He put it to work listening to a NOAA weather satellite on 137 MHz by configuring it in a horizontal V-dipole arrangement. The antenna legs are spread about 120° apart and adjusted to about 20.5 ...

Folded Dipole Antenna. November 17, 2009 by P. Marian ... Using a 3 – 12 V lightbulb we can make a symmetrical antenna. Hold the lightbulb and touch the folded dipole, move from end point to middle.

The dipole antenna is a half-wavelength structure made of wire, tubing, printed-circuit board (PCB) copper, or some other conductive material. It is divided into two equal quarter wavelengths and ...

For this specific antenna, [W3CT] is putting together an inverted-V which is a type of dipole antenna. Rather than each of the dipole’s legs being straight, the center is suspended at some point ...

Antennas installed at 18 U.S. high schools detected bursts of radio activity that can precede solar disturbances capable of ...

Dipole Antennas. White Paper WHP 132. Download. Published: 1 January 2006. Abstract. Much of the work of Spectrum Planning Group is based on well-established principles of 'antennas and propagation'.

Mobile radios, such as for vehicles, use trunk- or roof-mounted monopole or dipole antennas. You also see monopole antennas on portable phones, pocket radios and walkie-talkies.

Meaning "two poles," a dipole antenna is the simplest type of antenna, consisting of an electrically conducting wire or rod one half the length of the maximum desired wavelength. The wire or rod ...
