A High Gain Mode J/B Yagi Antenna
The actual design was choosen mainly because of its broad 50 Ohm characteristics
A Portable Antenna for Satellites
The Leo Pack is a relatively lightweight circularly polarized antenna system for working satellites using the 2 m and 70 cm bands
A Portable VHF-UHF Roll-up J-pole Antenna
A description is then given on how this dual band principal is applied to a fully portable roll-up J-pole antenna
Adding to an Arrow Satellite Antenna
The UHF section is made of 6 elements with gain-optimized spacing as opposed to 7 elements with equal spacing for the Arrow. This makes my antenna shorter by 6 inches
