Coordinate systems, conventions and transformations are introduced and are used to illustrate the effects of alignment errors in antenna measurements. Vector isometric rotations are then used as the ...

The NSI-MI Technologies measurement system is ideal for measuring millimetre wave antennas packaged on chip from 10GHz to 110GHz. The NSI 2000 software allows for radiated results to be processed and ...

Many TV antennas claim to reach 100 miles or more, but range isn’t the key. Antenna gain is a better measure of performance. It shows how well an antenna captures UHF and VHF signals. Distance matters ...

If I ask you to picture a radio telescope, you probably imagine a large dish pointing to the sky, or even an array of dish ...

Measurements of Global Navigation Satellite Systems (GNSS) refer to the electrical phase centers of the GNSS transmitting and receiving antennas. The phase center offsets (PCOs) between the electrical ...

Getting the two together, as with this field-portable antenna made from a tape measure, is a double win in any ham’s book. For [Paul (OM0ET)], this build seems motivated mainly by the ...

The tape measure elements make the antenna easy to handle and foldable, not to mention pretty cheap to build. And what’s not to love about that?

Reaching indoor antennas requires more power, offsetting efficiency gains made by today’s solid-state technology ...

Here’s how it works. I couldn't live without a TV antenna. It's as important to me as any streaming service because it allows me to watch sports, sitcoms and news without having to pay a monthly ...

Quadsat has worked with ALL.SPACE to conduct a comprehensive evaluation of its electronically steerable antenna (ESA) for use on LEO constellations.

And so it is that the age of the disruptors has come for college football, too. There's Lane Kiffin, who has been thumbing ...

The best indoor TV antennas let you receive free over-the-air broadcast TV channels without having to install a large outdoor antenna on the roof of your home. You’ll find that the main ...
