if u are using the lnb for 118/119 not the original dishnetwork lnb.
configuartion: for both 119 and 118.7 lnb frequency is 10750 and same port number . and it's compatible with dp34 or 4x1 switch .
if you are using the original dishnetwork lnb:
119 has an output and 118.7 has an output. each goes for different port. 119---port 1 110-----port 2 118.7------port 3 using dp34. no need to use the power inserter.
The geniric 118/119 have always been available either as one 118/119 output or two 118/119 outputs. The latter version is good for two receivers. The DPP plus LNB comes with separate output for 118 and separate for 119. You have to use a DP34 or DP44 to get the signals to 2-3-4 receivers The generic LNBs can be set up using 10750 for 119, but you may find a displacement of the TP freq by 500. Confusing when you are trying later to get one TP. One generic LNB will get over 600 channels using Universal2 9750-10750 setting. Some generics work better using 10600 LNB frequency.
