Beverage antenna notes

A Beverage antenna transformer, from Clark Electronics, is what you need to utilize your Beverage antenna to its full potential! These transformers are specifically designed for the needs of the Beverage antenna.  They are proven effective in their design and craftsmanship by stations all over the world in a variety of climates and conditions!

What is so special about our Beverage antenna transformers?

Both KB-1 and KB-2 models include:
  • High efficiency ferrite binocular transformers with isolated 50 ohm (SO-239), or 75 ohm (F fitting) primary windings.
  • Low inter-winding capacitance for minimum common noise transfer.
  • Availability in other configurations. (150 to 600 ohm antenna to ground impedance)
  • Very Low VSWR with matched loads taylored for DXing on the low bands.
  • Transformers in attractive, rugged plastic project type boxes.
  • Stainless steel wing nut connections for Beverage wire(s) and ground connections.
  • 50 ohm SO-239, or 75 ohm F coax connectors.
  • Individually calibrated units to eliminate variations found in mass production.
  • Use of adequate core size to prevent saturation from adjacent local stations.
Single wire Beverage.
KB-1 transformer ($ 50.00* with BN-202-73 core plus shipping) Until further notice, comes with a NTE metal oxide termination resistor.

A 450 ohm single wire above ground Beverage antenna transformer uses a binocular ferrite wound core and has a low VSWR into matched loads.

Two wire, two direction Beverage antenna transformer.
Designed to match typical receiving/transmission line and coax cable impedances.  

Combination Beverage 160 meter/HF KB-2, KB-3 antenna transformer pair $150.00* plus shipping.

The two wire, two direction KB-2 uses custom winding for best impedance match possible!

Features of the KB-2

  • Dual direction two wire Beverage transformer has high efficiency.
  • Available 150 to 600 ohm antenna to ground impedance for the antenna wire that is best for your QTH and pocketbook.
  • This system is designed to work with two wire Beverage antennas.
  • T1 binocular wound winding is accurately center tapped for optimum isolation between the two directions.   (The output is wound for 50 or 75 ohms and electrically isolated.)
  • T2 uses a binocular wound input winding and a electrically isolated 50 ohm (SO-239) or 75 ohm (F fitting)output winding.
  • A two wire Beverage sketch is enclosed with each transformer.
  • Two 50 ohm SO-239, or 75 ohm F connectors for coaxial lines to your radio. Termination of the un-used coax is not necessary for good results.
  • Two wire switchable Beverages are described in popular antenna books.
  • For more information check out the "Beverage antenna notes" link on this page.


KB-3 End Termination Transformer !!


  • Wound to the impedance of your antenna for maximum signal recovery.
  • The same quality construction as found in the KB-1 and KB-2 transformers.
  • Transformers are housed in attractive, rugged plastic project type boxes.
  • Wing nut connections for Beverage wires and ground connection.
  • Rust proof hardware (stainless steel).
  • Designed to maximize your front to back gain !

All models are developed and produced in Belfast, Maine, USA.
