Multi-LNBF switch and satellite receivers setup

I am sure there must be a 1-3 switch.

Close the extra connection "no.4" with a "F59T-F" connector for the 4-1 /4-4 switch , might not be the best option think 3-1 switch is still a better option.

F59T-F:
F59T F Terminator


Connecting up to 4 dishes to 4 DVB receiver

LNB:
Might be good to get more than 1 lnb maybe 4 "quad" with bracket / holder then you can get close by satellites as well and you can watch several channels from 4 satellites at the same time without moving dish.

Would be nice but not necesary unless you want too.
