Choosing a Ham Radio - American Radio Relay League


models. You’ll need two types of antenna; a dual-band quarter-wave mobile whip antenna for 2 meters and 70 cm (there are also tri-band antennas that include 6 meters), and a mobile HF antenna. A permanent or magnetic mount with one or more interchangeable single-band HF whip antenna is a good way to try operating from your vehicle.

A six-band, HF Windom antenna - QSL.net


A six-band, HF Windom antenna April, 1997 This Windom antenna was marketed in the late 70's and early 80's as Smithe's Windom. It was designed to cover 80, 40, 20 15, and 10 meters. By serendipity, it also covers the 17 and 2 meter bands. Now, how was a Windom antenna developed? It began with a center-fed, half-wave dipole.

Millimeter-Wave Beamforming: Antenna Array Design …


The first practical analog beamforming antennas date back to 1961. The steering was carried out with a selective RF switch and fixed phase shifters [7]. The basics of this method are still used to date, albeit with advanced hardware and improved precoding algorithms. These enhancements enable separate control of the phase of each element.
