The antenna may not be more than 20 feet (6.1 m) above the highest point of the structure it is mounted to, or the highest point of the antenna must not be more than 60 feet (18.3 m) above the ground (47 CFR 95.408(c)) if installed in a fixed location. [4] CB radios must include AM or SSB modulation and may include frequency modulation. [5]
After the 1973 oil crisis, the U.S. government imposed a nationwide 55 mph speed limit, and fuel shortages and rationing were widespread.Drivers (especially commercial truckers) used CB radios to locate service stations with better supplies of fuel, to notify other drivers of speed traps, and to organize blockades and convoys in a 1974 strike protesting the new speed limit and other trucking ...
An antenna such as the one described above is usable for both local and medium-long-distance communication across a frequency range of about 1:6 . For example, an antenna for the lower portion of shortwave (say, 3–18 MHz) will be roughly 33 m (110 feet) long, with conductors spaced 1 m (3.3 feet). For the higher portion of shortwave (5–30 ...
Omnidirectional antenna unless otherwise specified. A comma after the power indicates sunset. Whatever is after the comma is the night-time authorization, to avoid interfering with other, higher priority stations. Another comma indicates if it's a directional antenna system. DA means the station uses a directional antenna system.
The Adcock antenna array uses a pair of monopole or dipole antennas that takes the vector difference of the received signal at each antenna so that there is only one output from each pair of antennas. Two of these pairs are co-located but perpendicularly oriented to produce what can be referred to as the N–S (North-South) and E–W (East-West ...
WLW was the outgrowth of an interest in radio by Powel Crosley Jr., although information about his earliest activities is limited.Crosley recounted that his introduction to radio occurred on February 22, 1921, when he took his son to the local Precision Equipment Company store to investigate purchasing a receiver.
Antenna reactance may be removed using lumped elements, such as capacitors or inductors in the main path of current traversing the antenna, often near the feedpoint, or by incorporating capacitive or inductive structures into the conducting body of the antenna to cancel the feedpoint reactance – such as open-ended "spoke" radial wires, or ...
USA (August 1973): The Little Wonder TV antenna was recalled by the CPSC. It was one of the earliest recalls of an electronic device. It was one of the earliest recalls of an electronic device. The product connected the antenna terminals on the back of the TV directly to the AC mains.
