  2. Corner reflector antenna - Wikipedia

    en.wikipedia.org/wiki/Corner_reflector_antenna

    Corner reflector UHF TV antenna from 1954 with bowtie dipole driven element. A corner reflector antenna is a type of directional antenna used at VHF and UHF frequencies. [1] [2] It was invented by John D. Kraus in 1938. [3] [4] It consists of a dipole driven element mounted in front of two flat rectangular reflecting screens joined at an angle ...

  3. 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 ...

  4. Directional antenna - Wikipedia

    en.wikipedia.org/wiki/Directional_antenna

    Patch antenna gain pattern. A directional antenna or beam antenna is an antenna which radiates or receives greater radio wave power in specific directions. Directional antennas can radiate radio waves in beams, when greater concentration of radiation in a certain direction is desired, or in receiving antennas receive radio waves from one specific direction only.

  5. Direction finding - Wikipedia

    en.wikipedia.org/wiki/Direction_finding

    The Adcock antenna array uses a pair of monopole or dipole antennas that takes the vector difference of the received signal at each antenna so that there is only one output from each pair of antennas. Two of these pairs are co-located but perpendicularly oriented to produce what can be referred to as the N–S (North-South) and E–W (East-West ...

  6. Television antenna - Wikipedia

    en.wikipedia.org/wiki/Television_antenna

    The most common types of indoor antennas are the dipole [2] ("rabbit ears"), which work best for VHF channels, and loop antennas, which work best for UHF. [3] Outdoor antennas on the other hand are designed to be mounted on a mast on top of the owner's house, [4] or in a loft or attic where the dry conditions and increased elevation are ...

  7. Short backfire antenna - Wikipedia

    en.wikipedia.org/wiki/Short_backfire_antenna

    A short backfire antenna (or short back-fire, SBA, SBF or SBFA) is a type of a directional antenna, characterized by high gain, relatively small size, and narrow band. It has a shape of a disc with a straight edge, with a vertical pillar with a dipole acting as the driven element in roughly the middle and a conductive disc at the top acting as ...

  8. Ultra high frequency - Wikipedia

    en.wikipedia.org/wiki/Ultra_high_frequency

    The IEEE defines the UHF radar band as frequencies between 300 MHz and 1 GHz. [3] Two other IEEE radar bands overlap the ITU UHF band: the L band between 1 and 2 GHz and the S band between 2 and 4 GHz. UHF television antenna on a residence. This type of antenna, called a Yagi–Uda antenna, is widely used at UHF frequencies.

  9. AN/URC-117 Ground Wave Emergency Network - Wikipedia

    en.wikipedia.org/wiki/AN/URC-117_Ground_Wave...

    The main GWEN antenna operated intermittently in the LF band at 150 to 175 kilohertz (kHz) (below the bottom of the AM broadcast band at 530 kHz). The peak broadcasting power was from 2,000 to 3,000 watts. The UHF antenna operated at 20 watts, between 225 and 400 megahertz (MHz). [1]
