Description

BL-154C-3K 4:1 Current BALUN (200:50 Ohms)

The BL-154C-3K is a premium Guanella-style 4:1 current BALUN (200:50 Ohms), expertly designed HF-Log periodic antennas like Cushcraft ASL-2010 and the like, 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 current type baluns available on the market today.

Ideal Applications:

• HF-Log periodic and other antennas with 200-Ohms feed point

• OCF Dipole Antennas with either a 33/67% or 20/80% wire ratio.

Important: When using an OCF dipole,  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.

Unlike some manufacturers, we provide realistic and tested power ratings—our baluns are range-tested to ensure reliability and performance.

Key Features:

• SO-239 PTFE (Teflon) Connector for superior durability and performance

• Stainless Steel Hardware and connecting studs

• Sturdy Polycarbonate Enclosure for long-lasting outdoor use
