I remeber the lenght of the protected (sheathed) portion of a 2.4 Ghz antenaa is not as critcal as the antenna length itself ( the actual antenna ) . that being said it is critcal that you have the 2 parts of the antenna wire seperated as they do Not connect to the antenna it self in one piece ( you have the inner wire and the protected sheath wire ) . I think your friend made a mistake in cutting these and I would purchase new ones myself .
Or if you must , look closeley at the inner antenna wire and notice that it is soldered to the farthest point ( Of the solder area ) of the antenna and the sheath is soldered in the big dab . . It is critical that these two parts do NOT get soldered together.
I will fully admit I am not an antenna expert and I hope someone with more knowledge can chime in . I just wanted to give you a basic answer and you did not just solder the whire and sheath in a big blob to the antenna itself .
After doing the solder I would take a volt metere and Make sure you have NO continuity beteween the Inner and outer sheath.
****Also one problem is where your friend cut the wire, at that point he may have cripmed the inner and outere wire, or for that matter if in a crash it could be crimped anywhere . You will need to test that out for sure with a voltmeter and you will need to unpug the antenna from the Main mother board it goes to . Like I said I would repalce it .
Also if you notice the length of the antenna is written on the antenna itself at 34.5 MM. Most are between 28 and 32 mm for 2,4 GHZ systems . Once again we are referring to the Antenna itself NOT the COAX going to it .
Once again hoping one of the electronics gurus can chime in , I only have basic knowledge in this .
