Title: 2.4 Ghz Receiver Antenna Post by: Mjet on January 30, 2013, 02:34:26 PM Hello All,
In my 2.4 GHZ receiver, antenna wire got a cut on outer wire and have range issue ( not working beyond 100 meters) Antenna wire – COAX, Dipole type Length of Antenna – 14 Cms ( from tip to PCB) Pl suggest, that how can I repair it. Thanks and Regards Mohan Title: Re: 2.4 Ghz Receiver Antenna Post by: sanjayrai55 on January 30, 2013, 02:43:38 PM Mohan
It's best you order a new one. BTW, the length is calibrated in the factory for maximum range Title: Re: 2.4 Ghz Receiver Antenna Post by: Mjet on January 30, 2013, 04:21:23 PM sir,
Buy new antenna or new receiver ? receiver may be ok . Title: Re: 2.4 Ghz Receiver Antenna Post by: sanjayrai55 on January 30, 2013, 04:28:14 PM Which make is it?
If branded, try for antenna alone. Otherwise, you judge: there might not be too much price difference Title: Re: 2.4 Ghz Receiver Antenna Post by: Mjet on January 30, 2013, 04:30:55 PM I have fly sky 9 channel receiver.

If it is at the tip end of the antenna, it is still repairable or else it is not. If the cut is at the tip end of the antenna. Clip of the antenna wire a mm behind the cut area. Now carefully, preferable under a magnifying glass expose the inner conductor of the wire along with its insulation by using a very sharp blade, taking care there is no nick or cut to the inner wire or its insulation. You have to expose a length of inner wire for 30mm Assuming your inner conductor is approx 24 AWG.

If on the other hand your antenna is cut in the middle then try this http://www.hobbyking.com/hobbyking/store/__16667__FrSky_Receiver_antenna_40_cm.html - assuming your pcb end connector matches - it will work 100 % Title: Re: 2.4 Ghz Receiver Antenna Post by: Mjet on January 30, 2013, 05:32:52 PM antenna has Cut at , where wire comes out from plastic casing of RX ( apx 2 cms from solder at PCB) , rest of the wire including dipole + exposed ( 30 mm) with shrink tube is ok.
can i cut the 2 cm piece and resolder to PCB with rest of 12 cms length? total length of wire is 14 cm from PCB to tip Pl see the attached , i will post the actual photograph also. Title: Re: 2.4 Ghz Receiver Antenna Post by: sanjayrai55 on January 30, 2013, 05:38:22 PM The antenna in the link proffered by Mr. Sundaram is $ 2.45. Why would you want to risk your model/engine/electronics?

Title: Re: 2.4 Ghz Receiver Antenna Post by: sundaram on January 31, 2013, 12:00:38 AM if it is closer to the Rx PCB then it is prudent to go with what Saikat has suggested. buy an antenna wire with ufl connector.
Though it is not impossible to solder the wire to the PCB it is a very delicate work to be done with experienced hand. it is better to go with replacement antenna wire. |
