Car roof-mounted 6 meter halo antenna for mobile amateur radio (by WA8FJW). Note the triple-loop. Note the triple-loop. The halo is a larger antenna, and consequently is more efficient than a small loop, and roughly the same efficiency as a dipole antenna cut for the same frequency.
A monopole antenna is a class of radio antenna consisting of a straight rod-shaped conductor, often mounted perpendicularly over some type of conductive surface, called a ground plane. [ 1 ] [ 2 ] [ 3 ] The driving signal from the transmitter is applied, or for receiving antennas the output signal to the receiver is taken, between the lower end ...
the upper half of a vertical full-wavelength loop antenna mounted on the ground (not to be confused with the visually similar but electrically different half-square antenna described below, under array antennas, [r] nor to be confused with the halo antenna, described next). The full loop is cut at two opposite points along its perimeter, and ...
Car-roof-mounted 6-meter halo antenna for mobile amateur radio (WA8FJW). Notice the triple-loop. Notice the triple-loop. On the VHF bands and above, the physical diameter of a halo is small enough to be effectively used as a mobile antenna.
Whip antenna on portable FM radio receiver Whip antenna on car. A whip antenna is an antenna consisting of a straight flexible wire or rod. The bottom end of the whip is connected to the radio receiver or transmitter. A whip antenna is a form of monopole antenna. The antenna is designed to be flexible so that it does not break easily, and the ...
Types of antenna often mounted on mast radiators are: fiberglass whip antennas for land mobile radio systems for taxi and delivery services, dish antennas for microwave relay links carrying commercial telecommunications and internet data, FM radio broadcasting antennas consisting of collinear bays of twisted dipole elements, and cellular base ...
