Indoor 9dBi Omnidirectional Antenna

The ALFA ARS-N19 is an indoor omnidirectional antenna offering 9dBi gain at 2.4GHz. It connects via an RP-SMA connector and presents a 50 Ohm impedance for compatible wireless equipment. The unit ships new in its box with all relevant accessories included.

Suitable for fixed indoor wireless links

This antenna suits users extending a single 2.4GHz connection inside a building where an omnidirectional pattern is acceptable. It is not for buyers who need outdoor-rated hardware, directional gain, multiple simultaneous channels, or operation beyond the 10 Metres maximum range stated.

RP-SMA connector and 2.4GHz band

The RP-SMA interface determines whether the antenna fits your device; verify the port on your router, adapter or access point before purchase. The 2.4GHz operating band is the other deciding specification for compatibility.

Questions about this item

Does the RP-SMA connector or antenna element need periodic replacement?

The antenna is a passive dipole with no moving parts or consumable elements, so no scheduled replacement is required for the connector or radiating element.

What limits continuous operation of this 9 dBi omni antenna?

As a passive component it has no thermal or power ceiling; the practical limit is the 10 metre maximum range stated for the 2.4 GHz band.

Does the antenna generate any noise or heat when used all day?

It is a completely passive device with no electronics, so it produces zero audible noise and no measurable heat during continuous operation.
