Antenna is a relatively common device, widely used in radio, television, radio communications, radar, navigation, electronic countermeasures, remote sensing, radio astronomy and other fields. Antenna is a device that can effectively radiate electromagnetic waves to a specific direction in space or can effectively receive electromagnetic waves from a specific direction in space. All the equipment t...
The same frequency is the premise that two walkie-talkie scan talk. If they are not on the same frequency, even walkie-talkies of the same brand and model cannot talk; if the frequency is the same, even walkie-talkies that are not of the same brand can talk. So it matters. Generally speaking, there are two types of handheld radios: a professional walkie-talkie, and an amateur walkie-talkie, which ...
The walkie-talkie should use the original battery. If the battery used by the walkie-talkie is not the original battery, it will have a negative effect on the walkie-talkie itself. The use of different types of batteries and different types of chargers will also affect the use of the walkie-talkie battery, especially the service life of the walkie-talkie battery.We provide all kinds of matching or...
There are many intercoms on the market that claim to be 10km intercoms, 50km intercoms, 100km, 500km or even 1000km intercoms, but when you actually use them you will find that the data may have to be cut in half.As we all know, high power walkie talkies can make the communication distance longer, which can reach 5-15 KM or even further in the suburbs. So,what is the reason for the shortening of t...
The analog radio is (also known as a traditional walkie-talkie) designed with analog communication technology, which modulates the stored signal to the walkie-talkie's transmission frequency. However，the advantage of the SIM card radio is that it breaks through the limitation of distance. There is no limit to the distance of the national intercom. As long as there is a network, the intercom can be...
People who have just started to get in touch with radio will definitely be puzzled: Why is there a brief rustling sound on the walkie-talkie after the other one finishes speaking? This starts with the noise of the walkie-talkie. When the walkie-talkie is transceiving, it will not only receive useful sound modulation signals, but also receive white noise in the air, as well as noise generated by th...
We know that the antenna of the intercom is proportional to the transmission and reception of the walkie-talkie, and the antenna is a device that emits electromagnetic waves into the air. We usually use walkie-talkies in order to send more power into the air, so that when the other party receives the signal, there is still enough power to restore the content of the information. The antenna is an i...
First of all,make it clear that we can carry walkie-talkies on a plane. However, when we go through airport security, we need to cooperate with the security officer by switching off the walkie-talkie and removing the battery from the radio and carrying it separately from the main unit. It is also important to note that the walkie-talkie cannot be switched on and used on the aircraft. The aviation ...
