How do they behave if the RX connections are at the centre of the run?

The root beverage design at VP6DX was the DXE reversible hardware & 450 ohm
ladder line. Worked flawlessly. I have used the DXE hardware in other
applications and its the closest Ive found to playing as advertised.
Beverage lengths between 500 and 1200 ft at VP6DX. the phased 800 footers
toward Eu played very nicely.
Consider - the local background noise at VP6DX is as close to zero as it
gets. All noise was propagated noise. The beverages DRASTICALLY out
performed listening on the TX Omni. This means ALL the work is being done
by directivity- (in both planes), and the beverages clearly have the
directivity.
Bottom line rule. ANY beverage is better than no beverage. Trees, bends,
short, long, single, double, Build it and use it.
I really don't like the term reversible. The antenna array is NOT
reversible, it is a two direction antenna array - not bi directional- it is
two directive arrays in one assembly. How you use it is up to you- two
feedlines and hook the two lines to the two receivers in a K-3 and you have
long and short path at the same time, and there are MANY other useful
combinations.
