Good quality Long Range RF Module for sales
Good quality Long Range RF Module for sales
We are very satisfied with their service and products, I bought their long range audio modules, at the begining I could not installed the modules, they taught me step by step and finally I got it! The modules work well and help me won the bid! Best Regards! Santithamkul

—— Santithamkul from Thailand

I visited many factories before I placed order for my radio modem. The reason I choose them is their professional skill and their excellent service. They do very best in every details. I like this factory and also like their lovely sales people! I will recommend more business partners to do business with them.

—— Makarov From Russia

Very excellent products and excellent service! I visisted many factories in China but none of them were meet my request! I finally chose them because many of my partners recommanded this company to me! The I/O Modules they sold were brilliant! It makes us more convenient with wireless solution!

KYL-668H BNC 25W High Power 20KM Wireless Voice And Data Transceiver UHF/VHF Wireless Transmitter

 

•Features


1. Transmission power

Using imported power amplifier module inside , transmission power 25W (adjustable ), Dimension 108mm × 128mm × 28mm.

2. ISM band working frequency, no need to apply carrier frequency, such as 150/230/450MHz etc, up to 256 channels.

3. High anti-interference ability and low bit error rate

Based on the MSK modulation method, an efficient communication protocol is used. When the channel error rate is 10-2, the actual bit error rate can be 10-5 ~ 10-6.

4. Multi-Baud rate.

Air Baud rate: 1200bps, 2400bps , Interface baud rate 1200,2400,4800,9600,19200, can be set by users

5. Can use the computer to set the transmission frequency, change the channel, and determine the working mode.

6. Can be as Receiver or transmitter, half-duplex communication, switching quickly.

7. Double phase-locked loop, dual VCO structure, high stability.

8. RS-232, RS-485, TTL Multiple standard interfaces are optional and can be directly connected to user equipment.

9 . The interface uses standard TTL, RS-232 (or RS-485) levels and can be directly connected to a microcontroller or personal computer

Attentions

1. Power Supply:

Due to the big power of radio station, the general transmission power is 25W, the power supply capacity meets 12V 8A. Please select a power supply with a better ripple factor and strong anti-interference ability. If The switching power supply is used. Please pay attention to keeping the antenna away from the power supply as much as possible because the antenna may affect the normal operation of the switching power supply. When radio station transmission fails, check if the power supply voltage is tampered by the antenna, it is one of the troubleshooting methods.


2. Antenna:

The antenna should be selected according to the frequency band used by the radio station. In long-distance transmission, directional antennas or high-gain antennas should be used, which should be set as high as possible.The impedance of antennas and its cable should match the one of interface of the module (50 Omega;). If the antenna impedance does not match, the module efficiency will be very low, the power consumption will increase, and it will be easily damaged for radio station. Antenna erection should be paid attention to lightning protection and antenna directionality, and grounding should be good.


3. Cable

The feeder line is a coaxial cable, which connects between the radio and the antenna. Selecting feeder line should pay attention to the following indicators:

Impedance: 50 Omega; (There are two types of 75 Omega; and 50 Omega, please note the difference)

Attenuation: Attenuation Decibels (DB) per meter feeder line. The smaller, the better.

Wire diameter: The thicker the feeder line diameter and the thicker the shield, the smaller the attenuation of the feeder.

Feeder line connector: The two ends of the feeder line must match the ones of the antenna and radio station. The connector's impedance is also 50 Omega; and it must be securely connected. When installing the feeder line,be careful not too tightly. Take a loop around the feeder line when enter the room,which prevents rainwater from entering the radio station. In Dorayan areas or when the antenna is installed at a high level, an arrester must be installed.


4. Cooling

When the radio station is transmitting for a long time, heat generated must be emitted in a timely manner. If can not, it may easily cause the wireless transmission to work abnormally.
