Spektrum SR2000 antenna length?
 
I bought a used SR2000 receiver, and the seller failed to mention it had no antenna. I'm looking for the length of the antenna from the outside of the case to the tip in mm. Also, I think this receiver has a single conductor antenna, and not coaxial, is that correct? Does the stock receiver have 31mm of the shield stripped off the end at the tip like the other DSMR 2.4ghz receivers?

If it is a coax cable it can be any length and indeed a stripped end tip of 3.125mm

there was so little of the original antenna left, it's hard to tell what type of wire it was, but does look like there was only a single solder contact on the board itself which is why I think it might be non-coaxial.

Then de wire should be arround 20cm

Okay, thanks, is that measured from the circuit board to tip?

The SR2000 uses a single-conductor antenna wire (not coaxial). The length on mine is about 90mm.

Beautiful, thanks. Clarification, is it 90mm from the outside edge of the case to the tip of the antenna?

That's the full length, from the PC board.

Got it. Thanks!
