How to enable a full TX coverage on the Yaesu FTDX101D the european version.

This article describes the design and construction of a 4-meter band vertical sleeved dipole antenna, built to complement a newly acquired Yaesu FTDX10 transceiver. The simple yet effective antenna consists of modified coaxial cable housed in weather-resistant plastic conduit, featuring an integrated 8-turn choke coil. Despite common misidentification as an EFHW antenna, this design is actually a sleeved dipole that provides an excellent 50-ohm match across the band, achieving SWR values between 1:1 and 1.1:1. The project demonstrates an economical approach to entering the relatively quiet 4-meter band.

The Yaesu FTDX10 is presented as a compact HF/50MHz 100W SDR transceiver, employing a Hybrid SDR configuration that integrates Narrow Band SDR and Direct Sampling SDR.
