[TowerTalk] Beverage Antenna

[Don]

This theme seems to be that a Beverage needs to be low to reduce noise,s 
been stated several times by several different people over time on this 
reflector. Surely a moer scientific study has been done on a Beverage - from 
laying on the ground to some height -  and the results charted showing the 
change in noise.  Just what is the height where the noise factor would 
negate using such an antenna at all. We have all kinds of studies on yagis, 
dipoles, and other antennas on test ranges under differing heights, surely 
there is one on Beverage's and noise.

Length, I think someone also mentioned that exceeding a wavelength doesn't 
achieve anything additional that is discernible. Did I read this right?

I too would like to learn more about Beverage's and don't have ON4UN's book 
in my library.

The noise is mostly locally produced, therefore the lower the antenna, the
less noise pickup.  The distant signal is coming from a slightly higher
angle and, while it will be a smaller amplitude for a lower antenna (less
efficient), it will be proportionally higher than the noise. In other
words, lowering the antenna will lower the noise more than the desired
signal.  The theory behind the operation of the Beverage antenna includes
wave bending which is over my pay grade. (and not entirely believable to
me.)
