Comparing antennas with WSPR

The new end fed antenna has obviously higher signals but also higher noise.
The question is.. which antenna is better?





I now have three antennas that work on 40m (7MHz). The real test of an
antenna, at least on receive, is the signal to noise ratio, and WSPR is a
great way to measure this. I've set up three receivers, with three
computers, all running wspr with the following call signs.
