Hello?

Where do I get the measures to make the feee horn?

What is the material of the horn feed? Could it be zinc?

Do you have a pdf or video that best explains your hydrogen radio telescope project?

What is the minimum distance between the PC and the antenna so that there is no interference between the equipment?

What materials do I need to build a radio telescope for hydrogen line? What program do I use to obtain and analyze the data?

What is the specimen material inside the feedhorn?

Where can I find the correct feedhorn dimensions I need? I know the dimensions depend on the size of the antenna I will use. What dimensions of the feedhorn, for example, for a 1.5m dish?

What is the material used to build the feedhorn? Aluminum?

Alright, so the engineers built the feed for me:

Might not be a factory-level construction, but I'm very happy for just €35 (he told me the next one would cost €60 because it came out harder than he thought haha).

 

Question: Is it ok if I give it a good white paint (after a layer of primer paint)? I don't think I'll have any problem with reflectivity or something?

Where did you get this equipment built?

Could you tell me what equipment you need to set up a radio telescope? From what I saw in your project I just don't intend to use raspberry pi.

Hello, my name is Gabriel and I'm from Brazil. I would like to build a project to detect hydrogen line with SDR dongle, what materials do I need like LNA, band filters? You said you used line amplifiers, what is their model? What is the order of assembly of the equipment? When I set up my project, could you help me collect and analyze the data?

Thank you  very much

You spoke of a site where you learned a lot, but I did not see any links, could you tell me?

Which site do I get more information about CFRAD?

I am thinking of buying a lna similar to this:

I would like to know what software I can use to make observations besides the radio sky pipe and radio eyes

Besides the dish and bi-square antenna, what equipments did you use in your design like low noise amplifiers, bandwidth filter and etc? I would like more details because I am wanting to build a radio telescope as well.
