AV-comm constructions

[MrDish1]

I'm looking for examples of adjustable constructions with an AV-Com

Mvg

 

[ozumo]

Please explain what an "adjustable construction" is. Do you mean an LNB changer or something else?

 

[MrDish1]

Hallo ozumo,

No not a: LNB Changer.
But to run the C-band LNB with a servo engine.
And to let the AV-Commun shift due to; The depth in the scaling.

Prime focus or offset ?

kan alle bij.

 

[MrDish1]

kan alle bij.

can be both

@MrDish1 can you provide some pictures of equipment, such as AV-com and antenna you are going to marry? Or that was only a theoretical question?

 

[MrDish1]

That AV-com is from Wim (Trust) ,and the dish is the 1.84 from Chappie (Chaparral)

Any pictures?

Found wot at this forum from Dreamsat.

I still do not understand where is the problem.... Just take your Av-Com and install it on your dish. Just make sure the phase center of the LNB (Av-Com) is co-located with the antenna's focal point. Very simple.

 

[MrDish1]

Am I talking about a problem.
I do not think so.

 

[RimaNTSS]

So, where is the problem? Can you show it?

 

[MrDish1]

Want to make it so that I can fine-tune the dish in the hobby room downstairs.
I already have qwer and dreamsat as an example of what they have made.

 

[RimaNTSS]

Aw, I see, question is solved and thread can be closed. Even though we miss some real pictures

 

[dreamsat]

please

AV Comm motorized

I only have a 2.20m antenna for the C-band. With this, most C-band transponders can only be received very closely. So I made the LNB rotatable to receive all polarities and it can be moved in the waveguide of the AV-KOMM. With this technology I get up to 2.5 dB more signal on bad transponders...

Thanks! Now it is clear.

And to let the AV-Commun shift due to; The depth in the scaling.

Does the above solution fix the scaling, or just polarity/skew settings ?

 

[MrDish1]

That`s rotate the lnb is clear.
but does is go Up and down in the scalaring that AV-Com.
that is wot i olso wonne now.
Thank you channel hopper.

 

[MrDish1]

It goes up and down, only with which engine I don't know (yet)
