much
    improvement in fringe area D/A reception is possible.
