Description

Introduction

The Elecraft BL2 is a ruggedized general-purpose wideband balun that can be configured as either a 1:1 or 4:1 balun by means of a slide switch. It is intended to match balanced feed lines to the unbalanced antenna connection of an Elecraft or other manufacturer’s transceiver or antenna tuner.

Overview


OVERVIEW

Our highly efficient balun can handle up to 250 watts and can handle 1:1 and 4:1 ratios via an onboard switch. It is very small (just 1.5 x 3") and lightweight, making it an excellent choice for both home and field use. It uses a special winding technique to reduce losses and extend the useful range, resulting in an SWR of less than 1.2:1 from 500 kHz to 55 MHz (200-ohm load). It includes rugged screw terminals for the balanced output as well as ground and can be used in a variety of matching applications.

Note: This product is a kit that may involve building the product by selecting individual components, soldering them to the circuit board, winding toroids, installing LEDs and displays, calibrating circuits to meet specified performance levels.
