- Page 2 Introduction The DXE-BFS-1 is a single-wire, single direction Beverage Feed System. This W8JI design 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 unit uses an isolated-winding, matching transformer system to significantly increase the signal-to-noise ratio in Beverage and other high impedance antennas.

Page 3: Additional Requirements
20 watts continuously or 200 watts for 5 seconds 400-500 Ω Termination Resistance: Installation We strongly suggest that you read the entire DXE-BFS-1 manual before installing the antenna, and make sure you understand the concepts outlined in the sidebar (below) that are critical to proper operation. Isolation The DXE-BFS-1 operates on the principle of a transformer with isolated antenna and feedline connections. -
Page 4: Performance Factors
1500 watts. Grounding To ground the antenna, run a wire from the – terminal of the DXE-BFS-1 to the ground rod or rods. The antenna system is NOT grounded through the metal case. Feedline terminals are engineered to be ground independent of the metal housing and whatever that housing is mounted on. - Page 5 The antenna can be any length between 3/8-wavelength through multiple wavelengths, although we recommend using lengths similar to those in the table above. In most cases, the DXE-BFS-1 performance is excellent even when the antenna is not cut to the ideal length.

Page 6: Lightning Protection
This unit features small air gaps and wide foil trace areas, as well as entrance gaps at all feed- through terminals. The gaps act as safe, short paths for lightning discharges. The DXE-BFS-1 is normally immune to nearby lightning, although a direct strike might cause component failure. For additional lightning protection, consider using a one-foot link of #26 wire between the antenna terminals and the antenna. - Page 7 Simplified Testing The DXE-BFS-1 feedpoint matching system is not only easy to use, it can also be tested in its operating configuration. Just attach a standard SWR analyzer to test the antenna, the termination and the DXE-BFS-1 as a single entity. Properly functioning systems will show a reasonably constant SWR value over several bands.
- Page 8 Alternate Radio Connection The following diagram shows the DXE-BFS-1 connected to a radio that does not have a Receive Antenna Input. This set up allows switching between a transmit antenna and the beverage antenna using the DXE-RTR-1A Receive Antenna Interface. Refer to the DXE-RTR-1A Receive Antenna Interface manual for more information.

Every effort is made to supply the latest manual revision with each product. Occasionally a manual will be updated between the time your DX Engineering product is shipped and when you receive it. Please check the DX Engineering web site (www.DXEngineering.com) for the latest revision manual. - Page 10 DXE-PSW-12D1A - AC Adapter 12 VDC/1000 mA The DXE-PSW-12D1A is an AC Wall Transformer Adapter to furnish 12 Volts DC at 1000 mA from 110 Vac 60 Hz input, fused output. It features a standard 2.1 mm plug connection for 12 Vdc. Outer connection is GROUND Center Pin is input for +12 VDC.
- Page 11 DXE-RTR-1A Receive Antenna Interface for Transceivers Now you can add a dedicated receive antenna to HF transceivers which lack a separate RX antenna input port - or protect an un-switched RX ANT port on your transceiver! The DXE-RTR-1 Receive Antenna Interface (Patent Pending) is a unique multi-purpose switch unit which automatically or manually switches the RF output antenna connector on any HF transceiver between a separate receiving antenna system and a standard transmitting antenna.
