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.
