Topband: Rx Antenna System

[Charlie Young]

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.

Has anyone had experience with this system and have done a comparison to
other receive antennas? I have room to put up a BOG about 200' long at a
right angle and about 100' away from my present BOG. But it would be
difficult to get the feedline to either end of the wire. This system looks
like I can put the feed point near the center and get selection of either
direction. I can run RG6 stapled to the grass both for the feedline and for
the BOG.

By the way my present BOG is sometimes better than my Pennants and sometimes
the Pennants are better. Wish I had the room for a beverage.
