    hey everyone. I have a Bluetooth device connected to my stereo that receives signal from my phone so I can play music through it. the range is bad so I wanted to put an antenna on it in place of what is there now. but when I opened the case and examined the circuit board I don't see anything that looks like the antenna. can you take a look at this video or pictures here and tell me where the antenna is? the device is called rocketfish.

    the antenna is the rectangle on the lower right corner of picture 1713, the one with the crosshatches on it.

    Thanks! if I was going to solder to it would I scrape away the top layer of sealer and solder away? I can feel it but its not bare wire

    if I ere going to couple the antenna out, I would make a loop of wire to couple the rf out. the less cutting on the circuti board the better, it might change the frequency of the blue tooth transmitter to modify the actual pc board.
