产品概述
The Shrimp B 3.3G 4W VTX is a high power FPV video transmitter built for long range FPV and long range drone builds. Operating on the lower-interference 3.3GHz band, this 3.3G video transmitter covers 3060–3495MHz across 64 channels with dedicated 3.3G frequency bands, giving pilots cleaner analog video signal at distance than crowded 5.8G setups.
Output is switchable PIT / 25mW / 200mW / 1W / 4W — a true 4W VTX / 4000mW class module for long range FPV video transmission. FM modulation with PLL frequency control keeps channels locked, and full IRC Tramp protocol support lets you control power and bands from your flight controller and goggles. The 3.3G VTX accepts DC 7–30V (2–8S), ships with an SMA 50Ω antenna interface, and weighs only 25.3g, so it fits most rc drones and FPV drone builds.
- 01True 4W / 4000mW output power — a high power 3.3G VTX that takes long range FPV video transmission to a new level.
- 0264 channels from 3060–3495MHz with dedicated 3.3G bands (3330–3470MHz / 3170–3310MHz) for cleaner analog long range video.
- 03IRC Tramp protocol with FM + PLL frequency control — set power and channels straight from your FC or goggles.
- 04Wide DC 7–30V (2–8S) input with PIT mode and SMA 50Ω antenna interface; featherweight 25.3g fits most FPV drone builds.
- 05Purpose-built for long range drone builds — a 3.3GHz analog VTX that pairs with 3.3G VRX and RHCP antennas for extended-range setups.
