[QUOTE="N1501, post: 794480, member: 385437"] I've only been reading up on Satellite systems/technology for the last 5 weeks and am a complete newb but have managed to get some results as shown here: [URL]http://www.satellites.co.uk/forums/pictures-members-setups-general-satellite-installations/197871-my-first-ever-satellite-pictures.html[/URL] I wanted the best picture quality and assumed that more than one LNB would not be at the true focus of the dish but having just seen a photo of Inverto's Twin HGLN 40mm Black Ultra LNB it seems to have the same "feed horn" size as the unit that I bought so perhaps my original assumption was wrong. I bought the Inverto Single Black Ultra LNB after reading the good reviews about it. I then bought a Vu+ Duo after seeing this post: [URL]http://www.satellites.co.uk/forums/free-air-gems/195907-bbc-mux-27-5w-fta.html#post1014730[/URL] from [COLOR=#008000]Huevos[/COLOR] Now the Duo has two tuners and again I originally assumed that I could only fit one LNB as I had visions of the second tuner sending conflicting signals to the motor control. But after some thought and seeing that Twin and Single LNB's look similar at the feed horn end I would like to know if I set Tuner A to motorised and set Tuner B to single and make sure that it is always set to the satellite that the motor is pointing to ( mostly 28.2E ) will there be any loss in picture quality/perfomance by using a Twin instead of Single LNB, eg noise or crosstalk etc. I know I'll need double the amount of cabling but would then be able to record from a different frequency/polarity whilst watching something else ( albeit from the same satellite ) [/QUOTE]
