hello,
i saw this and will all 4 tv sets pick up the same thing?
if all 4 tv sets will pick up the same pip and the same channels ther here is what you need.
4 satellite receivers with modulators built in 4 output lnb with 4 lines going to all 4 receivers will be siting on different uhf frequencies.
example one channel 21 one on channel23 onr on channel 25 and another ch 27.
loop all the receivers together and run the one line to all tv sets.
if the tv has 4 pip system you can see all 4 in different coners and and just go the screen you want.
now if you want to do all 16 channels all different channels thats different.
you will need a quatro lnb with all seperate outputs.
horz low.horz high,vert lo and vert high. these 4 lines will go to a 16 output multiswitch.
do not make a mistake with any of the 4 lines or it will not work.
horz low line will go to the horz low input of the multiswitch.
all 16 receivers will have its own input and if they have modulators each modularor will be set on a different frequency.
leave one channels spacing on the modulator
you can loop some togeather and you may need a combiner we well.
then a small amplifer and all 4 tv sets will have 16 tv channels each.
considering the cost of 16 digital receivers 50 euro each multiswitch at 150 euro and the lnb at about 50 to 90 euro this some system for the house.
hope this helps
will check mail later tonight
