Read in a study guide: 'Since the noise temperature of the antenna and the feeder could not be reduced below a limit, noise temperature of LNA is kept as low as possible.' I am trying to look for a ...
Consider a magnetic field (B-field) probe such as this one: (source) I understand that as as the magnetic flux through the loop formed by the coax shield changes, the charge carriers in the loop ...
I always assumed that the shape of the antennas was important; a vertical monopole for pitch and a horizontal loop for volume, thinking that this minimized their interference with each other. But it ...
I have a project for a small remote control in which I'll use a magnet instead of screws/etc. to close the case. Basically it is a two-piece plastic case in which one of the pieces has a magnet glued ...
