The 60dB SMA Attenuator (DC–8GHz) is designed for safe RF power reduction during bench testing and pre-flight ground range tests. By reducing transmitter output power by 60dB, it allows you to verify control link and video performance at close range without overloading receivers.
This makes it ideal for simulating long-distance conditions while standing only a few metres away — particularly useful when checking failsafe behaviour, RSSI response, and general link stability before flying.
With a broadband DC–8GHz rating, it covers common FPV and RC frequencies including 1.2GHz, 2.4GHz, and 5.8GHz. The 50Ω impedance and low VSWR ensure proper RF matching during testing.
Typical uses:
- Ground range testing FPV VTX systems
- Testing ELRS, Crossfire, Tracer and other 2.4GHz control links
- Preventing receiver overload during bench diagnostics
- Simulating long-range signal attenuation safely
- Frequency Range: DC – 8 GHz
- Impedance: 50Ω
- Power Rating: 2W (+33dBm)
- Attenuation: 60dB (±2dB max)
- VSWR: ≤ 1.25:1
- Connector Type: SMA Male to SMA Female
Note: Some systems (e.g. Tracer) require an RP-SMA male to SMA female adapter — available in the add-on section.
