Question
What are the dimensions of your rectangular to circular feed shown with the ferranti x band LNA.
Is the 28mm inside or outside diameter. What is the length of tube sections or dont it maatter
Thanks Dave Dwyer ZL3TKR
Dave, The ID is 26mm and the OD is 28mm. This is a Vertex LNA. I do have the Ferranti as well but the Vertex is what i currently use.
Where can I get this LNA from and whats the cost as I want to use a 5 foot Siemens solid dish
They are available on Ebay. The cost varies.
