    Bluetooth Receiver

    I am making a portable bluetooth box and would like to add bluetooth capability. the simplest way is something like this: http://www.ebay.com/itm/Wireless-USB...UAAOSw1DtXDbZf

    but the thing is not good enough and does not have external antenna capability, which is very much preferred as the box is metal and it reduces the 30' range down to < 3'. besides the 30' range isnt quite enough to begin with. i'd say 100' open air would be good (allows 30' beyond 2 walls).

    So basically i'm asking if anyone has seen a bluetooth audio receiver that is capable of locating it's antenna outside of the metal case.

    p.s. found a possible candidate, if it can be used without complex external circuitry, http://www.elecfreaks.com/store/ultr...04l-p-543.html (hits budget limit)

    If you check this thread on EEVblog you'll see someone has added an external antenna to a bluetooth dongle similar to yours.

      Re: Bluetooth Receiver

      thanks for the link. i've tried to add an antenna to an fm transmitter like this and came up with nothing.

      it looks like he just added the antenna right where it starts, but doesnt remove the pcb antenna? and will it matter if the antenna is a single floppy bit of wire, or should i try to use one from an old laptop, of which i have a few.

      i was thinking maybe mounting an sma connector to the metal case and using a wifi antenna, would this work well?

        Dell 5410 that doesn't have bluetooth enabled,help please
        by ffrlr
        Morning guy's,

        I have a Dell Latitude 5410 that doesn't have bluetooth enabled, by that I mean the internal bluetooth on the wireless card.
        I have removed the wireless card and fitted it into a 5420 which uses the same card, and bluetooth works in that laptop, so I know the wireless card is fine, the one from the 5420 also doesn't have bluetooth available when in the 5410.

        When I go into setup, under wirelsss, the bluetooth option is greyed out, if I look the service tag up on the Dell support page, it seems it was supplied without bluetooth, my question is...

        Single-channel antenna?
        by Hondaman
        Recently I switched from my Gray-Hoverman to the Antennas Direct ClearStream 4 MAX. Seems to work about as well as the old G-H in my attic (one-story ranch home), but the Antennas Direct unit can be mounted outside on my chimney if desired.

        I should mention that I was also using a 29-inch "T" shaped antenna for RF channel 11. I know you're not supposed to use TWO antennas unless they have the same length coaxial cable going into your combiner (and even then there might be problems). So I made sure the cables were equal length.

        Years ago I made a "T"...
