The document provides a detailed guide on modifying an inverted-L antenna to include the 160 meters band. This enhancement allows amateur radio operators to utilize the lower frequency effectively, which is crucial for long-distance communication, especially during the night. The inverted-L design is popular due to its compact size and ease of installation, making it suitable for various environments. By adding top band capabilities, operators can engage in DXing and contesting on 160m, expanding their operational range and opportunities. The guide includes practical tips and considerations for construction, ensuring that the antenna maintains its performance across the extended frequency range. It discusses the necessary adjustments and materials required for the modification, along with potential challenges and solutions. Whether you are a seasoned operator or a beginner, this project can enhance your station's capabilities, allowing for more versatile operations and improved signal quality on the 160m band. -

An Inverted-L with its long leg sloping to the ground. It will still work very good, even if the horizontal wire has to be sloped diagonally to the ground, as long as you have enough horizontal space to keep it at about a 45 degree angle or more from the pole. -
80m Inverted-L Antenna, Base-loaded for 160m antenna. This antenna is not a good DX antenna however within small garden where true DX antennas would be impossible it has performed very well. -
Medium power BMU (Base Matching Unit) intended for 42 foot to 48 foot vertical, sloper, or Inverted-L antennas. -
This article details an Inverted-L antenna design optimized for 160-meter band operation, consisting of a 10m vertical section and a 28m horizontal section supported by Spiderpoles. Despite its relatively low height compared to the wavelength, the antenna has demonstrated impressive DX capabilities, achieving contacts up to 3,453 miles into Asiatic Russia. The system incorporates a Pi-Network ATU at the base for tuning flexibility. While modeling shows a radiation pattern favoring the South, practical operation indicates effective all-round coverage on Top Band.
