NOTE: there is a slight difference between the current version at DXE, 
and the original.,....the orginal has different connections points on 
the external box that installs to the antenna, the DXE version has one 
connection, and uses internal jumpers to select which type of antenna 
you are using.

>I have one of the Bevflex systems deployed as a short beverage.  I have also used it configured as a BOG.   Mine is the version that was marketed by JK Antennas.

>It works as advertised.  Good f/b ratio.  There does not seem to be a reduction in output on the reverse direction.
>
>The main advantage of it is placement of the feedpoint anywhere on the antenna, making it convenient to feed.  You can also change the transformer taps and configure it multiple ways, such as BOG, beverage, EWE etc.   I have not tried it configured as anything but a BOG and beverage.

>I also have 7 other BOG antennas, using the KD9SV transformer, plus a HiZ triangle array.  The Bevflex holds its own with these antennas.   The triangle has the highest output, but at times is more susceptible to noise (power line).  Sometimes the triangle is best, at other times the BOG/Bevflex are the best, depending on condx.

>I can’t keep beverages up in my woods and have given up.  The next time the Bevflex comes down, it will be reconfigured as a BOG again.

>I have my rx antennas configured so that most of them can be combined (phased) through a DX Engineering NCC-1 box.  This works very well, and many times the performance is enhanced when BOG pairs are phased.
