[Kenwood] your real beam antenna pattern

[TonyG70747@aol.com]

Have you ever wanted to plot your beam antenna pattern quickly for several 
frequencies to find where the beam is tuned for performance and not just a 
good SWR?
Antpat is a special software program that not only allows you to achieve the 
above task but gives you flexibility to use any radio signal source for 
plotting your antenna pattern. The signal source can be RFI, CW, SSB, AM, FM 
etc. There are several software filters that allow smoothing of individual 
patterns, as well as summing, to greatly reduce the normal signal 
fluctuations from the above signals as well as QSB. This allows you to use 
most any station on the air without the need of their being aware of your 
using them as a signal source
These patterns provide you information on:
Testing that new antenna and over time to check for problems (traps , etc.) 
It can be done periodically without generating an on air signal.
Frequency of best beam performance.
Effects on pattern when changing/adding antennas nearby, 
Pattern changing when raising and lowering the antenna.
Your antenna pattern from nearby and DX stations.
Propagation effects on your antenna pattern.
The program allows you to overlay EZENEC (tm) patterns to compare simulated 
patterns to your real beam pattern. This allows you to see the effects of 
propagation as well as comparing to expected performance.
The program requires a simple circuit attached to you S meter circuitry and 
your computer. A fast computer is not required.
Go to http://hometown.aol.com/azantennas for more information real patterns 
and download a demo copy. The program is cheap and you will be surprised at 
the information you can glean from your real antenna pattern.
