I have a Corona 2.4 receiver of 8 channels (the type with two antennas).

The mesh of one of the cables-antennas seems to be ripped-off, right at the soldered to the board of the RX joint.
The cable-antenna is not cut-off, only the mesh is damaged.
I have to cut about 5 mm (3/16") from the cable for soldering it again.

Is it possible to do this? Do I have to trim back the two antennas to the same length? (I ask this because in the
72 Mhz radios it cannot be done because the frequency varies).

I discovered this problem when I dissembled the receiver, which has had loss of signal for a few seconds.
Could that failure be caused by the defective mesh?

Thank you very much.
