The 10-meter band is a portion of the shortwave radio spectrum internationally allocated to amateur radio and amateur satellite use on a primary basis. The band consists of frequencies stretching from 28.000 to 29.700 MHz.
"A two-element, three-band quad, with elements mounted only 35 feet above ground, will give good performance in situations where a triband Yagi will not." [12] Shorter boom Orr (1996) [13] shows a 10, 15, and 20 meter, 2 element quad with boom length of 6′10″. Internally stackable
On the two meter band, the most common directional antennas used by competitors are two or three element Yagi antennas made from flexible steel tape. This kind of antenna has a cardioid receiving pattern , which means that it has one peak direction where the received signal will be the strongest, and a null direction, 180° from the peak, in ...
Radio amateurs can build the Hexbeam as a multi-band antenna to cover different frequency ranges. Popular combinations cover 20m, 15m and 10m (3 band) and 20m, 17m, 15m, 12m and 10m (5-band) ham radio bands. Hexbeams can also be built for the 40m and 30m bands. The antenna elements for the lowest frequency band are located at the exterior of ...
An amateur radio satellite is an artificial satellite built and used by amateur radio operators.It forms part of the Amateur-satellite service. [1] These satellites use amateur radio frequency allocations to facilitate communication between amateur radio stations.
The World Administrative Radio Conference (WARC) bands are three portions of the shortwave radio spectrum used by licensed and/or certified amateur radio operators. They consist of 30 meters (10.1–10.15 MHz), 17 meters (18.068–18.168 MHz), and 12 meters (24.89–24.99 MHz).
The experimental Morgenstern German AI VHF-band radar antenna of 1943–44 used a "double-Yagi" structure from its 90° angled pairs of Yagi antennas formed from six discrete dipole elements, making it possible to fit the array within a conical, rubber-covered plywood radome on an aircraft's nose, with the extreme tips of the Morgenstern's ...
As an "all-band" transceiver, the TS-2000 offers a maximum power output of 100 watts on the HF, 6 meters, and 2 meters bands, 50 watts on 70 centimeters, and, with the TS-2000X or the optional UT-20, 10 watts on the 1.2 GHz or 23 centimeters band. The (American version) radio's main receiver covers 30 kHz through 60 MHz, 142 MHz through 152 MHz ...
