I have my outside aerial shared passing through multiple boxes: first to a Hotchip ODT-4000HD, then a Topfield TF5000PVRt, then a Hdium Duo (ie Himedia HD500B), and finally to a Panasonic THP50G10A TV.
All the boxes receive all local digital channels in Adelaide except the Hdium, which receives neither ABC nor SBS. If I plug the aerial into the Hdium first, then the Topfield doesn't get all channels.
I'm thinking of trying a splitter to feed the Hdium separately, as all the other boxes had good reception previously, but am wondering whether the splitter will attenuate the signaland cause problems of its own.
Has anyone encountered similar problems? Any suggestions on how to improve reception (preferably without adding an amp)?
