Hence the nominal value of maximum for a monopole antenna is about 5.15dBi.
The vertical antenna, on the other hand, is a monopole antenna.
It consists of a monopole antenna running parallel to a ground plane and grounded at one end.
Electrically short monopole antennas have low resistance and high reactance.
Monopole antennas that use guy-wires for support are called masts in some countries.
The most common ground plane for large monopole antenna and some other kinds of radio antenna.
Antennae Both bands made use of a cylindrical monopole antenna mounted on a ground plane.
Monopole antennas have become one of the components of mobile and internet networks across the globe.
The inverted-L antenna is a monopole antenna bent over to run parallel to the ground plane.
The inverted-F antenna is an evolution of the basic quarter-wave monopole antenna.
A typical AM broadcast antenna is a series-fed monopole antenna above a ground system.
Monopole antennas consist of a single radiating element such as a metal rod, often mounted over a conducting surface, a ground plane.
This assumes that the monopole antenna is mounted above an infinite ground plane and that the antennas are lossless.
Examples of monopole antennas are:
The far field radiation pattern is similar to an electrically short Dipole antenna or Monopole antenna.
The condition for resonance in a monopole antenna is for the element to be an odd multiple of a quarter-wavelength, λ/4.
One usually constructs the folded-unipole from an existing monopole antenna by shorting out the base insulator, thus connecting the tower directly to the ground system.
J-pole antennas with electrical connection to their supports often fare no better, and often much worse, than the simpler Monopole antenna.
(See Monopole antenna).
With a monopole antenna the counterpoise functions as a ground plane, reflecting the radio waves radiated downward by the antenna.
The wire antennas used with crystal receivers are monopole antennas which develop their output voltage with respect to ground.
A variation of a monopole antenna, it consists of a vertical metal rod or mast mounted over a conductive surface called a ground plane.
Monopole versions for use at lower frequencies have been built by placing vertical reflecting screens behind a vertical monopole antenna.
Free standing whip antennas exhibit an omnidirectional radiation pattern in the azimuth plane which is typical of vertical monopole antennas.
The monopole antenna was invented in 1895 by radio pioneer Guglielmo Marconi during his historic first experiments in radio communication.
The control trailer was the center of a web of leads to the array of vertical spike antennas thirty meters out from it.
Not only did the jet interfere seriously, but also the antenna were completely retracted, even spike antenna, during the passage through the atmosphere.
Then I shifted back to spike antenna and went on calling Peewee while moving across the pasture and pretending that I was on Venus and had to stay in touch with base because it was unknown terrain and unbreathable atmosphere.
Ceremonies were held at the Russia's cosmonaut training center, Star City, outside of Moscow, to recall the events leading up to the Oct. 4, 1957, launch of the 184-pound metal ball with the spiked antennas that beeped as it circled the Earth for 22 days.
