A spire is an architectural feature on a building.
It is a tall, tapering peak on a roof.
An antenna is a functional piece of equipment for receiving or transmitting electromagnetic signals (e.g. radio, TV, cellular telephone).
Some types are tall but the shape depends almost entirely on the signal to be sent or received.
You cannot have a spire without a steeple, a steeple can be a tower not necessarily tapering to a point. A spire tapers to a point.
There is no difference between the two.
Hertz Antenna is lambda by 2 antenna & marconi antenna is lambda by 4 antenna...
An active antenna has a amplifier built in, a standard antenna does not. AKA powered antenna.
An omnidirectional antenna can be practically implemented but an isotropic antenna cannot be implemented practically. An isotropic antenna resembles an ideal antenna with ideal values for all parameters.
No. Currently the tallest building in NYC is the Empire State Building. But the Freedom Tower (now called World Trade Center 1), the replacement for the WTC, will be the tallest building in NYC.
It is about as tall as an 81 story building so, 1,063 to the antenna spire or 986 to the roof, (in feet).
about 40 db about 40 db
To the antenna/spire: 605 feet (184m) To the top floor only: 520 feet (160m)
Antenna spire : 328m Top floor : 222m
Frakfurt, Germany is the headquarters of Commerzbank. It is a 56 story skyscraper, which has an antenna spire, which gives the tower a total height of 980 feet.
If it has antenna that stick up it is a boy and if it has antenna that stick out it is a girl.
