Where can I buy a Legit 1420 MHZ Feedhorn for my 2.3m Parabolic Dish?

Hi all.

I'm building a Radio Telescope. I have a 2.3m Parabolic Dish, and I need to buy a Hydrogen Line Feedhorn here in the US, something like THIS ONE

Any help is appreciated.

Thank you

Hi, is there any reason why you can not build one yourself? A cantenna is a very popular linear polarized feed to build in the amateur radio community and is very inexpensive. There are calculators online which will tell you the dimensions and measurments required to build one. Here's an example:

I can build one, but if I can find one that is already made to perfection then I'd buy two.

Yes. That's the one. Thank you

It looks funky in that pic but I can paint it and make it look more professional!
