Bi-Directional beverage BOG antenna 2 coax outputs

1 Review

This two coax output beverage antenna has got two output connectors with opposite directions at the same time. It is ideal for SO2R or MM as antenna direction sharing.

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
BOG construction - antenna element on the ground
50/75 Ohm feed line version
Isolated ground to prevent common-mode noise
Common-mode coax choke at output included
Two direction = two coax outputs, each direction is one output
Electrostatic and HV protection with neon lamps (> 65V AC)
Current protection (100 mA) in antenna element
Stainless screws and nuts
High quality connectors
IP56 boxes - recommended to protect it against water
Feeder size 100x100 mm
Terminator size 64x58 mm
ASSEMBLED and TESTED VERSION

Parameters

Feed line impedance 50 or 75 Ohm - version depends on order
Antenna impedance - assembled version: 75, 150, 450, 600 (two wires) Ohms
Common-mode choke isolation more than 30 dB
Current protection (100 mA) and Voltage protection > 65V
Antenna element on the GROUND = BOG more info in the article
Two coax outputs for both directions at the same time - SO2R or Multi

Available as

ASSEMBLED BOG: ready to use
KIT: all parts + PCBs and IP56 boxes - KIT VERSION
Connectors: PL SO-239 or F
PCB: only PCBs

Note

Two coax output beverage antenna works right only when both ports are loaded with right impedance on the same band. It means that you CANNOT leave second port open or short! Also if you use the first port on 160 m and the second on 80 m then second port have to have load impedance on 160 m and first port on 80 m.
