OMG! Fatshark clovers are good!

Dusty, you want to eliminate any other chances of noise that might be hampering your video signal first. Getting 400m on 250mW doesn't seem far at all. Try to distance your VTx and antenna from all other equipment (awkward on a Quad I know) or do some ground tests with only the VTX connected and transmitting without the GPS or Rx being powered and see how far you can get. Then turn on each element in turn and do the test again to see what may be causing interference.

Do your tests in an open area, such as a park so that you reduce the chances of other external signals degrading your own Video signal.

Thanks, I'll post a pic of my setup later on but to be honest there isn't much really can be done as you say. The VTx is on the underside of the quad with the antenna bent down at the back at 90 degrees (ish)

I fly at a paintball site I own, here's a vid of the area

There's a whole lot of nothing interference wise :D Brilliant flying playground though. To be fair the setup i have gets good reception all around, just not massive range. You can see the extent of it if you freeze the video at 2.30 that's me at max range where the signal disappeared, not much good to anyone watching who doesn't know the area though!!

When you say ImmersionRC antennas you don`t mean the black straight ones with ImmersionRC written up the length of them do you ?

IE :

I have those which came with the Fatsharks but I use the UFO shaped things which are much better :)

Ok just checking, 400m range seems very low.
