By What is meant by broadband antenna?
an antenna whose main parameters and characteristics do not vary substantially over a rather wide frequency band. Broadband antennas are used to transmit, receive, or transmit and receive radio signals with a wide frequency spectrum, for example, in television, radar, or radio astronomy.
How long is a shortwave antenna?
Shortwave broadcasters use frequencies that are from about 50 to about 400 feet long, and an effective antenna needs to be at least one-fourth of that length — and one-half is much better.
What is a biconical antenna used for?
Biconical antennas are used for emissions and immunity testing to meet various EMC standards specified by FCC, CISPR and EN. The broadband characteristics of the biconical antenna make it a good choice for making sweep measurements and for automated measurement systems.
What is broadband dipole antenna?
The broadband dipole antenna provides excellent performance for short to medium range circuits. The antenna comprises two horizontal conical sections, the elements of which are connected in the centre to a common feed line. The antenna is mounted between two guyed support masts.
What is the aperture of an antenna?
The aperture of the antenna is the area whose orientation is normal to the direction from where the electromagnetic wave is coming. This is done in order to intercept the equivalent power from the incoming wave as it can be produced by the antenna which is receiving it.
What is the best antenna to use for all shortwave frequencies?

Is there anything on shortwave anymore?
“There has been a massive decline in shortwave listenership, especially in Europe and North America,” said Andy Sennitt. “Shortwave is still significant in much of Africa, South Asia and parts of Latin America.”
What is a bowtie antenna?
A bowtie antenna uses triangular elements instead of straight rods as the antenna elements. A bowtie antenna is sometimes called a butterfly antenna because it looks like a butterfly with its wings held open. When the bow tie elements have a metal bar that closes the antenna, it may be called a cat’s whisker antenna.
What are the different types of wire antennas?
They can be found in vehicles (automobiles), ships, aircrafts, buildings etc. Wire Antennas come in different shapes and sizes like straight wire (Dipole), Loop and Helix. Perhaps the simplest of all antennas is the Short Dipole Antenna. It is a special case of the Dipole antenna.
How is a broadband antenna different from a wideband antenna?
It is distinguished from broadband antennas, where the passband is large, but the antenna gain and/or radiation pattern need not stay the same over the passband. The term Wideband Audio or (also termed HD Voice or Wideband Voice) denotes a telephony using a wideband codec, which uses a greater frequency range of…
Which is an example of a broadband antenna?
Broadband antennas are used to transmit, receive, or transmit and receive radio signals with a wide frequency spectrum, for example, in television, radar, or radio astronomy.
Is there an external antenna for 4G broadband?
External Antennas For 4G & 5G Broadband: Improve Signal Strength & Speed An external antenna can help to improve the speed and reliability of your 4G or 5G home broadband connection.
