Diagram of a car undergoing fishtailing. Video of a car fishtailing or drifting on the street of Riia maantee in Tartu, Estonia (December 2021) Fishtailing is a vehicle handling problem which occurs when the rear wheels lose traction, resulting in oversteer. This can be caused by low-friction surfaces (sand, gravel, rain, snow, ice, etc.).
A Motorola connector (also called a Motorola antenna plug [citation needed] or a male DIN 41585 [1]) is a common coaxial cable RF connector used primarily in the automotive industry for connecting the coaxial feedline from the antenna to the radio receiver. It is also sometimes used for connecting scanner antennas to scanners.
A transmatch (antenna tuner) is not required to use this antenna near its nominal design frequency of 14 MHz, and judicious length adjustments can sometimes include one other frequency band. All other frequencies require a transmatch. [citation needed] There are many variants of the G5RV antenna. Two variations of the G5RV design, called ZS6BKW ...
The automatic kind will also lower when the ignition switch is turned off. Unlike most car antennas adjusted directly by hand, power antennas retract completely beneath the surface that they are mounted on. This convenience could be found on most luxury cars by the late-1950s. The automatic power antenna became much more common in the 1970s. [1]
More common is electrical beam tilt, where the phasing between antenna elements is tweaked to make the signal go down (usually) in all directions. [1] This is extremely useful when the antenna is at a very high point, and the edge of the signal is likely to miss the target (broadcast audience, cellphone users, etc.) entirely.
Pyramidal horn antennas for a variety of frequencies. They have flanges at the top to attach to standard waveguides. A horn antenna is used to transmit radio waves from a waveguide (a metal pipe used to carry radio waves) out into space, or collect radio waves into a waveguide for reception.
Due to their omnidirectional radiation pattern, vertical monopole antennas are commonly used in terrestrial radio communication systems in which the direction to the transmitter or receiver is unknown or constantly changing, [7] such as broadcasting, mobile two-way radios, and wireless devices like cellphones and Wi-Fi networks, [8] [4] because they radiate equal radio power in all horizontal ...
Slotted array UHF television broadcasting antenna. As shown by H. G. Booker in 1946, from Babinet's principle in optics a slot in a metal plate or waveguide has the same radiation pattern as a driven rod antenna whose rod is the same shape as the slot, with the exception that the electric field and magnetic field directions are interchanged; the antenna is a magnetic dipole instead of an ...
