What I can tell you is that my 40m vertical works very well in the directions
where it is over salt water - about 240 degrees through 60 degrees. In fact
modeling would indicate I would need a two element Yagi up about 75 feet or
more to even get close. However, I can put up a dipole at 45 feet and beat
that vertical to Africa or South America by two S units or more - not one of
these comparisons where you switch back and forth trying to convince yourself
that one antenna is better than another but instead an extremely stark
difference.
