Both these devices should only be used when necessary. In many cases a good aerial installation with good quality cables can be enough to receive good reception. A signal amplifier should only ...

While we wouldn’t want to document a computer motherboard with ASCII schematics, it’s great for a quick-and-dirty circuit diagrams. Not exactly schematics, but [Duckman] has some Arduino ...

The microstrip patch antenna is one of the simplest radiating structures that can be built using printed circuits. Single patch antennas and patch antenna arrays are widely used in communication ...

One of the first things that you learn in radio communications and broadcasting is that antenna impedance must be matched to the transmission line impedance and that the transmission line impedance ...

Ideally, if you are going to transmit, you want a properly-tuned resonant antenna. But, sometimes, it isn’t practical. [Ham Radio Rookie] knew about random wire antennas but didn’t ...

It's not as simple as dropping an antenna by a window and plugging it in. And while Wi-Fi calling can be a good alternative, not all carriers and phones support it. Most signal boosters come in ...

We can see how circuits work, and represent them with some simple diagrams, using basic electrical components like these. You start with a cell, or combination of cells. These could be batteries ...

Because boosters use old-school antennas that literally grab a signal out of the air, you do need a signal somewhere nearby.

If after going through all of our troubleshooting steps, including talking to your carrier to go over your options, you're still struggling to keep a good signal -- try a booster. A signal booster ...
