1.2GHz FPV VTX Low Pass Filter (12LPF)

If your 1.2GHz long-range video feed is turning your 2.4GHz control link into an uncooperative, twitching mess, congratulations: you forgot that RF harmonics exist. The 12LPF 1.2GHz Low Pass Filter is the no-nonsense cure for self-inflicted radio frequency interference. Plumbed directly between your 1200MHz–1390MHz FPV video transmitter and antenna, this monolithic LC multi-pole filter savagely nukes second-harmonic bleed (>35dB attenuation at 2.4GHz) before it can murder your RC control signal or cause servo jitter. Stop blaming solar flares for your failsafes and filter your RF stack properly.

Highlights

• Killer 2.4GHz Suppression: Slams the brakes on second-harmonic noise with >35dB attenuation, keeping your 2.4GHz receivers pristine.
• Minimal Signal Penalty: Extremely low insertion loss (under 0.7dB typical at 1300MHz) so your long-range video retains its punch.
• 8W RF Power Rating: Easily handles high-power video transmitters without saturating or burning up.
• Inline SMA Connectors: Fitted with standard SMA male to female ports for effortless, zero-cable integration.

Why You Want It

Flying long-range 1.2GHz video alongside 2.4GHz control links without a low pass filter is an invitation for erratic servo jitter and random failsafes. The 12LPF cleans up dirty harmonic emissions at the source, ensuring crystal-clear video output and rock-solid control response without sacrificing your output power.

FAQ

Will this low pass filter reduce my 1.2GHz video range?

Not noticeably. With a typical insertion loss under 0.7dB at 1300MHz, the drop in power is negligible compared to the massive reduction in control link interference.

Where should I install the 12LPF filter?

Screw it inline directly between your 1.2GHz video transmitter's SMA output port and your video antenna for optimal noise suppression.
