What makes our boosters different?

1. Equipped with an advanced DSP for high-efficiency signal processing.2. Delivers radio spectrum performance that surpasses industry standards.3. Features a unique intelligent decision-making system that adapts in real time to on-site signal strength, creating professional-grade signal boosters with exceptional reliability.

5-level signal filtering effectively eliminates noise and out-of-band emissions, preventing interference to cellular base stations.

1. RADIO EMC EMF SAFETY tests verify no harm to human health and no interference to cell stations.2. Radio Equipment Directiive CE certified. Ofcom Exemption.

Automatic standby mode when idle, energy-efficient and long-lasting performance.

How to install the booster kit?

1. Find a strong outdoor signal sourceChoose an open area outside your property, preferably at a higher elevation (e.g., rooftop). Place the outdoor antenna by type:A - Directional antennas (LPDA, Yagi, Panel): Point directly toward the cell tower, with no obstacles nearby.B - Omni-directional antenna (Pipe antenna): Point vertically toward the sky, with no obstacles nearby (cell tower direction is irrelevant).2. Connect the outdoor antennaUse the 15-meter cable (or sufficient length) to connect the outdoor antenna to the “Outdoor ANT” port on the booster.3. Place and connect the indoor antennaPosition the indoor antenna in the central area of the target coverage zone, keeping it clear of obstacles. Use the 5-meter cable (or sufficient length) to connect it to the “Indoor ANT” port on the booster.4. Power on the booster. Check the LED indicators on the booster to confirm normal operation (refer to LED State Explanation below).

Power LED

Green – Power ON (normal)

Dark - No power supply

Down Link LED (DL/P) - Signal Amplification Status

Dark - No signal received

Blue - Weak signal received, working.

Green - Good working state

Bright Red - Optimal working state.

Up Link LED (UL/P) - Calling & Alarm Status

Dark - No calls, standby state

Flicker - Calls/internet active, working state

Solid Red - Alarm, check installation.

What to do in ALARM state - Turn off the booster, check installation per the troubleshooting section in the full user manual. The booster will resume normal operation automatically after the issue is resolved.

We are very happy with the purchase. From 1-2 bars inside the house and 4 bars at best outside, we now can manage our calls effectively, send and receive emails. We are living the dream. Great product right there!

I bought this unit because a friend convinced me to not because I really wanted to so once it was delivered I was a bit skeptical if it would actually work. Luckily for me, it did, and I owe him big time.
