AUTECH 3dBi RP-SMA Antenna Four-Pack

This set of four dual-band antennas covers 2.4 GHz and 5.8 GHz frequencies with 3 dBi gain. The RP-SMA male connectors fit routers, USB adapters, PCIe cards and IP cameras. They are designed for omni-directional coverage in home, office or mobile installations.

Sustained signal stability across both bands

The omni-directional pattern maintains consistent gain whether the link is a router-to-client hop or a long-range FPV video feed. Performance does not rely on short bursts; the antennas hold their 3 dBi figure across the full 2400-2485 MHz and 5150-5850 MHz ranges during continuous streaming or surveillance recording.

Passive operation with no added heat or noise

As purely passive elements the antennas draw no power and generate no heat of their own. They add no audible noise to the system and impose no extra load on the host device power supply. The only physical requirement is an RP-SMA female port on the equipment.

Questions about this item

How much heat does the 3dBi antenna generate when left on a router all day?

The antenna is a passive component with no power supply, so it produces no measurable heat during continuous operation.

What connector must my router or adapter already have for these RP-SMA male plugs to fit?

Each antenna needs a female RP-SMA jack — check that your device shows a centre hole without a pin before buying.

Will the 2.4 GHz and 5.8 GHz coverage work with my older single-band 2.4 GHz router?

The antenna radiates on both bands, but a 2.4 GHz-only router will only use the 2400–2485 MHz portion of its range.
