ok so i realised i didnt understand what andy was saying with the power so i spent the afternoon pulling apart my boot again and running seperate power supply cables to the 2 factory clarion antenna boxes. This works a treat now so when the DVB-T unit is powered up so is the ariels. I also found out the when the Tv board is out of the Gold Casing that it works 100% better (Found this out due to testing when i had to solder the antenna IN back onto the board, totally my doing. IE- dont over tight the ring nuts on these sockets) So i just used double sided tape and put it on the inside of the rear quarterpanel near the original unit.
Commsman- Thank you for all your help with this install. Your information has been spot on and i thank you for that. Also do worry about sending the other unit for testing as i feel confident that i have got it to work as its ment to this time.
