I've constructed hundreds of antennae in the past. Bowtie dipole arrays, biquads, parabolic reflector dipoles, straight up yagi, logarithmic yagi, log periodic, heliacal and simple 1/4 whips. So when ...

This article describes the phases for the construction of a Yagi antenna. The calculations of the parameters are made using 4NEC2 software. This type of antenna is used for transmissions and ...

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 ...

A paper published in Nature this week details how researchers have taken a common antenna design and replicated it on the the nanoscale level. When a regular TV aerial that handles radio frequencies ...

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 ...

When we take a new Wi-Fi router from its box, the stock antenna is a short plastic stub with a reverse SMA plug on one end. More recent and more fancy routers have more than one such antenna for ...

Directing the fluorescence from nanoscale emitters such as single molecules and single quantum dots is a key factor in a wide range of applications, from the efficient detection of molecules for ...

One of the first things that an amateur radio operator is likely to do once receiving their license is grab a dual-band handheld and try to make contacts with a local repeater. After the initial ...

The 290 Series VHF Yagi Antenna are available in 2, 3, and 6 element configurations. All our antennas can be completely customized to your applications. Our antennas can be black anodized, welded, ...

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.

LOGAN, Utah — Oxford Space Systems announced the successful deployment Aug. 7 of its Yagi very high frequency, high gain antenna. The U.K. company released images showing Yagi deploy on the Ymir-1 ...
