2. Television antenna - Wikipedia

   en.wikipedia.org/wiki/Television_antenna

   A short antenna pole next to a house Multiple Yagi TV aerials. Antennas are commonly placed on rooftops and sometimes in attics. Placing an antenna indoors significantly attenuates the level of the available signal. [19] [20] Directional antennas must be pointed at the transmitter they are receiving; in most cases great accuracy is not needed ...

   VK3IL - Multiband end-fed 80-10m antenna - NEC2 model file of a "MyAntennas EFHW-8010" multi-band antenna. Other retail books (such as The ARRL Antenna Book, Marcel De Canck's Advanced Antenna Modeling, and others) also include antenna model files. Most free or retail NEC software packages include an 'example' folder containing antenna model files.

5. UHF television broadcasting - Wikipedia

   en.wikipedia.org/wiki/UHF_television_broadcasting

   TV antenna manufacturers often rated their top-of-the-line "deep-fringe" antenna models with phrases like "100 miles VHF/60 miles UHF" if the antenna included UHF reception at all. (In the practice of electrical engineering, the frequency range in which an antenna is to be used is an important factor in its design.)

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. Channel Master - Wikipedia

   en.wikipedia.org/wiki/Channel_Master

   Channel Master's original product was a prefabricated television aerial with hinged elements which would unfold and snap into place; this patented design greatly reduced installation time as existing antenna designs at the time had to be bolted together from multiple pieces by rooftop installers. [17]

9. Reflective array antenna - Wikipedia

   en.wikipedia.org/wiki/Reflective_array_antenna

   The main lobe of the antenna can be steered electronically within a limited angle by phase shifting the drive signals applied to the individual elements. Each antenna element is fed through a phase shifter which can be controlled digitally, delaying each signal by a successive amount. This causes the wavefronts created by the superposition of ...
