DX Engineering TWIG End Fed Half Wave QRP Antenna Kits include the essential components needed to build a lightweight, low-power (QRP) end-fed half-wave antenna for portable and field operations. Ideal for activities such as POTA® and SOTA™, these kits are designed for quick deployment, efficient operation, and minimal equipment requirements. When properly assembled and tuned, TWIG End Fed Half Wave QRP antennas deliver an SWR of less than 2:1 without the need for an antenna tuner and are rated for 25 watts SSB, 10 watts CW, and 5 watts digital modes.

DX Engineering TWIG End Fed Half Wave QRP Antenna Kits include the essential components needed to build a lightweight, low-power (QRP) end-fed half-wave antenna for portable and field operations. Ideal for activities such as POTA® and SOTA™, these kits are designed for quick deployment, efficient operation, and minimal equipment requirements. When properly assembled and tuned, TWIG End Fed Half Wave QRP antennas deliver an SWR of less than 2:1 without the need for an antenna tuner and are rated for 25 watts SSB, 10 watts CW, and 5 watts digital modes.
At the heart of these kits is a 49:1 transformer that matches the high feedpoint impedance of the half-wave radiator to a standard 50-ohm coaxial feedline. The integrated BNC female connector is compatible with recommended coaxial cables and most QRP transceivers. Once the included antenna wire is properly tuned for the desired operating band, an external tuner is typically unnecessary, reducing pack weight and simplifying field operation. No separate counterpoise wire is required, as the coaxial feedline serves this function when installed correctly.
To simplify assembly and deployment, the kits feature a built-in quick-connect wire terminal designed for use with the included 24 AWG antenna wire. Two end insulators and attachment clips are also included to provide secure strain relief and convenient field installation. A DX Engineering wire winder and reusable Bongo ties help keep the antenna organized and compact when stored or transported.
A typical installation uses a sloper configuration, with the feedpoint positioned approximately 6 to 7 feet above ground level and the antenna wire extending upward to a height of 25 to 30 feet. For optimum performance, a 25- to 35-foot coaxial feedline with BNC connectors is recommended. An optional DXE-LPFC-BNC Feedline Choke installed at the transceiver end of the coax is also recommended to help minimize common-mode current. While the antenna can be deployed in a variety of configurations, final wire lengths may vary depending on the installation method and operating requirements.
User assembly is required. Recommended tools and materials include wire cutters, a tape measure, 3/16-inch diameter rope to hang the antenna, electrical tape, a suitable throwing weight for antenna installation, and an antenna analyzer for trimming and tuning the antenna element to the desired operating band.
