I'm sure this is answered on here hundreds of times so apologies in advance... I want to put up a 40m loop and due to the small size of my yard/garden it will have to be horizontal to fit the space... I know vertical is better for DX but I cant get the height to hang it that way... my question is, when the feed point and the legs are all the same height from the ground and the loop is horizontal does the same rule still apply regarding the feed point as when its vertical, ie fed from corner, side, apex etc to determine the polarization or does it matter as much when all the sides are equal height from the ground? many thanks..

HNY, I didn't see how high up the four corners will be - that will determine alot on how the loop performs. Generally, the horizontal loop will be horizontally polarized and as such does good to quite good
if the lowest operating band is approaching 1/2 wave above average terrain. Additionally, tell us if you can construct a 142' loop (approx 35' each side) - that will make it a full wave on 40 and will be quite beneficial. Generally, you can position the feedpoint anywhere along the loop, but being more specific on the loop typology (and where the shack is located) will help to optimize.
For additional notes, see the "Horizontal Fullwave Loop, Weird SWR Curve" by AK4SK (just updated).
