This two coax output beverage antenna has got two output connectors with opposite directions at the same time. It is ideal for SO2R or MM as antenna direction sharing.
There are two beverage antennas receiving in opposing directions to share the same space. That provides one of the least expensive and most reliable ways to improve DX capabilities on the low frequencies. The transformer at the end of the beverage is designed to match impedance of the antenna. A two-wire bi-directional beverage requires the antenna element to operate a balanced transmission line. The parallel wire line used to construct the antenna must be excited under near-perfect balanced transmission line conditions.
ASSEMBLED CLASSIC: ready to use
KIT: all parts + PCBs and IP56 boxes - KIT VERSION
Connectors: PL SO-239 or F
PCB: only PCBs
Two coax output beverage antenna works right only when both ports are loaded with right impedance on the same band. It means that you CANNOT leave second port open or short! Also if you use the first port on 160 m and the second on 80 m then second port have to have load impedance on 160 m and first port on 80 m.

No noise on them, but the best was the “diagram”, in my case, if I selected the NA beverage, it eliminates the signals coming from EU, nice F/B of around 20db but better F/S of at least 25/30db!!!!!! Its normal??????? Both of them are about 250m, in the ground just aluminium pipe of around 1m, no radials, the ground was complety wet and mud.
