OK, i've just made a custom antenna for my bit, i got a length of cat 5 network cable and got the blue and green wires out of it, then twisted them together.. it's really heavy atm (making my car wheelstand constantly when i push it back

), so what length should i cut it to? how long is your antenna?
i did blue and green because im thinking of replicating the HKS drag skyline (yes i know it's an R33 not an R34 :P)
