Gain Selection Guide - Please Read Before Installation
Choosing the correct gain setting is crucial for optimal system performance and to prevent overload. Follow this guide based on your setup:

With Long Cable or Splitter: If using a long RF cable (over 5 meters) or a power divider between the amplifier and your hotspot, use the RX = 17dB, TX = 6dB combination (this product's default).
Direct Connection: If connecting the amplifier directly to your hotspot with a short cable, we recommend using a lower gain model, typically RX = 10dB, TX = 0dB.
Testing & Adjustment: To evaluate the impact of different gains, start with RX=17/TX=6 and use external 3dB or 6dB attenuators to fine-tune.
Other Gain Combinations: Need a different RX/TX gain value? Please contact us for custom options.

DESCRIPTION
Optimize your indoor Helium or LoRaWAN gateway with the ACASOM 868MHz Amplifier. This unit features a fixed 17dB receive gain and 6dB transmit gain, ideal for compensating signal loss in systems with longer cable runs or signal splitters. A key advantage is the integrated SAW filter in both the Rx and Tx paths, which provides essential out-of-band interference rejection to improve signal clarity and system stability. Powered by a standard DC plug (6-18V), this compact and efficient amplifier is designed to enhance coverage and reliability for your 863-870MHz IoT network.

KEY FEATURES

Optimized Fixed Gain: Preset to RX=17dB / TX=6dB, ideal for setups with significant cable loss.
Built-in Interference Protection: Features SAW filters on both receive and transmit chains to reduce unwanted noise.
Simple Power Setup: Operates via an included DC power plug for easy and reliable installation.
Clear Status Indicators: Dual LED indicators (Green for TX, Red for RX) provide instant visual feedback on operating mode.
Compact Metal Housing: Durable aluminum shell ensures effective heat dissipation and RF shielding.
