Alfa Panel Indoor Antenna APA-M25 | Dual-Band 2.4/5 GHz Wi‑Fi Panel Antenna, 8/10 dBi, RP-SMA

APA-M25 is a dual-band high-gain indoor panel antenna designed for operation in the 2.4 GHz and 5 GHz bands. It covers 2.4 to 2.5 GHz and 5.150 to 5.875 GHz, allowing one antenna to serve both supported frequency ranges instead of requiring separate single-band units. The antenna uses a patch directional design, concentrating its radiation pattern in a defined direction rather than distributing energy equally around the installation point. This makes placement and orientation important parts of deployment, because the antenna is intended to focus coverage toward a chosen area. The same panel can therefore be used in installations operating on either supported band, simplifying antenna selection for dual-band equipment.

Gain is rated at 8 dBi in the 2.4 GHz band and 10 dBi in the 5 GHz band, giving the antenna a higher stated gain at 5 GHz. Linear vertical polarization defines the required antenna orientation relative to other vertically polarized wireless equipment. The specified beamwidth is 16 degrees vertically and 66 degrees horizontally, creating a comparatively narrow vertical pattern with a broader horizontal spread. This directional profile can help installers aim the antenna toward the intended coverage zone while limiting unnecessary radiation outside that orientation. A maximum V.S.W.R. of 2.0:1 defines the stated impedance-matching performance across the supported frequencies.

The APA-M25 uses an RP-SMA Plug (Male) connector, providing the RF interface for attachment to compatible wireless equipment or cabling with the corresponding connector type. Its panel format measures 167.3 × 66 × 18 mm, giving installers the enclosure dimensions needed when planning placement in an indoor setup. The compact rectangular form allows the antenna to be incorporated into installations where the available mounting area must accommodate a panel measuring approximately 167 mm in height and 66 mm in width. Its 18 mm depth also provides a clear reference when determining the space required around the antenna body and connector during installation.

The antenna’s radiation characteristics are defined in the XY, YZ, and ZX planes for the supported frequency ranges, providing information about how signal energy is distributed around the panel. At 2.4 GHz, patterns are shown for 2400, 2450, and 2500 MHz, while the 5 GHz characteristics cover multiple points across the supported band up to 5875 MHz. These patterns illustrate that the antenna response changes with direction and frequency, which is relevant when deciding how the panel should be positioned within an indoor installation. Together with the defined connector type and enclosure dimensions, these characteristics give installers the key information needed to plan physical placement, antenna orientation, and connection to compatible RF equipment without relying on an omnidirectional installation approach.
