SwellPro HHQ Wireless Megaphone for SplashDrone SD3+

SKU CH-M4QD-B9QMC

A wireless megaphone for SplashDrone SD3+ with a 100W amplifier, 2km transmission range and 40m audio reach

  • Real-time voice and pre-recorded messages broadcast from the drone
  • Wireless audio transmission reaches 2 km between megaphone and base station
  • Built-in FPV camera provides live visual monitoring during flight
  • 100 W waterproof amplifier projects sound clearly up to 40 m
  • Effective communication at 30 m altitude for public address tasks

Designed for SplashDrone SD3+

The SwellPro HHQ Wireless Megaphone is an all-weather, waterproof module built specifically for the SplashDrone SD3+. It combines a high-quality colour camera with a 100-watt waterproof remote loudhailer for real-time observation and clear audio delivery. The system includes a paired UHF base station for long-range wireless transmission. It transforms the drone into a portable tool for public broadcasting or crowd control.

Suits public safety and commercial operators

This megaphone serves law enforcement, marketing teams and emergency scene managers who need to broadcast live or pre-recorded messages, tones or music from an altitude of 30 metres. The effective audio range reaches 40 metres in most scenarios. It is not suited for users who require two-way communication, indoor-only operation, or a megaphone compatible with other drone platforms.

Mounts on SplashDrone SD3+ airframe

Installation involves attaching the waterproof module to the SplashDrone SD3+ and pairing it with the supplied UHF base station. Wireless transmission operates up to 2 kilometres between the megaphone and base station. The main difficulty is ensuring secure mounting and correct frequency pairing before flight; improper attachment can cause signal loss or detachment during operation.
