Câu hỏi thường gặp
Q: Why is this amplifier cheaper than your other COFDM amplifiers?
Một: This is the peak power. For our digital amplifier, we calculate it based on the average power, not the peak power. And for this PA, it can’t have such an average power and such a wide range. If it is such a wide range, it must be a small power.

This RF amplifier is a game-changer for our field operations! Its phenomenal 45-1100MHz bandwidth eliminates dead zones across UHF/VHF bands, while the switchable 4W/5W output adapts instantly to terrain challenges. Powered by universal 24V DC, it integrates seamlessly with our vehicle/solar setups – no voltage headaches. Signal clarity improved dramatically: weak drone telemetry feeds now hit 8km reliably, and broadcast links cut through urban interference like butter. The rugged aluminum housing survived desert heat, downpours, and tower vibrations. After wasting months on underpowered amps, this tank-like workhorse delivers set-and-forget reliability with zero distortion. A must-have for drone pilots, broadcasters, and critical comms teams
