Extending a 2.4Ghz Antenna

sparkyjack

i have a controller (RX) with a stubby 2.4Ghz antenna  that extends from the fully encapsulated  controller 

However because of the position of the controller, I have intermittent connection from the hand held transmitter

I wish to extend the antenna aprroximately 2 meters so that  the Transmitter has better connection

How do I connect to the bare 30mm existing antenna?

Thank you

Jack

  •   I agree with   that it may not be practical HOWEVER that never stops us from trying.  Your stubby antenna is most likely a helical antenna.  It's probably directly mounted to the top edge of the controller PCB.  There's a long odds chance that it could be connected by a short run of coax.  Anyway... you could replace the stubby antenna with a SMA-RP connector and then have your choice of commercial WIFI antennas or extension cables to WIFI antennas.  "Easier" would be having a pigtail from the controller PCB and just route it out where the helical antenna used to be.  Something like a bulkhead connector would look more polished.

    The bad news is that this all involves opening the case of the controller.  Good luck.
