DX Engineering Reversible Beverage Systems

DX Engineering Reversible Beverage Systems basically allow two Beverage antennas to be switched to receive in opposite directions while sharing the same physical space.

DXE-RBSA-1P Reversible Beverage Systems antennas provide two opposite "end-fire" directional patterns with excellent front-to-rear directivity and superior signal-to-noise ratio as compared to transmitting antennas.

Dramatically improved long distance weak signal results may be achieved on MW and the 160, 80 and 40 meter bands, including shortwave bands, with receive-only Beverage antennas using wires that are typically only 350 to 800 feet long, depending upon the band of interest. The two-direction DXE-RBSA-1P Reversible Beverage Systems offer a space and installation advantage because two opposite single-wire Beverage antennas would require twice the length.

DX Engineering Reversible Beverage Systems are immune to the strong signal overload and core saturation common in multi-transmitter contesting environments and are used by winning contest stations and low-band DXers around the world. These Reversible Beverage antennas have two "F" connectors; one "Away" port for the default end-fire receiving pattern off the end of the wire, and one "Toward" port for the opposite direction. The standard configuration of these systems has the "Toward" port terminated (75-ohm termination included), so both antennas share a common feedline. Applying a negative 10 to 18V DC to the feedline switches the system between the two antenna ports for reception in opposite directions. For simultaneous reception from opposing directions, each of the two feedlines can be run to separate receivers, with the termination load not used.

You can build a 4-direction receive antenna system with two DXE-RBSA-1P Reversible Beverage Systems and one DX Engineering RLS-2 Two-Port Receiving Switch that also requires only one feedline! The optional DX Engineering Feedline Voltage Coupler, model DXE-FVC-1 is highly recommended to provide all of the required feedline voltage injection. Plus, the optional DXE-EC-4 BCD Control Console completes the system for four-direction switching right in the shack.

DX Engineering Reversible Beverage Systems are optimized to use our optional 450 ohm ladder line for the antenna element. We strongly recommend using that type of "window line" because the consistent spacing of the antenna wires will produce the best operational results. However, the RBS will work with any 300-600 ohm 2-wire line. For best feed line results, DX Engineering highly recommends using our high quality flooded or quad-shielded 75-ohm coax with F-type compression connectors to ensure a weatherproof installation.
