Bi-Directional beverage BOG antenna 2 coax outputs
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.
80.00 € (without tax)
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
- 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.
