W1KM found that out as they didnt work at all stretched over a saltwater 
marsh out on his Cape Cod contest station

A Beverage needs a relatively poor ground to slow down and tilt the incoming 

On my extra poor ground rock pile Im amazed at how well they work once I 
understood the nuances of proper matching and establishing a steady ground 
reference. If I had run a ground wire end to end as some texts state I would 
have lost most of the directivity.
