Description

These PCBs are for Bi-Directional beverage antenna with 1 coax output. 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.


Using

  • Low band receiving antenna
  • For LF, MF and HF SWL
  • Lower noise, better directivity
  • Can be part of phased array

Main functions

  • Broadband 0.2 to 30 MHz (optimal 0.2 to 14 MHz)
  • Bi-directional (reversible) beverage antenna
  • Low noise
  • Very good F/B ratio
  • Twinlead or open wire line
  • 50/75 Ohm feed line version
  • Isolated ground to prevent common-mode noise
  • Electrostatic and HV protection with neon lamps (> 65V AC)
  • One coax version: controlled over the coax feed line
  • ONLY PCBs

Parameters

  • Coax impedance 50 or 75 Ohm
  • PCB size feeder 95x40 mm, terminator 50x33 mm

Available as

KIT: all parts + PCBs and IP56 boxes - KIT VERSION
ASSEMBLED CLASSIC: ready to use - CLASSIC VERSION
ASSEMBLED BOG: ready to use - BOG VERSION
