[QUOTE="red, post: 53575, member: 181578"] OK, back to this thread... Reading through the link i posted above, i find that polarization is switched by voltage supplied.... so, this is no problem. i'll give the LNB 18V to force it into Horizontal all the time. As mentioned over here: [url="http://www.satellites.co.uk/php-bin/forum/showthread.php?t=26468"]http://www.satellites.co.uk/php-bin/forum/showthread.php?t=26468[/url] i *must* use a fiber-optic segment between the LNB and the receiver(s), so i have to use a single-band LNB. Right now, i'm thinking that perhaps i need a Triple or Quad Band LNB, as described on LNB page i linked above: [color=Red]8) "Tripleband" LNB Normally bolted to separate polariser and feed horn. Works in 2 bands 10.9-11.8 and 11.8-12.75 GHz. Receiver with 0.95 - 2.0 GHz tuner should be used. Noise figures vary. 9) "Quadband" LNB Normally bolted to separate polariser and feed horn. Works in 2 bands 10.7-11.8 and 11.7-12.8 GHz. Receiver with 0.95 - 2.05 GHz tuner should be used. Noise figures vary. [/color] So, if i get one of these that covers the required freqs, i'll have one signal to send down the cable, over the fiber optic and back to the receiver... Since all my channels are on Horizontal, should be no problem to force the LNB to H polarisation with the 18V supplied, eh? I'm a little concerned that it says that they don't normally come in single-unit packages like a typical "universal"...... UPDATE::::: OK, i went and looked at the Pansatusa site [url="http://www.pansatusa.com/product/LNB.htm"]http://www.pansatusa.com/product/LNB.htm[/url] and they don't seem to list any LNB that would really do what i need.... the closest is the PW-5000 Wideband ([url="http://www.pansatusa.com/product/LNB/PW5000.htm"]http://www.pansatusa.com/product/LNB/PW5000.htm[/url]) but even that requires switching to change from low to high... not cool for what i want to do. So, how about this... would it be possible to mount a second LNB on my dish? Or i'll even use a whole second dish with another LNB if i have to (no planning restrictions ;-). The dish i've got is this the F-90U from this page: [url="http://www.pansatusa.com/product/antenna.htm"]http://www.pansatusa.com/product/antenna.htm[/url] except mine has a triangle-braced feedhorn arm. So, what to do?!? UPDATE 2:: I think maybe what i should do is just add a second LNB: [url]http://www.pansatusa.com/product/LNB/PF-7500U.htm[/url] This one is a universal, but without the tone, it will revert to low-band which is what i want. The only question(s) in my mind to making this work are: 1) How (im)possible is it going to be to mount the second LNB on my dish and get a decent signal with it? 1a) i'd rather not use the second dish, give the choice.. 2) Will just Y-connecting the two LNB outputs together result in the right signal range on the cable? ahh.. i think i see... i'm going to have to do a spreadsheet with all the channels i want, and subtract the LO freq (depending on which LNB..) and see if (which!) frequencies conflict... Will this work as long as none of the freqs i care about conflict? Also.. i'm a little bothered by the fact that i've never been able to tune ANY Nova channel... i know my current LNB does not extend down to 10930, Nova's first freq, but why can't i see the stuff on the 11823 and 12169? Do i have to see 10930 first in order to get the range/name/etc of the other channels? This confuses me... And... once again, thanks for read all of this! [/QUOTE]
