BL-154V-3K 4:1 Voltage BALUN (200:50 Ohms)

The BL-154V-3K is a premium Ruthroff-style 4:1 voltage BALUN (200:50 Ohms), expertly designed for horizontal multiband loop antennas like the MyLoop-330-3K, as well as off-center-fed (OCF) antennas—commonly known as “Windom” antennas. Built with a large binocular core and PTFE (Teflon) wire, this is one of the most robust and efficient 4:1 voltage baluns available on the market today.Ideal Applications:

Horizontal Delta or Quad Loops using a full wavelength of wire for the 80m or 160m band.
OCF Dipole Antennas with either a 33/67% or 20/80% wire ratio.

Important: When using an OCF dipole, a common mode choke is necessary to prevent unwanted radiation from the coaxial cable shield. We highly recommend the CMC-154-3K. In addition, proper grounding of the coaxial shield at the point of entry is required per NEC-810 guidelines. See our About Grounding page for more information.

Performance:

Frequency Range: 1–54 MHz
VSWR: Near-perfect when terminated into a 200-ohm load
Power Handling:
- Rated at 3kW ICAS (Intermittent Commercial and Amateur Service)
- Capable of handling the full US legal power limit (1500W) with ease, and even more under typical conditions.
