Common Types of Short-wave Antennas

 May 10,2019   aliunce   0 Comments   Radio knowledge

The commonly used short-wave antennas are mainly classified into three categories, the vertical antenna (GP), the dipole antenna (DP), and the Yagi antenna (YAGI). In addition, there are frame type, diamond type, dish type, etc. Here we mainly discuss the first three types of antennas, among which the focus is on dipole antenna and its deformation.  ...

Radio Antenna Erection and Standing Wave Ratio

 Mar 19,2019   aliunce   0 Comments   Radio knowledge

We know the VSWR of the antenna system is close to 1:1. If it is close to 1:1, it is good. I often hear this question: But what if I can't reach 1? If the standing wave ratio is as small as a few, is the antenna qualified?  ...
