Re: [HCDX]: Beverage - how long?

["Bill Harms" <wharms@xxxxxxxxx>]

Karel,

	It depends on what you are trying to do. I have tried beverages in 
excess of 2500 meters and my experience says that they are almost too 
directional for most applications.  However, if you are intentionally 
trying to narrow the beam down to pick up stations in a certain 
direction, they fit the bill.  Of course, there is a point of 
diminishing returns. 

	In Utah, I set up a 2500 meter beverage which pointed at Manitoba 
and Minnesota and to points east.  On several channels, at sunrise 
numerous East Coast Daytimers were audible.  On 740, before they 
signed on for the day (This was in the early 80's), I heard the 
station in Newfoundland.  On 730, CKDM was like a local until they 
signed off. CKLG and XEX which were audible on the car radio and 
portables not connected to the Beverage.  Stations to the side of the 
beam were reduced to a point of being barely audible.  I wish I would 
have had more time to make a more comprehensive survey.
