  2. Rubber ducky antenna - Wikipedia

    en.wikipedia.org/wiki/Rubber_ducky_antenna

    The rubber ducky antenna (or rubber duck aerial) is an electrically short monopole antenna, invented by Richard B. Johnson, that functions somewhat like a base-loaded whip antenna. It consists of a springy wire in the shape of a narrow helix , sealed in a rubber or plastic jacket to protect the antenna. [ 1 ]

  3. List of United States television stations available in Canada

    en.wikipedia.org/wiki/List_of_United_States...

    Low-power HDTV signal only available with full-size rooftop antenna, but a standard-definition WWNY-DT2 digital subchannel provides solid A-grade coverage over-the-air in Kingston, Ontario. More-distant Syracuse and (later) Buffalo signals are distributed by Kingston's Cogeco cable system instead of the more local Watertown affiliate.

  4. Coverage (telecommunication) - Wikipedia

    en.wikipedia.org/wiki/Coverage_(telecommunication)

    Coverage depends on several factors, such as orography (i.e. mountains) and buildings, technology, radio frequency and perhaps most importantly for two-way telecommunications the sensitivity and transmit efficiency of the consumer equipment. Some frequencies provide better regional coverage, while other frequencies penetrate better through ...

  5. Whip antenna - Wikipedia

    en.wikipedia.org/wiki/Whip_antenna

    Whip antenna on portable FM radio receiver Whip antenna on car. 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 ...

  6. Antenna types - Wikipedia

    en.wikipedia.org/wiki/Antenna_types

    The category of simple antennas consists of dipoles, monopoles, and loop antennas. Nearly all can be made with a single segment of wire (ignoring the break made in the wire for the feedline connection). [citation needed] Dipoles and monopoles called linear antennas (or straight wire antennas) since their radiating parts lie along a single ...

  8. Effective radiated power - Wikipedia

    en.wikipedia.org/wiki/Effective_radiated_power

    The latter factor is quantified by the antenna gain, which is the ratio of the signal strength radiated by an antenna in its direction of maximum radiation to that radiated by a standard antenna. For example, a 1,000 watt transmitter feeding an antenna with a gain of 4× (equiv. 6 dBi) will have the same signal strength in the direction of its ...

  9. Discone antenna - Wikipedia

    en.wikipedia.org/wiki/Discone_antenna

    The discone antenna has a useful frequency range of at least 10 to 1. [2] [3] When employed as a transmitting antenna, a properly constructed discone is just as efficient as an antenna designed for a more limited frequency range. The extra bandwidth comes from the controlled taper and large termination radius of the cone.
