The structure of two way radio
on May 9,2023.
Antenna There are many kinds of antennas, such as two way radio rubber antenna, hand-held radio pull rod antenna, vehicle mounted sucker antenna, FRP omnidirectional antenna, Yagi directional antenna, and suction top antenna. Now many two way radios are full frequency segment, 136-174M, 400-470M, although some small manufacturers known as the antenna is full segment, but it is best to distinguish the antenna high and low segment, for the full segment of the machine, frequency above 450M with 400 high antenna, frequency below 420M, Antenna with lower than 400 is much better, especially when the user on the call distance requirements, more attention should be paid to these. The effect of ordinary tie rod antenna is not big, the length of rubber antenna is a great deal of attention, not the longer the better, if the effect is significant, MOTOROLA and other international brands why not do it? The gap between the car suction cup antenna is very big, good to hundreds of pieces or even more than one thousand yuan, the most cheap one is just 40 yuan, it is recommended that we sell more than one hundred antenna, quality assurance, sensitivity is also higher, the distance of the sales of the platform also has a greater help, or that sentence, a good horse with a good saddle. Channel value Some two way radios have displays and some do not. Two way radios without displays generally have 16 channels such as Senhaix 1430, 15 regular channels and one scan channel. Two way radios with display screens generally have 99 or 128 channels such as SenhaiX 8800 and SenhaiX 8600. Moreover, two way radios store 99 or 128 channels, maritime two way radios are generally 128 channels. Status indicator The status indicator of the two way radio refers to the two status indicators of transmitting and receiving. Under normal circumstances, the indicator is out when the two way radio does not work, the indicator is red when transmitting, the indicator is green when receiving, and the signal is not good when the two way radio receives, the green indicator is not always on, but irregular "jitter". If the two way radio battery is low and it is in standby state, the red indicator blinks, indicating that the battery is low. You need to replace the battery. If you do not replace the battery in time, a beep will beep when you press the launch button of the two way radio. Horn Horns of two way radio have several calibers, the sound quality of the speaker and the size of the sound cavity has a large system, the sound quality of the big two way radio is better than the sound quality of the small one. Battery Batteries are an important part of a two way radio. A good battery for a two way radio is like a good saddle for a good horse. Walkie-talkie batteries can be divided into nickel cadmium battery, nickel metal hydride battery, lithium ion battery. Each of the above batteries is equipped with explosion-proof battery, ordinary battery can not be used in flammable and explosive gas ...
