It's all compromise. If you prefer cband, take that feed, if you prefer KU, use that. Using a combined feed compromises your capacity to chase that elusive hard to reconcile low strength transponder.
Hi everybody,
I am just wondering what people think of the reception of the satellite's with a C/KU Universal LNB on a mesh dish. I have always been under the assumption that you need a solid dish to pick-up decent KU reception.
I notice in another thread Leroy uses a C/KU LNB on I presume a mesh dish. Just wondering what people's experiences are? Thanks.

I use a 2.3m mesh and I'm reasonable happy with the results. I can't use it with the optus sats due to their 'skew if' skew though!

Let's lay this speculation to rest once and for all.
The Wavelength Metres for a given Frequency equals Speed of light / Frequency in MHz.
All Antennae designs revolve around this fundamental Fact.
Short form is 300/ Fo MHz x 100 = mm.
For Ku, 300 / 12500 x 100 = 2.4 mm.
For C Band, 300 / 4000 x 100 = 7.5 mm
Any mesh greater than a half wavelength becomes progressively inefficient.
Regardless of any ad hoc anecdotal claims, them's the cold hard facts as confirmed on Antennae Ranges.
