A system for matching impedance of antennas includes a first switch for receiving signals that includes a first power amplifier, a first low noise amplifier coupled to the first power amplifier and a first antenna coupled to both the first power amplifier and the first low noise amplifier. The ...
Matching transformer in vertical antennasOften it is necessary to provide some form of impedance transformation within the antenna itself.Often vertical antennas need to be fed with 50Ω coaxial cable, but the impedance of a vertical is typically lower than this: often around 20&Omeag;...

NextPrevious You will need the following materials: 1 aluminum can, something to mount the can to (I used a piece of scrap wood), coax cable and, most importantly, an impedance-matching transformer from RadioShack. NextPrevious First, start by cutting the soda can in half the long way with...
Conceptually, think of an antenna as an impedance transformer that converts 50 Ohms transmissions on a transmission line to the 377 ohm free-space environment. In the example above, we have a dipole antenna. As we saw before, the dipole is just a folded transmission line. In the dipole ...
