No Adjusting really. The higher the decibel level. The worse the signal is, dish could perfectly aimed and dialed in, but if there are excess barrels, unneeded splitters, un approved connections, bad cabeling. It all adds to signal loss. Alot of time I have seen where a G2 is on a splitter way too big for what it needs or way too much cabeling.
On approved cabeling, approximate loss is about 6 decibels per 100 ft. of cable.
2 dbs for connectors,
4 db for 2 way splitter
7 db for 4 way splitter
14 db for 8 way splitter
So if your ODU is properly installed and dialed in. Depending on what kind you have say your sitting at around 25-27 dbs at the Dish.
100 ft of cable
Couple barrels
A splitter
Without bad connections, old cable, un approved cable you could already be sitting at 32-38 decibels at the G2. Any of the above listed and it climbs. I've seen the Genie 2 start acting up at as low as 42-44 decibels.
I have seen countless times. Where people have gone fr 5 or 6 sd boxes in their homes to a g2 and wireless minis, and no cabeling has been changed. Still passing through the 8 way splitter.
On a G2 system. If the dish is in an area where it allows, I would do a Home Run straight from the LNB to the G2.
Older systems didnt require the quality connections and cable runs the g2 system requires. The higher the db loss. The more it effects certain frequencies passing through.
On your setup. I would have a straight homerun down to your hs17 with a 2 way splitter. To add in the 4k client.
