It depends...... I think George describes the situations well.

What I have experienced, say at VE1ZZ: Jack has Eu Beverages, short, long, 
phased.
He is on the rocky ground, close to salt water bay.

The best Beverage (most of the time) was the long one, going over rocky terrain 
and terminated in the salt water, wire from termination tied to the SS hub cap. 
The wire direction was perpendicular to the water's edge. It beat phased ones 
and short with terminations on land.

Is the salt water the other half of this loooong beverage/dipole? Is there mo' 
better wave tilt from the salt to shore boundary? Is the wire tapping into the 
salt water "plate"?
I dunno, but it works. 

So it appears if we have lousy, rocky, lossy ground on the salty water's edge, 
wire direction is or close to perpendicular and you can terminate it in the 
salt water, that is the winner.
I hope this sheds more light on the "problem" and how to take advantage of 
possible situation and perhaps enhance the Beverages performance. Any more 
experiences?

But.... I think that if one is close to the salt water boundary, couple of 
phased short RX verticals (with some reflectors behind) would outperform the 
Beverages, with less hardware, especially on the isolated beach with no man 
made QRN. That looow Brewster angle just can't be achieved with other tricks.

Happy Easter to all!
