Installed new AtV image today
Set up & reinstalled all the usual stuff

I have 3 tuners & 2 dishes

Tuner C connects to the static dish at 28.2 East
Tuner A & B connect to channel master 1.2 with twin lnb

When its parked up at 28.2 East signal is fine on the 1.2 dish & on the static dish

When moving the dish say to 19.2 East I get no signal from it
The signal from the static dish is still fine

This is where it gets a problem
Ive switch off tuner c in case its causing the problem

So flick through a few transponders on 19.2 East
Some come up with signal & no picture
So do a transponder scan
In comes channels broadcast on Astra 28.2 EAst

How could this be happening?
Tuner C connected to static dish at Astra 28.2 east is off
It would be impossible for even a 1.2 metre dish to tune into a satellite 10 degrees away

Any explanations or remedies?
Ive installed settings again & tried other sats too
