A sheet, an antenna, the best interpretation of the antenna man dong dong  ...

After we complete , it needs to be debugged. The purpose of antenna debugging is to make the antenna system resonate at the transceiver frequency by trimming the length of the antenna element. Match the impedance of the antenna system with the transceiver impedance of the radio. Debugging generally uses standing wave meter, power meter or antenna analyzer.  ...

Why is your signal report of 50W radio not as good as the one just 5W radio? That's because in addition to the environmental loss, the power of the radio has a lot of loss in the antenna system. So many hams like to install them antenna outdoor to reduce antenna system loss. But what do you need to know when installing an outdoor antenna?  ...

An easy-to-use, no complicated adjustment, novice antenna. If you don’t have a roof to set up a Ⅴ antenna and inverted V antenna. But you have a balcony, come on to try this 10 band shortwave balcony antenna.  ...

Referring to the representative symbols of amateur radios, it is estimated that a large number of hams will vote for the antenna (exactly, the Yagi antenna). The rest of hams may choose radio equipments. there will be few people notice the small thing of the antenna connector. If someone ask you, why is your device using the M head connector, how it is performing, and so on. Can you reply well? Today let's learn the antenna connector together.  ...

Both the antenna analyzer and the standing wave meter can be used to test the standing wave of the antenna feeder system, but the functions and characteristics of them are also quite different. So, should we choose an antenna analyzer or a standing wave meter?  ...

what are electromagnetic waves? how does the antenna send these electromagnetic waves out? how does the antenna realize the directional emission of electromagnetic waves? how do you measure the coverage and gain of the antenna's main lobe? After reading the article, you will understand.  ...

antenna SWR, antenna gain, and Directionality are reference factors for judging the quality of an antenna.  ...

Dipole antenna is the earliest, most widely, and the most commonly used simplest antenna in SW. But do you know which is dipole antenna in our commonly used antennas? How to work?  ...

Do you know the Yagi antenna? The yagi antenna works very well in direction finding and long-distance communication. Today we'll learn the Yagi antenna with Ailunce AY01.  ...
