2.4Ghz arial wire strangeness
#1

I just got this sanwa/airtronics RX
The arial wire doesnt seem right, shouldnt the last apporx 2cm be unshielded or stripped back, as per my other samwa rx that came with the transmitter.
If the whole arial is unsheilded, then ist just far to long for 2.4

No problem. There are receivers with just a normal wire as antenna, this is most of the time a 13 or a 26cm wire.
Most later model receivers do come with a shielded cable of an not important length with a 31mm stripped endtip which is the actual antenna.

So I guess the antennae isnt a tuned length ?
So I could cut it in half, its far to long.

The wave length of 2.4ghz is about 12.5cm, all antenna's are mostly an half or a quarter length of the wave length, with the 2.4ghz the stripped enddtip of 31.5mm it is a quarter. In case of a normal wire they are the wavelength or sometimes dubble the wave length.
