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 ...

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 ...

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.

For the first time, physicists have successfully converted electrical signals into photons and radiated them in specific directions using a low-footprint optical antenna that is only 800 nanometers in ...

Sinclair’s Heavy-Duty SY306R radome enclosed Yagi Directional Antenna offers10 dBd gain and 25 dB frontback ratio features a heavy-duty fiberglass radome which offers unbeatable protection for the ...

LoRa gear can be great for doing radio communications in a light-weight and low-power way. However, it can also work over great distances if you have the right hardware—and the right antennas in ...
