I also bought one this year....deployed it as an EWE, as that’s all the room
I have, small lot in a subdivision.....in order to work them you need to
hear them, and once I put that up, I could hear !!! first put up as EU/VK-ZL
and worked several in the DX contest, but when the african dxpedetions were
on, moved it to due east/west., and worked all of them, S01, etc.....front
to back is remarkable on 160, it works ok on 80, (mine was 10ft high and 38
ft long) but really rocks on 160 !!!!, and really cuts down the line
noise/static I normally hear on my transmit Inv L

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.
