sr300 antenna replacement
 

My antenna broke on my sr300 I noticed it is not a coax so would I be able to use wire from a fm receiver?

I believe so, yes. I had to replace a couple of antenna wires on my Spektrum receivers recently, & best I could tell, they're just basic 24AWG wire(which I have easy access to at work, we use it in all colors all the time). I haven't had a chance to test them on a track yet, but I played with on in my VTA car in the street, & I couldn't tell that I had any glitching, & I ran it as far away from me as I could see safely, so I think it's working fine(though I'll be more sure after this next weekend when I can test it at the track)....:cool:

Any wire with the same length and same diameter would fit perfect!

Can anyone confirm or deny these claims?

These comments are correct. There's nothing special about the wire. Use a similar gauge, the same length as the original.
