RUSHFPV 3.1G - 3.8G Ultra-wideband Receiver Antenna Kit for FPV, Fixed-wing and RC Aircraft | Mechfpv of Shenzhen

description: The RUSHFPV XSPAN 3.1G‑3.8G is a complete analog ground‑station receiving kit designed for long‑range FPV multirotors, fixed‑wing UAV and RC aircraft. It covers ultra‑wide frequency bandwidth from **3100‑3800 MHz**, built for pairing with RUSHFPV XSPAN high‑power VTX for long‑distance analog video downlink. This analog VRX features high‑sensitivity RF front‑end with receiving sensitivity up to ‑95 dBm, CNC‑machined aluminum alloy housing for EMI shielding and thermal stability. Channel tuning is completed via rotary adjustment knob with printed channel reference table on housing for quick field setup. It outputs standard PAL / NTSC CVBS analog video & mono audio signal, compatible with external monitors, FPV goggles and DVR recording devices. Wide DC input 7‑30 V supports 2‑6S LiPo power supply. The included ultra‑wideband circular‑polarized SMA antenna fully covers the whole 3.1‑3.8 GHz spectrum. This kit provides excellent anti‑interference performance and avoids conflicts with 2.4 GHz ELRS control links, ideal for long‑range cross‑country FPV missions. > Note: This product is analog CVBS receiver, works only with 3.1‑3.8 GHz analog VTX transmitters. This frequency band is mainly for export‑only use, please comply with local radio‑communication regulations. brand: RUSHFPV sku: RUSH‑XSPAN‑31‑38G‑VRX‑KIT offers: • Ultra‑wide operating frequency: 3100‑3800 MHz for long‑range analog FPV reception • High receiving sensitivity: ‑95 dBm for reliable weak‑signal performance • CNC aluminum alloy housing for EMI shielding & mechanical durability • Rotary knob channel adjustment with printed channel reference chart on casing • Complete kit: VRX ground receiver + matched 3.1‑3.8G circular polarized wide‑band antenna • SMA‑50Ω antenna interface; PAL/NTSC CVBS analog video + mono audio output • Wide DC 7‑30 V power input (2‑6S LiPo compatible) • Optimized for long‑range multirotor, fixed‑wing UAV and RC aircraft projects • Excellent anti‑interference, avoids interference with 2.4 GHz ExpressLRS control links availability: In Stock, Fast Shipping
