Hi again Ghoulie,
Doh...!!
I'm getting confused now mate... it's been such a long time since I last looped-through my TM 5402 HD to my TM 5400 SD
Unfortunately I gave you incorrect information in my last post... I've just tried it and connected my two receivers with a loop-through... and what actually happens is... the 'Slave' receiver (your Freesat TV) will only be able to use the SAME polarization which is being used on the 'Master' receiver (your TM 6902 HD).
Sorry for the confusion mate... but the info is now correct.
Best Wishes,
Zorch
