Re: Bluetooth USB antenna EXTENDER hack..quick question
one end of the antenna track is usually connected to ground, the other end goes to a cap and then the chip.
you need to cut the antenna and hook your signal & ground wires to the correct sides.
that wire looks too big, it may rip the tracks off the pcb.
you can put the pcb in a metal case like some 22mm water pipe, then put a wifi antenna socket on the end if you want to be neat about it.

Re: Bluetooth USB antenna EXTENDER hack..quick question
Depending on your antenna, balanced/ unbalanced (bal/un=balun). Read pages 24, 25 of datasheet.
Since you are using a coaxial cable, I presume you are still using a monopole antenna, i.e unbalanced, this is why you still need the balun circuitry. Recommend you to attach he coaxial pin according to pic after disconnecting the internal antenna without removing any other component. find a GND and attach the coaxial GND to it. Good luckComment

by ffrlrMorning 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... -
by HondamanRecently 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"... -
