Trying to make radio telescope from easy stuffs

[Shaik Samad Pasha]

Hi everyone!

After my Horn Antenna (CHART-21), I tried making a parabolic - I was busy with my academics and I didn't have any money so I made them with stuff I already have.

I made a Loop antenna (Alex one) as a feed for my parabolic (1.2 meters) and also loop yagi (5 elements - for good impedance i arranged two loop elements near - simulated in feko)

I used cardboard sheet to make the parabolic shape and used aluminium foil.

I got this results - (RFI and some reflections too). i observed this on diwali (festival in India)

Later with the same loop antenna tried a small loop yagi

 

got this results

Let me know your thoughts.

Hello Shaik,

WELCOME to the Group.

Here are some ideas for more advanced Antennas and  H Line Signal Processing  

( simple Windows based sequence  )

The Yagi was  Developed and  Modeled with 4NEC2 and field Validated ..

The NEC model has over 800 elements 

( an example the element listing )
