I used an EFHW sloper on 60 meters using a 49:1 transformer at the feed point that was at 7' and the far end of the wire (88') was 70' high in a tree. Radiation was somewhat directional toward the feed point which was pointed toward the west. But it did give good all around coverage too and had a flat swr of about 1.2:1 on all 5 channels.
