Description:
In order to realize the long-distance communication, we need repeater. But the price of normal manufacturer of repeater is very high, so this new type repeater is just launched! The talk range is about 5 ~ 8Km in open area, or 1 ~ 2Kmin the city with tall buildings.
Features:
- With this two way radio repeater box, both of the radios can transmit and receive.
- The operation is very simple, and nopower supply needed!
- You do not need to change any part of the radio.
- All you need is just two handheld radios and connect the cables to the external mic/spk port (2.5mm&3.5mm).
- Applicable to relay station and the relay station between the link, signal extension, field construction cable erection, underground mine, cave construction, culvert emergency rescue, V-U transit.
Specifications:
Color: Black
Host size: Approx. 6 * 4.5 * 2.3cm / 2.4 * 1.8 * 0.9in
Total length: Approx. 170cm (82cm + 6cm + 82cm) / 5.6ft
Material: ABS
Distance: 5 ~ 8Km in open area, 1 ~ 2Km in a cluster of buildings
Connector: 2.5mm, 3.5mm
Package weight: 84g
Working Mode:
Different frequency uplink and downlink forwarding: A machine as a signal uplink receiver, B machine as a signal downlink transmitter. Has reached the purpose of relay.
Two-way forwarding: A machine receives while B machine is transmitting. B machine receives while A machine is transmitting. To achieve two-way forwarding function.
Adopting audio trigger mode, so the volume of intercom receiver should be adjusted to the maximum when in use.
Package Included:
1 x Repeater Box (Only a Repeater Box, not including walkie-talkies)
Note:
- For one-way relay box forwarding mode (conventional repeater mode)! A machine receives the signal, B machine sends the signal. The receiver / transmitter must be set to two different frequencies. The frequency of the conventional transmitter is higher than the receiver frequency. Usually, the high / low frequency difference is 10 M. The higher the frequency difference, the better.
- For one-way relay box, please do not inversely connect the jack, otherwise the relay box will not work.
- For two-way relay box, regardless of plug input / output; two-way relay box forwarding mode: A machine receives when B is transmitter, B machine receives when A is transmitter.
- Adopting audio trigger mode, so the volume of intercom receiver should be adjusted to the maximum when in use, or there may be non-forwarding state.
- If the transmitting delay time is too long (more than 3 seconds), because of the radio transmitter antenna too close to the relay box, you can solve the interference problem by an external radio antenna.
