I can't see birds that far east, so pardon my confusion.
However, 40°w bird is circular C-band.
The Ck1 and DMX741 can do circular C-band with the dielectric insert.
Whether a 6' dish is large enough, I couldn't say.
However, if you rig an LNBF for circular, it's not optimized for linear.
So you either need
two Siamese twin LNBFs, or another solution.
Getting a Ck-1 or DMX741 to perform well on KU, on a prime focus dish, will require very careful alignment.
Also, due to the limited field of view, it won't see the entire dish.
So an alternative would be a better choice if maximum signal is a requirement.
The simple
GeoSatPro SL1P would perform better.
Yes, the QP
F-031 (
F=Flange to attach to a feedhorn,
H=includes feed Horn) is matched to the prime focus dish with an AF-120 feedhorn, which sells for about $25.
But, if you mount the QPF-031 at the dish's focus, then it's Ku-only.
Lastly, I'm not seeing a lot of use for circular Ku these days...
Might want to rethink or re-describe the goals, and we can maybe come up with ideas more matched to your needs. -
