Great care must be taken in decoupling the feed line from the antenna in the balanced versions of these antennas, although the EWE (being unbalanced) is relatively immune to such problems. This end fed antenna is very efficient. It is my personal favourite of the two, but both antennas are more than capable of providing good DX. This antenna is designed for stations having a difficult time putting a decent signal on 160M from small or CC&R'd lots. Super-Sloper Antenna 44 69.
