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
- Classic or BOG construction - as you need
- 50/75 Ohm feed line version
- Isolated ground to prevent common-mode noise
- Common-mode coax choke at output included
- Free configuration for your beverage parameters
- Simply transformer calculator
- One coax version with switchable direction by positive voltage (+ 12V or AC) - you can build it also with negative voltage control
- Electrostatic and HV protection with neon lamps (> 65V AC)
- High power protection
- Stainless screws and nuts
- High quality connectors
- IP56 boxes - recommended to protect it against water
- Feeder size 100x100 mm
- Terminator size 64x58 mm
- KIT VERSION
Parameters
- Feed line impedance 50 or 75 Ohm - version depends on order
- Antenna impedance - as you need and calculated
- Common-mode choke isolation more than 30 dB
- Antenna element in the AIR or BOG
- One coax output with internal relay switch in feeder
- Direction switch needs + 12V / 0.1 A (or AC 12V) - switching by positive voltage
- ANT reception: REVERSE direction with 0 V, STRAIGHT with +12 V
