I used gutter pipe (3 by 5 or so) in one band and built one out of brass
@ 2.5 Ghz worked like a champ. Slots were 1/4 wave (freespace) and seperated by 1/2 wave (speed of waveguide, not freespace) How do you figure the speed in waveguide rather then free space? Matt Feed was 1/4 wave sticking into the rect pipe, in the middle. Round pipe should work just fine. |
