Build your mobile antenna which outperforms Hustler by 10db and ATAS-100 by 18db. From 80 to 10m. The HB9ABX mobile HF antenna, designed for 10 to 80 meters, was developed by Felix Meyer and outperforms commercial antennas like HUSTLER and YAESU ATAS-100/120 in field tests. Made from fiberglass rods and enamelled copper wire, it includes a loading coil with adjustable taps for tuning across bands. Installation requires solid grounding, and adjustments are made via whip length and coil settings. An antenna tuner ensures optimal SWR. Users must handle fiberglass with care due to health risks. This design proved highly effective in South America and Europe.

The J-Pole antenna is an omnidirectional antenna that can be used for base, mobile and field day stations. It does not need a ground plane, radials or a complicated matching system. The J-Pole can be cheaply, simply and quickly constructed using a variety of techniques, some of which are discussed in this article.

Delta Loop Antenna for 15m band. This antenna is made for operating from outdoors, mainly from mobile shack. Drive to a parking you like, then build it up. Just half an hour later, you can enjoy slightly better gain than normal dipole.

This project details three variants of a vertical half-wave antenna design for the 4-meter (70MHz) amateur radio band. The antennas use end-feeding with a parallel-tuned circuit for impedance matching to 50-ohm coaxial cable. The first variant uses suspended flexible wire for portable use, the second employs a fiberglass rod with internal wire for permanent outdoor installation, and the third utilizes aluminum tent poles for quick mobile deployment. Despite the narrow bandwidth of the matching circuit, this suits the narrow 4m FM allocation well. The design offers an effective omnidirectional radiation pattern and can be constructed with readily available materials.
