    Default Electronics Question - (not lasers)

    don't ask me why etc... its not important

    I need to extend the range on this Motorola mbp36 camera

    from googling I believe its uses 2.4GHz signal

    here are a few shots of the inside and the transmitter unit





    transmitter






    now would extending the aerial help with extending the range?

    Hey Andy

    The best thing you could do would be to replace the antenna with a higher gain one, by the looks of it (and it's a guess) the one incorporated into the unit looks to be something like 2dBi

    So replacing it with a 4dBi omni or better still a directional patch antenna would increase the range (the directional patch would have the limitation that it must be pointing in the direction of the AP but would certainly increase the distance)

    Be cautious though as doing this would void any RF approvals

    The easiest thing to do would be to get a pigtail with a SMA connector crimped on one end and solder it in place of the existing antenna co-ax, then just use an antenna with SMA connectors

    10dbi
    12dbi
    14dbi directional antenna
    It would be nice to replace base station antenna also

    Cool thanks so could I add say 5 metres of cable then a new aerial?

    Then I can relocate the aerial in the loft

    You can can buy antenna with cable, but long cable gives big losses at this frequencies. Bad antenna with a short cable will give better results than a good antenna with long cable. Need take this into account.
