The RBS-1P allows two Beverage antennas receiving in opposing directions to share the same space. With the RBS-1P, build a 2-wire reversible Beverage antenna system with superior directivity and signal-to-noise ratio, most useful on the 160, 80 and 40m bands. The W8JI design consists of a Feedpoint Unit and a Reflection Transformer.

Use two RBS-1P's with a DX Engineering RLS-2 switch and have four-direction switching using a single feedline.

This system is immune to strong signal overload and core saturation common in multi-transmitter contesting environments, and is used by winning contest stations and low-band DXers.

The RBS-1P has two antenna ports. The standard configuration of the RBS-1P has one port terminated (termination included) so both antennas share a common feedline. Applying negative 10 to 18 Vdc to the feedline switches between the antennas, and the direction of reception. For simultaneous reception from opposing directions, each of the two feedlines can be run to separate receivers.

While the RBS-1P is optimized to use 450 Ω ladder line for the antenna element, the system will work with any 300-600 Ω two-wire line. 450 Ω ladder line as well as high quality "flooded" 75 Ω coax and F type connectors , to ensure a weather-tight installation, are available from DX Engineering and are sold separately.

Features:

• Broad operating range, 0.2 to 30 MHz
• Fully isolated grounds prevent common-mode noise and unwanted signals
• 75 Ω design enables the use of high quality, low cost cable and connectors
• Metal housings used for shielding and improved life

Please note you will need the following items (not included in this package) to install and operate the RBS-1 antenna.:

• Antenna: A minimum of 3/8 wavelength of 450 Ω ladder line.
• Ground rods: Use at least one 5-ft copper rod.
• Feedline Voltage Injector: Negative 12 Vdc or 12 Vac on the feedline needed for direction switching. Use a DX Engineering FVC-1  ($10. 00 Discount on FVC-1 when purchased with an RBS system) or build your own. (schematic in the manual) 
• Insulators and Supports: Insulators and supports required to support the antenna 4-8 feet above ground. Supports can be metallic but the antenna must be insulated.
