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 ...

4. Driven and parasitic elements - Wikipedia

   en.wikipedia.org/wiki/Driven_and_parasitic_elements

   Yagi antenna for UHF TV reception with 22 parasitic elements; 4 reflectors attached to the vertical bracket at left, and 18 directors attached to the horizontal beam at right. The driven element is attached to the black box next to the reflectors. The antenna is most sensitive to radio waves coming from the right, parallel to the antenna's axis.

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. Reflective array antenna - Wikipedia

   en.wikipedia.org/wiki/Reflective_array_antenna

   This reflective array television antenna consists of eight "bowtie" dipole driven elements mounted in front of a wire screen reflector. The X-shaped dipoles give it a wide bandwidth to cover both the VHF (174–216 MHz) and UHF (470–700 MHz) bands.

7. Guyed mast - Wikipedia

   en.wikipedia.org/wiki/Guyed_mast

   In such cases the antennas for directional radio services are mounted on the top of the free-standing part of the tower, while the guyed mast on its top carry the FM and TV antennas. They can be also used in order to upgrade small stable towers (like watertowers) with a long antenna mast for FM and TV broadcasting.
