I have the official Sagem HD receiver and card to receive the TNT Sat channels on Astra plus an official swiss card for reception of TSR from Hotbird. Is it possible (with a monobloc LNB for 13°/19.2°) and a viaccess 3 cam to buy a receiver that can view both services?
It is possible to use monobloc only if you install it using the following instructions; you use Monobloc LNB reversed upside down (so you get ASTRA as LNB 1) use 1 cable and 2 receivers looped and the SAGEM should be box No2 but feed from LNB 1 in the monobloc as Astra and the box 1 that will be used for Hotbird should select LNB as Hotbird.
This is a complicated setup. You will probably need an experienced engineer to set it for you.
The reasons; SAGEM HD boxes are not compatible with double LNBs, TNSAT card will only work with the box supplied -it will not work on Viaccess CAMs or any other boxes.
