Whip-a-way
{{Unreferenced, date=May 2019, bot=noref (GreenC bot) The Whip-a-way was a type of folding whip antenna. It was popular with users of Citizens band radio, and also had military uses. Versions Consumer The Whip-a-way is a seven-section, tubular, folding whip antenna. A plastic-covered cable (or braided plastic cord) under spring tension is threaded through the sections to keep them together when assembled for operation and prevent their separation or loss when disassembled. Spring tension is provided by a spiral spring in the base section. An antenna top cap installed on the tip of the antenna provides protection for personnel. The construction is the same as is used for sectional fishing poles. The base has a male 3/8-24 thread which is the same as is used on most ham radio and CB antennas. The antenna was 9 feet long when fully assembled. The product was distributed by South Shore Distributing of Hempstead, New York The Town of Hempstead is the largest of the three towns in N ...

Whip Antenna
A whip antenna is an antenna consisting of a straight flexible wire or rod. The bottom end of the whip is connected to the radio receiver or transmitter. A whip antenna is a form of monopole antenna. The antenna is designed to be flexible so that it does not break easily, and the name is derived from the whip-like motion that it exhibits when disturbed. Whip antennas for portable radios are often made of a series of interlocking telescoping metal tubes, so they can be retracted when not in use. Longer whips, made for mounting on vehicles and structures, are made of a flexible fiberglass rod around a wire core and can be up to long. The length of a whip antenna is determined by the wavelength of the radio waves it is used with. Their length varies from compact electrically short antennas wavelength long, up to wavelength to improve directivity. The most common type is the ''quarter-wave whip'', which is approximately long. Whips are the most common type o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citizens Band Radio
Citizens band radio (CB radio) is a land mobile radio system, a system allowing short-distance one-to-many bidirectional voice communication among individuals, using two-way radios operating near 27 MHz (or the 11-m wavelength) in the high frequency or shortwave band. Citizens band is distinct from other personal radio service allocations such as FRS, GMRS, MURS, UHF CB and the Amateur Radio Service ( "ham" radio). In many countries, CB operation does not require a license and may be used for business or personal communications. Like many other land mobile radio services, multiple radios in a local area share a single frequency channel, but only one can transmit at a time. The radio is normally in receive mode to receive transmissions of other radios on the channel; when users want to communicate they press a "push to talk" button on their radio, which turns on their transmitter. Users on a channel must take turns transmitting. In the US and Canada, and in the EU and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amateur Radio
Amateur radio, also known as ham radio, is the use of the radio frequency radio spectrum, spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency, emergency communications. The term ''"radio amateur"'' is used to specify ''"a duly authorized person interested in radioelectric practice with a purely personal aim and without wikt:pecuniary, pecuniary interest"'' (either direct monetary or other similar reward); and to differentiate it from commercial broadcasting, public safety (police and fire), or two-way radio professional services (maritime, aviation, taxis, etc.). The amateur radio service (''amateur service'' and ''amateur-satellite service'') is established by the International Telecommunication Union (ITU) through their recommended radio regulations. National governments regulate technical and operational characteristics of transmissions and issue individual station li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hempstead (village), New York
Hempstead is a village (New York), village located in the Hempstead, New York, Town of Hempstead in Nassau County, New York, Nassau County, on Long Island, in New York (state), New York, United States. The population was 59,169 at the 2020 United States census, 2020 census, making it the most populous village in New York. The Incorporated Village of Hempstead is the site of the seventeenth-century "town spot" from which English and Dutch settlers developed the Town of Hempstead, the North Hempstead, New York, Town of North Hempstead, and ultimately Nassau County. It is the largest community by population in both the Town of Hempstead and Nassau County. Hofstra University is partially located in Hempstead. Etymology Hempstead may have been named after Hemel Hempstead in the England, English county of Hertfordshire, where village founder John Carman was born. Another theory regarding the origin of the village's name is that it is derived from the town of Heemstede in the Nether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antennas
In radio-frequency engineering, an antenna (American English) or aerial (British English) is an electronic device that converts an alternating electric current into radio waves (transmitting), or radio waves into an electric current (receiving). It is the interface between radio waves propagating through space and electric currents moving in metal conductors, used with a transmitter or receiver. In transmission, a radio transmitter supplies an electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves (radio waves). In reception, an antenna intercepts some of the power of a radio wave in order to produce an electric current at its terminals, that is applied to a receiver to be amplified. Antennas are essential components of all radio equipment. An antenna is an array of conductor segments ( elements), electrically connected to the receiver or transmitter. Antennas can be designed to transmit and receive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
