Topband: Bev-Flex 4 Beverage system

[Charlie Young]

I deployed the JK Bevflex 4 for this winter Topband season.   First deployment was as a BOG, over a rock cliff. This particular location was not conducive to any BOG, so I changed the configuration to a beverage.   I was very pleased with the way the beverage configuration performed.  It was oriented NE/SW.   Although this initial configuration was short, just over 300', the Bevflex 4 compared quite favorably with a conventional 600' NE oriented beverage.   These antennas were spaced far enough apart to phase through my DXE NCC=1 box, and the dual antennas worked quite well.


The front to back ratio was quite excellent on the Bevflex 4, much better than my last attempt at deploying a bi-directional beverage.  There was no detectable difference in the output level of the antenna in either direction.  The feature of being able to feed it at any point in the antenna is very convenient.


Next season I will deploy the Bevflex 4 in a different location E/W oriented, and it will be about 600' long.


Regarding the original question, beverage performance over down sloping terrain, I have had excellent results with beverages and BOGs running down slope. I agree with K3BU's assessment of the downslope effect.

I have already received several e mails since my posting.  The data sheets
and specs are on the JK antenna website.  (jkantennas..com)



Here is a link to a video presentation I did some time back to one of the
local clubs regarding the system.
