Europe 863MHz-870MHz, US M902Mhz-928Mhz frequency bands.
Features:
1) This 868MHz signal amplifier module is a two-way amplified TDD working mode ,that is the transmit power and receiving sensitivity will be amplified equally.
2) The receiving/sending link has a high degree of isolation, and the receiving link can withstand strong external interference without causing self-excitation of the loop.
3) Compatible with various modulation methods such as LORA and FSK/ASK/OOK/MSK/GFSK.
Basic Parameter:
1. Receiving gain: 11dB±2dB
2. Receiving noise figure: at most 2.0dB
3. Transmission gain: 5dB – 11dB (±2dB) adjustable
4. Recognition threshold for receiving and sending switching: -2dBm
5. Input power range: 1dBm-25dBm
6. Operating Voltage:The power supply voltage can be between 3.6V-6.0V, maximum transmission power increases as the supply voltage increases.
7. Maximum transmit power:31.5dBm (1.4w) at 3.7V supply voltage; 33.5dBm (2.3w) at 5.0V supply voltage; 34.5dBm (2.8w) at 6.0V supply voltage
Work status indication:
- Receiving : green light is on, blue light is off
- Transmitting : blue light is on, green light is off
- In TDD working mode, the blue light and green light will flash alternately
Working current:
RX status: 10mA (±3mA)
TX status: at most 800mA (3.7v power supply); at most 1000mA(5.0v power supply); at most 1500mA (6.0v power supply)

Connector broke after 3 days. Noticed no difference in signal receive or transmit.

Caveat...I'm not an expert in radio waves or electronic components. I do have experience through tinkering and working with others as I'm sure many who are reading this do as well. With that said...I'm part of a large statewide "club" trying to get LoRa networks stretched as far as we can. I have a 30 foot tower with a 4 foot LoRa tuned antenna connected to a wisblock setup. Before the amp was installed I could not hear or be heard by nodes over 5 miles away. I received random chatter occasionally. After the amp was installed I had much more consistent tests with my group up to 25 miles. I will take that as a success. I still have terrain issues and usual hurdles because amps don't solve that.I use a POE power module with my wisblock and it has a pinned output option which powers this device.

For the price, its not bad, but don't expect magic. It would probably do a reasonable job of offsetting the loss in a medium length of coaxial cable but nothing spectacular. I did a number of tests to try and quantify its results, as well as looking at the spectrum on an analyzer.Do be aware if your signal is not filtered properly this seems to amplify 530-555MHz as well as 885-925MHz, so make sure your input signal is clean and free of spurious emissions.Here's my test results for gain in dB comparing the "raw" signals to amplified signals:NanoVNA TX sweep (flat curve, very nice)+9dBSpectrum analyzer monitoring Mesthtastic TX 906.680MHz (maintains same power curve across frequency domain)+6dBReal world Meshtastic Traceroute TX/RX, with T-Beam, average across 5 samples+3.75dB TX / +2.8dB RX
