Switched out the Norsat dual Ortho setup for a Quadraport prime focus C, Ku LNBF this weekend. After messing around in this hobby for 9 years now, trying offset LNB's and several flavors of BSC621 I'd say the quadraport LNBF is the ideal solution (never tried the Bullseye II). My dual ortho setup was perfectly tuned and pulling in nearly everything a 7.5 foot dish can, so my goal was to adjust the quadraport to the same cband specs and hope the Ku signals would be good enough.

4 outputs C-H, C-V, Ku-H, Ku-V. Two power circuits that need 15-24 V. It is designed for simultaneous reception on large dishes, where the LNBF slides on rails. I had to make my own mounting system from aluminum stock. Not much of a scalar ring. Apparently they are made differently for dishes based on focal point and f/D ratio, I have know idea what mine is set for.
I am using a modified Spaun SMS5802NF Compact 5x8 Powered Multiswitch to combine and power the 4 ports.
Results: Everything on Cband seems to be the same. CBS 29860 HD 422 feeds, everything on Galaxy 16, CTV, NBC/Telemundo, GCI on AMC7. Ku has been quite good. Able to get everything on AMC21 and 97W. I even get good Ku on SES-2, WTTG and LPB, come in.
For the most part all transponders will tune in at one exact spot with the actuator/vbox (C and Ku), but I only have 2 or 3 clicks of leeway (dual ortho seemed to be wider beamwidth, meaning 3-5 clicks of leeway).
To do... investigate more signal across the arc, figure out how to weatherproof and power Spaun switch at dish OR investigate stacking solutions and in house power supply for LNBs. SES cband issues... Also noticing lower than normal Strength reading on certain satellites (not signal / quality), thinking there could be issue with cband noise. EDIT: SES-2 issues were azbox / luken related. Still need to adjust a bit more to get CBS 9/10 transponders. Changing out multiswitch for one with lower noise / weatherproof housing.

. The multi-switch still senses what the receiver wants and switches to the correct LNB.
used waveguide (expensive)! The 18/14 switch can provide the power inside on the bench; and both to all signal amplifications need to travel both pipes (after you use waveguide x 4 and bring the cable to the other 4 lnb's seperating h/v into the 4 selections) is the solution! The 4 waveguides attach to "siphoning waveguide; each a cut of the 4!
