Etronix dsss rx losing signal - new antenna?

[almunro]

I think i need to replace the antenna wire on an etronix exg3 pro as it loses signal from the tx around the 25m mark. Never had a problem with it during the few times i ran it indoors but i ran it outside the other day and it activates the failsafe around that mark.

I have read that it may be a low voltage issue with the core/etronix dsss radios, but its at 10.8v which should be fine.

The antenna wire is a bit rough in places, although i cant see an actual cut through or an obvious break. Having a look at the connection of the wire to the rx pcb, its soldered in two spots, one to the internal wire of the antenna, and another part to the wire 'sheath' of the antenna. Is this a must do thing? Can i just replace with a standard piece of wire?

Any advice would be appreciated, as i want to sell it as stick radios arent for me but i dont want to sell on a dodgy piece of equipement.
