Feature:

1. In order to carry out long‑distance communication, we need a repeater. The walkie‑talkie uses the repeater to increase the communication distance by more than 10 kilometers, and is capable of two‑way communication (reception and transmission).
2. The operation is very simple, no power supply is required, you do not need to replace any part of the walkie‑talkie, you only need two portable walkie‑talkies and connect the cable to the external mic/spk port (2.5mm and 3.5mm).
3. Made of high‑quality ABS material, durable, wear‑resistant, increase its service life, and the connection is also very convenient, only two two‑way handheld walkie‑talkies are connected to the repeater through the earphone jack, which is convenient to use.
4. Applicable to multiple scenarios: 1. The connection between the relay station and the relay station. 2. Signal extension relay station signal coverage area. 3. Construction of cable erection site 4. Underground mine. 5. Emergency rescue for cave construction. 6. Culvert. 7. V‑U section relay. 8. The signal connection between the small basement and the ground intercom. 9. Use emergency in large‑scale events and other occasions!
5. Operating mode: 1. Transponder downlink transmission (differential and conventional relay station), machine A is used as the uplink receiving signal, and machine B is used as the downlink transmission of the signal. Achieved the purpose of relay. 2. Two‑way forwarding, receiver one, transmitter b. b machine to receive, the first phase machine. Realize two‑way forwarding function. 3. The audio trigger mode relay box, when in use, the received walkie‑talkie signal is at full volume!

Specification:

Item Type: Walkie‑Talkie Two Way Relay Box
Material: ABS
Colour: Black
Connector: K Port is Used for Kenwood and Most Brand Walkie-talkies with the Same Connector
Antenna/duplexer installation application:
1. Original multiplexer: Two hands connected to a repeater station, such as a peerless multiplexer, each hand must use two antennas separately! Both antennas must be lifted vertically! And between the two, they tried to distance themselves. At least not less than 5m / 16.4ft. (Two walkie‑talkie antennas prevent parallel erection!)
2. Duplexer: Purchase the corresponding frequency/power duplexer, couple the output ends of the two unit antennas at the "contact point" to the duplexer at the transmitting end and the receiving end respectively, and set the player reservation table of the corresponding frequency (one frequency must It is consistent with the duplexer). In the case of a duplexer, the repeater only needs to connect to an antenna! And there is no special attention when setting up the antenna!
3. We recommend using a duplexer, because there are no special requirements for the antenna when the duplexer repeats the station! As long as the height is sufficient. 4. It is recommended to use "Original for Kenwood" or "for Motorola" brand walkie‑talkies.
Single/two‑way relay frequency box setting prompt:
1. One‑way relay box transmission mode (conventional relay station mode)! A machine receives signals and sends signals from the machine b. The transmitter/receiver should be set to two different frequencies, the frequency is higher than the regular receiving frequency of the transmitter, and the difference between high/low and high/low is 10m. The larger the frequency difference, the better.
2. The one‑way relay box should not be connected reversely when using the connector, otherwise the relay box will not work.
3. The two‑way plug of the relay box does not divide the input/output, and the transmission mode of the relay box is two directions: a machine receives b sends, and machine b sends and receives a.
