okay I understand why a tvLINK eye is used. I have made two drawings for you. The first one assumes that two decoders can be connected to one Unicable port via a normal splitter, but I must tell you this is a very unorthodox way of doing it. The second is using an LMX 501 SLNB. This option will work. Both setups require diplexers behind the Explora 1 and the HD decoder. There is no other way, as neither the Explora 1 or the 4U decoder can receive HB via the Unicable port on the decoder, only via the RF ports. Please PM me an email address. I don't want to attach the diagrams to a message on the forum.
