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.

Pointing losses can be calculated by determining the gain reduction due to misalignment between the transmitting and receiving antennas. This is typically done using the formula: ( L_p = 10 \log_{10} \left( \frac{A_r}{A_t} \right) ), where ( A_r ) is the effective area of the receiving antenna and ( A_t ) is the effective area of the transmitting antenna. Additionally, the angular misalignment in degrees can be converted to a loss in dB using the antenna's gain pattern. By assessing the angle of misalignment and the corresponding gain figures, you can quantify the overall pointing losses.
The relationship between antenna length and frequency is that shorter antennas are more effective at receiving and transmitting higher frequency signals, while longer antennas are better for lower frequency signals. This is because the length of the antenna needs to be proportional to the wavelength of the signal for optimal reception and transmission.

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.
Car radios are for receiving music and entertainment programs. Most aircraft will not have this type of radio. They will only have a 2 way transmitting and receiving radio for communicating with airports and other aircraft.

According to Faraday's law: "When current is passed through a conductor, an EM field is produced surrounding it." As an antenna contains one or more conductors, the terminals of which are connected to some voltage, when this voltage at the terminals is applied, it produces/induces the alternating current which radiates the elements in the electromagnetic field. (Transmission) The reverse of this occurs in reception; where the electromagnetic field from another source induces an alternating current in the antenna, and a corresponding voltage at the antenna's terminals.
