Dual-band directional panel antenna
The ALFA APA-M25 is a dual-band 2.4/5 GHz directional patch antenna built for indoor use. It connects to any Wi-Fi receiver or router with an RP-SMA port and supports 802.11 ac equipment. The design suits fixed installations where a focused signal path is required.
Gain, beam width and VSWR
The antenna delivers 8 dBi gain at 2.4 GHz and 10 dBi at 5 GHz. Vertical beam width measures 16 degree and horizontal beam width 66 degree. VSWR is rated at 2.0:1 maximum with linear vertical polarization across the 2.4-2.5 GHz and 5.150-5.875 GHz ranges.
RP-SMA connector and form factor
A male RP-SMA connector provides direct attachment to compatible Alfa hardware such as the AWUS036AC. The panel measures 167.3 x 66 x 18 mm and weighs very little for simple mounting. No additional cables or software are bundled with the unit.

Questions about this item
How do I attach the RP-SMA male connector to my router and what alignment mistake should I avoid?
Screw the RP-SMA male plug onto the router's RP-SMA female port until finger-tight, then aim the panel's front face toward the target area because the 66-degree horizontal and 16-degree vertical beam widths mean signal drops sharply off-axis.
What upkeep does the APA-M25 need over time?
No electronic maintenance is required; occasionally check that the RP-SMA joint stays snug and wipe the black radome with a dry cloth if dust builds up, as the sealed patch element has no moving parts or filters.
What physical limit appears first when the antenna runs continuously in a hot attic?
The VSWR rating of 2.0:1 maximum is the first RF limit reached if temperature drifts the patch tuning, while the 167.3 x 66 x 18 mm housing has no active cooling to offset ambient heat.
