High Gain Foldable Omnidirectional Antenna For Wireless Transmission System 423 To 443 MHz, Portable SMA Male Drone Antenna, Beefed Up Signal Booster, 5 Pack

Foldable 423-443 MHz 6dBi SMA Antennas 5 Pack for Drone Signal Boost
✔️ Frequency range 423 to 443 MHz with 6 dBi gain and SMA male plug

These foldable antennas deliver reliable signal transmission and boost for wireless systems including drones and smart home setups in the specified frequency band.

✅ 423-443 MHz working frequency for targeted bands
✅ 6 dBi gain with vertical polarization
✅ SMA male connector rated for 50W max power
✅ ABS material with -40 to 85 C operating range
✅ Pack of 5 units for multiple device installs

💡 Why does a standing wave ratio below 1.5 matter for SMA male antennas in wireless data modules? This ratio keeps signal reflections low so more power reaches the intended receiver. - Vertical polarization pairs well with common receiver orientations - 50 ohm impedance matches standard transmission lines easily - Independent channel use cuts down on interference issues - Supports steady gain across drone and alarm system installs
