When you think of directional ham radio antennas, you probably think of a Yagi, cubical quad, or a log-periodic antenna. These antennas usually are in a horizontal configuration up on a high tower.

Electrical engineer Ramachandra Bhat Koodur, who has built one of India’s best ham radio stations in Kavoor, recently installed a high-performing Yagi antenna, a directional antenna with a rotator, on ...

Active Elements: 32 Element Diameter: 5/16-inch Beamwidth, 16• +/- 1dB Gain: 12-14 dBi Maximum Height: 14 inches Maximum Width: 5 inches Maximum Length: 51 inches Polarization: Vertical or horizontal ...

Yagi antenna can be used at transmission or reception but are more used for transmitters. This antenna is a directional system consisting of an array of a dipole and a reflector and one or more ...

New Yagi Antennas come in 3dBi, 6dBi, 9dBi, 12dBi, and 14dBi gains. Each antenna gain family includes a variety of connector types installed including, N male, N female, SMA male and RP-SMA male.

The demonstration of a Yagi–Uda nano-antenna that operates at visible wavelengths gives hope for a convenient means of directing radiation patterns from nanoscale light sources such as single ...
