Hello. I have a Globecast 0.75m elliptical dish that has a LNBF that has its feedhorn in an elliptical shape also. I would like to purchase a Universal LNBF to use with my Globecast dish. I am just wondering that does the Universal LNBF that I want to purchase have to be elliptical in shape to work with my dish or is it fine for me to purchase a LNBF with a round feedhorn? Thank you.
