This is for a standard Kannad 121.5/406MHz 406 AF-COMPACT ELT.
Could be repaired but the price seems to be under £100 – if you can find stock.
Looks like there was a redesign at some point, which is pretty obvious since the thing flexes in flight like crazy.
I wonder if there is a better antenna – the thin wire on this style is bound to break off eventually.
I found a replacement antenna:
Kannad AV200 White WHIP Antenna Low Speed 250 KN
and it is only about £100.
I got the AV200
An interesting old thread above… amazing to see how much the wire antenna bends in flight. No wonder it eventually breaks.
