Advice Needed Channel Master 1m20 C-band mod

True but I dont like touching elevation controls for obvious reasons, although its just 2 nuts on CM..
 
Well, if you fit a jack on and add another V-Box on top then it will be easier than having to do it manually. Technically the C band LNB will be not be at the dish's focal point but C band is more forgiving than Ku.

Having motorised elevation also means you can fine tune the dish better.
 
Inverting the reflector prevents water from getting in the feedhorn.

You could go 'old style' and find a CoRotor and some flanged LNBs.

You will need a pulse generator to drive the internal motor
 
Speaking about size of clamp for C-band LNB, it should be 65mm (not less), as the majority of C-band LNBs has 65mm neck size. Some LNBs, like Chaparral have even bigger neck diameter.
 
Many thanks for all the feedback.
With the advent of Ka-band transmissions covering our are more and more, it would be nice if someone offered a Ku+Ka band LNB.
Curently, Ka band LNB are very expensive.
I also got hold of a Chapparal borehole C+Sband feed for a 3m parabolic.Seema hard to use it though.

I am already motorised uasing an 18-in arm and Pace 995.
 
There is not much out there on S-band (Es'Hail 2 uplinking)

Es'hail 2 25.8°E channels

How are the beams for the broadcast channels on Es'hail 2 at 26E? Are they as tight as for its sibling at 25.5E? Any reception in Europe other than Southern Europe?

I doubt the Pace has the components to run a mechanical polariser
 
Combi LNB I will have is H/V switching by voltage, for both Ku and C. Not sure it will give optimum performance on C band.
 
The combi LNBs should be OK for C band, it's the Ku frequency that will be lossy.
 
Unfortunately, you may be right .The Chinese manufacturer does not give any technical info on gains or cross-interference etc.
