DX Engineering TWIG QRP Off Center Fed Dipole Kits

DX Engineering TWIG QRP Off Center Fed Dipole Kits provide everything needed to build lightweight, low-power (QRP) Off Center Fed Dipole (OCF) antennas around the DXE-TWIG-4-1C QRP Current Balun. Designed for portable operating, these kits make it easy to assemble efficient multiband antennas for outdoor activities such as POTA® and SOTA®, as well as other field and portable operations on the 40 through 10-meter amateur bands. When properly constructed, these antennas are rated for 25 watts SSB, 10 watts CW, and 5 watts digital modes.

At the heart of these kits is the included DXE-TWIG-4-1C balun, which features a 4:1 transformer that converts the approximately 200-ohm impedance of an OCF antenna to the desired 50-ohm impedance required by standard coaxial feedlines. A BNC female connector provides compatibility with recommended coaxial cables and most QRP transceivers. When installed correctly and tuned to the desired operating bands, the included 24 AWG PVC-insulated, stranded copper, high-visibility yellow antenna wire typically eliminates the need for an external antenna tuner. This reduces the amount of gear operators need to carry into the field while allowing for quick band changes and improved operating efficiency.

For best performance, a coaxial feedline with BNC connectors (sold separately) measuring approximately 25 to 35 feet is recommended. These antennas can be deployed in a variety of configurations, with final wire lengths varying based on the installation method and operating requirements.
