Is there any benefit to using any other type of feed other than cantenna or loop feed for a small amateur radio astronomy dish for hydrogen line work & is there any benefit to adding a sleeve balun on Loop Feed?
Ideally, the loop and dipole feeds should be balanced feed lines. The balund provides the transition
