How to debug the Antenna after installed?

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.  ...

What do you need to know when installing an outdoor antenna

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?  ...

The History of M, N, SMA and BNC Antenna Connector

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.  ...

What's the Spring antenna

The spring antenna is also called the helical inductive antenna, which is a kind of helical antenna. It can radiate and receive radio waves. when transmitting, it can convert high-frequency current into electromagnetic waves; when receiving, it can convert electromagnetic waves into the high-frequency current. So it plays a very important role in radio communication.  ...
