Built from UV-stabilized outdoor polymers with storm-sealed cabling and instant visual telemetry.
Two tall omni-directional HighPower 300Mbps antennas lock parallel with a center stabilizer clip to prevent wind whip in heavy gusts.
The threaded bottom sealing cap compresses tightly around your Ethernet jacket so driving rain and humidity never reach the RJ45 port.
Three graduated green signal bars plus Wi-Fi, WAN/LAN, and POWER lights let you aim on the ladder and check status from the driveway.
Integrated heavy-duty side loops strap cleanly to PVC masts, wooden 4x4 fence posts, house eaves, or RV rear ladders in seconds.
Indoor 5GHz pucks choke behind Low-E glass and brick veneer. Placing dual HighPower 2.4GHz omni antennas in clear outdoor air bends signal cleanly through trees, wooden barn siding, and detached metal workshops.
Cheap porch setups fail when summer humidity corrodes open ports. Your Ethernet line feeds straight up through a multi-ribbed threaded bottom sealing cap that locks moisture out through year-round thunderstorms.
Wire it to your main router in AP Mode for a dedicated backyard SSID, or run Repeater Mode on a distant outbuilding or RV ladder while watching the 3 top green LED bars confirm peak signal strength.

Swipe left for steps 2 and 3
Screw both tall white 2.4GHz rod antennas onto the top connectors and snap the horizontal bridge clip between them so they stand strictly parallel.
Feed your Ethernet cable up through the ribbed bottom sealing cap, click it into the recessed WAN/LAN port, and twist the weatherproof cap tight.
Select AP or 2.4GHz Repeater mode on 192.168.10.1, strap the four side loops to your eave, post, or RV ladder, and verify green LED signal bars.
Mounted it on the corner of my detached garage and ran Ethernet through the ribbed bottom cap. The four side loops zip-tied neatly to a PVC mast. Green LEDs came right on, and 2.4GHz coverage now reaches our patio and cameras.
I wanted a wired connection from the router that could broadcast Wi-Fi outdoors, and AP mode did exactly that. The Ethernet cable enters through the weatherproof bottom gland, and both my backyard cameras and phone now stay connected without random drops.
Needed an affordable 2.4GHz repeater for my workshop about 150 feet away. The bridge clip keeps the two tall antennas steady in windy weather. Its N300 connection has been plenty for streaming music and running several smart plugs.
The campground Wi-Fi barely reached our windshield, so I strapped this white cylinder to the rear ladder using all four mounting loops. Repeater mode works well, and the six green front LEDs made finding the best position surprisingly easy.
This has survived two months of heavy thunderstorms without a hiccup. The glossy hard-plastic housing feels solid, and the screw-on ribbed cap seals snugly around the cable. We now have dependable coverage around the pool and dock.
We use it for smart feeders and cameras in our horse barn. The 2.4GHz signal handles trees and wooden siding better than our 5GHz network did. POWER, WAN/LAN, and Wi-Fi lights make status easy to check from the driveway.
Our cameras at the far end of the property constantly buffered. I installed this under the eaves in wired AP mode, and they now show full bars. It won't exceed your internet plan, but it extends the existing connection very reliably.
Assembly took maybe five minutes. I screwed on both white antennas, snapped the H-shaped bridge clip between them, and fed Ethernet through the bottom cap. Setup at 192.168.10.1 was straightforward after choosing Repeater mode.
Our indoor mesh signal stopped at the brick patio wall. I wired this outdoor AP to the main network and created a dedicated 2.4GHz yard SSID. Everyone by the pool now gets full bars without relying on signal through brick.
The glossy white cylinder blends nicely with our white fence post. Its dual 2.4GHz antennas cover a surprisingly large open area, and the top three green signal bars helped me choose the best spot before tightening the mounting ties.

Yes. Selecting Access Point (AP) Mode lets you run a wired Ethernet connection up through the weatherproof ribbed bottom sealing cap and broadcast a fresh, full-strength 2.4GHz outdoor Wi-Fi network across your yard, patio, and cameras.
Yes. In Repeater Mode, you can mount the cylinder on a detached garage mast, barn gable, or RV rear ladder (powered locally over its Ethernet drop) to capture an existing 2.4GHz Wi-Fi signal and rebroadcast it farther out.
Absolutely. You can either wire it to one of your mesh nodes in AP Mode with its own dedicated outdoor network name, or set it to Repeater Mode locked onto your router's dedicated 2.4GHz band so mesh band-steering never confuses it.
The unit uses a glossy UV-stabilized vertical shell paired with a threaded, multi-ribbed bottom sealing cap and rubberized cable grommet. Once screwed tight around your Ethernet cable, moisture cannot reach the recessed RJ45 port.
Look directly at the vertical green LED column on the front housing. Above the POWER, WAN/LAN, and Wi-Fi lights sit 3 graduated green signal-strength bars that light up live so you can aim and verify reception before tightening your straps.
No extender increases your ISP plan speed. Equipped with a 100Mbps WAN/LAN port and a 300Mbps 2.4GHz HighPower radio, the AeroMast N300 is engineered to relay a steady, full-bar connection 150+ feet into dead zones where indoor 5GHz routers drop to zero.
