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.
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.
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
