Which balun to use? The hybrid balun promises advantages over both voltage and current baluns by ZS1AN

The Cedevita-20 is a hybrid monoband antenna, the result of merging the radiator of a shortened vertical with one element of a dipole. It fits on most balconies and must be hung from the ceiling. By ik1zyw Paolo Cravero

This antenna looks like an inverted L antenna, yet it is not, it could also be viewed as a 160m off-center fed dipole antenna, it looks more like an end-fed 1/4 wave 160 meter antenna.

Transformers can be used as part of a hybrid combiner or as phase inverters for an RX antenna array.

This project introduces the Loggi, a hybrid antenna merging the wide frequency coverage of log-periodic dipole arrays (LPDA) with the high gain and front-to-back ratio (F/B) of Yagi antennas. Traditional LPDAs span broad frequencies with moderate gain and low VSWR, while Yagis provide high gain and F/B over narrow bands. By analyzing high-Tau LPDA designs, it was found they could nearly match the gain of VHF/UHF Yagis while maintaining excellent patterns, F/B, and front-to-rear ratios (F/R). Optimizing specific elements for target frequencies (e.g., 144.1 MHz) led to the Loggi, which uniquely features all driven elements without passive directors or reflectors. This design effectively functions as a narrowband optimized LPDA, with front elements acting like Yagi directors and rear elements like Yagi reflectors, thus enhancing gain and directional characteristics while retaining broad frequency versatility.

This article details the development of an 80-meter antenna within the confines of a restrictive covenant community. Faced with limited space, the author explores various options before implementing a clever hybrid design: a short 30-foot vertical wire running discreetly down the building's exterior combined with a capacitive top hat installed in the attic. Computer modeling confirmed the superiority of capacitive loading over inductive loading, increasing radiation resistance from 6 to 14 ohms. The perimeter wire top hat, naturally supported by the attic structure, resonates effectively at 3.5 MHz. The system is completed with four buried 60-foot radials installed "after dark" to maintain compliance with community restrictions.

Learn about the design and construction of a hybrid low-pass filter for HF transmitters, specifically tailored for operation in the 6 meter band. The filter utilizes a single elliptic link for high cutoff steepness and deep VHF/UHF suppression, requiring only two standard capacitor values. The article discusses the necessity for improved filtering due to changing technological landscapes and the increasing sensitivity of VHF/UHF radio channels to interference from various sources. Detailed circuit schematics and performance characteristics are provided, ensuring minimal degradation of antenna system VSWR when integrating the filter into the setup.
