[help] Frigate and antiship missiles, how to survive

[goldorak]

Hey guys I've got a problem. I've been playing lately with the frigate and the one problem I can't seem to come to terms with is the antiship missiles.
When they are inbound to the frigate I just don't have the time to shoot them all down.
I've tired different scenarios, 688i launching 2-3-4 missiles against the OHP at a distance of 10-16 nm and its great if I shoot one down, but the others hit the target.
I've tried a combination of cwis, chaff and flares, going flank and changing course, even using the 76 mm canon and of course the sm-2 but nothing seems to work with 100% reliability. There is not a single defense system on the frigate that has a 360 degree view so when I hear the incoming missiles I have to decide which system I will use to shoot them down. The problem is that none of them is particularly effective. The problem of course is that even a single hit can damage at 100% the frigate.
I've even tried using the helicopter as an early airborne warning system using its radar to identify very early incoming vampires so as to give me the time to react but usualy the missiles appear on the map when very very near to the frigate.
Does the frigate always loose against an opponent launching antiship missiles ?
Some advice is welcome.
