2. Moxon antenna - Wikipedia

   en.wikipedia.org/wiki/Moxon_antenna

   Moxon antenna for the 20-meter band.The antenna is the faint rectangle of wires held in tension by the bent X-shaped support frame. Moxon antenna for the 2-meter band. The Moxon antenna or Moxon rectangle is a simple and mechanically rugged two-element parasitic array, single-frequency antenna. [1]

   First-generation Chevrolet Silverado 2500HD (2001–02 Regular Cab) The GMT800 Silverado/Sierra 1500 and 2500 pickup trucks were released in August 1998 as 1999 models. The "classic" light-duty GMT400 C/K trucks continued to be produced for the first two years alongside the new models, and the Heavy-Duty GMT400 pickups (alongside the GMT400 SUVs) were continued until 2000, with the new GMT800 ...

   Used for elevated base station antennas for land mobile radio systems such as police, ambulance, and taxi dispatchers. Mast radiator A radio tower in which the tower structure itself serves as the antenna. Common form of transmitting antenna for AM radio stations and other MF and LF transmitters.

5. Monopole antenna - Wikipedia

   en.wikipedia.org/wiki/Monopole_antenna

   A common type of monopole antenna at these frequencies for mounting on masts or structures consists of a quarter-wave whip antenna with a ground plane consisting of 3 or 4 wires or rods a quarter-wave long radiating horizontally or diagonally from its base connected to the ground side of the feedline; this is called a ground-plane antenna.

6. Whip antenna - Wikipedia

   en.wikipedia.org/wiki/Whip_antenna

   The whip antenna is a monopole antenna, and like a vertical dipole has an omnidirectional radiation pattern, radiating equal radio power in all azimuthal directions (perpendicular to the antenna's axis), with the radiated power falling off with elevation angle to zero on the antenna's axis. [1]

7. Antenna (radio) - Wikipedia

   en.wikipedia.org/wiki/Antenna_(radio)

   For instance, if a radio wave passing a given location has a flux of 1 pW / m 2 (10 −12 Watts per square meter) and an antenna has an effective area of 12 m 2, then the antenna would deliver 12 pW of RF power to the receiver (30 microvolts RMS at 75 ohms). Since the receiving antenna is not equally sensitive to signals received from all ...
