We often hear from our customers that the signal of their walkie-talkie is not good, and sometimes it is intermittent. Is there any high-power walkie-talkie that can solve the problem of the walkie-talkie call? Generally speaking, the higher the power, the farther the transmission, the better the penetration effect. However, walkie-talkies are generally held close to the human head. So for the basement or a relatively large building, the signal of the walkie-talkie is not good, what solution is there? Today, the editor based on the bad signal of the basement walkie-talkie, what should I do if I can’t receive the walkie-talkie signal? To help you solve this kind of problem:
A : The basement signal is bad Generally, the reinforced concrete walls in the basement of residential properties are relatively thick, and the signal of the walkie-talkie is attenuated greatly. It is difficult to communicate with the upstairs in the basic basement. For such customers, if there is a repeater device, the frequency resource will not be increased. , Expand the coverage of the original base station; through the signal test equipment, clarify which areas of the basement have signal blind areas, and increase the antenna layout in the blind areas; If there is no repeater equipment, add repeater equipment. Take DMR digital repeater as an example. A digital repeater can use two channels. This needs to be configured according to the customer’s own channel usage. Repeater equipment. The entire basement is covered by coaxial cables and antennas; an outdoor antenna is added on the roof to ensure a good signal in a certain area upstairs.
B: The signal of the intercom inside the building is not good For clubs, KTVs and other places with relatively large floor areas, because of the large area and the decoration of the walls, the signal of the walkie-talkie is poor. For the number of channels used, a wall-mounted annd mobile repeater CD-920 can be arranged. This repeater The built-in power duplexer only needs to be hung on the wall and can be used after connecting the antenna.
C: The signal of the walkie-talkie in a zero-time place is not good For example, some emergency incident handling, high-end conference activities, and the signal of the walkie-talkie are not good. What should we do? We recommend using a built-in compact design with a thickness of only 41mm and a weight of less than 3kg. Built-in duplexer: optional built-in mini duplexer, the internal space is more compact, and the volume is smaller. For outdoor construction sites, field activities, etc. From a practical point of view, enthusiasts do not always need dual-channel reception at the same time. In many cases, they only need to wait for one channel. The other channel is cumbersome to receive. Therefore, it is more to choose between dual-channel reception or single-channel reception. The dual-frequency dual-receiving radio, most of the imported high-end mobile stations on the market have such a humanized design.
