A flat antenna. A more recent phenomenon for indoor antennas are flat antennas, which are lightweight, thin, and usually square-shaped with the claim of having more omnidirectional reception. They are also marketed as being more in line with modern minimalistic home designs. [14] Flat antennas may have a stand or could be hung on a wall or a ...
The North Tower of the original World Trade Center also had a 110-metre (360 ft) telecommunications antenna atop its roof, constructed in 1978–1979, and began transmission in 1980. When the buildings collapsed, several local TV and radio stations were knocked off the air until backup transmitters could be put into service. [13]

[ 1 ] Flat roofs are an ancient form mostly used in arid climates and allow the roof space to be used as a living space or a living roof .
If a given area is covered by many distributed antenna elements rather than a single antenna, then the total radiated power is reduced by approximately a factor N 1–n/2 and the power per antenna is reduced by a factor N n/2 where a simple power-law path-loss model with path-loss exponent n is assumed.
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.)
