1. Instead of shaving your LNBF maybe you can try to use other one with smaller feed.
Inverto is manufacturing not bad LNBFs
Inverto.tv
The feeds of silver line are true small (the picture is not showing true).
The better view is here:
Hollex.pl : Single-pojedyncze : Konwerter Inverto Silver Tech Single 0,2dB
The silver line is maybe not the best what we can buy. The satkurier is anouncing in next paper version tests of new inverto black line , which will be true breakdown in LNBF construction .

Multiswitch ... standard will be good too. Lets look here :

The version V2 is especial for diseqc 1.1 users because it is not working with diseqc 1.0. It means you can connect it with standard cheap diseqc 1.0 in cascade. This is 8x4 = 32 LBNFs to connect. This is for wavefrontier and all your rest dishes.
3. Thank you for your comments and pictures. I will buy this dish too , but I have thought which LNBF should I buy to receive sat in 3 degrees space.
I have thought about golden interstar
Hollex.pl : Quad-4 tunery : Konwerter GI-204S Quad Platinum X
but I see now, the feed is too big and max what I can set only inverto or one inverto, one interstar , one inverto ...
The positions like 4w5w or 10e9e are to receive using one LNBF . I think it should have big feed for collect more signal from the dish.
