Not true. Even horizontally polarized antennas gain from the salt water. Besides enhancement from the ground, reflection conditions in the immediate vicinity of the array, signals at the salt water edge are enhanced regardless of polarization.

IMHO it is waste to build Yagis for 160/80, Quad is mechanically simpler and electrically superior.

So we are trying to compare 1 - 4 el V array vs. 4 H stack of 10 - ?? elements?

Another big benefit of the salty beach is that there are no noise sources out there, S/N is superior over inland infested by dimmers and plasmas.
