For the Toughest Use: Your IP67 WiFi Antenna
When standard Antennas reach their limits, this Antenna is just getting started. Developed for relentless continuous use in industry, logistics, and outdoor areas, the CA-2458-02-BLACK offers you absolute reliability. The housing is not only IP65 certified (protection against jet water) but even meets the strict IP67 standard. This means: completely dustproof and protected against temporary submersion. Whether on a truck, an outdoor control cabinet, or an unprotected machine hall – this Antenna delivers where Others give up.
Dual-Band Power: Flexible in 2.4 & 5 GHz Network
Why choose one frequency band when you can have both? This antenna is a true Dual-Band Omni-Directional Antenna for vehicles and trucks and supports all common WiFi standards from 802.11a to 802.11ac. Use the long-range 2.4 GHz band for maximum coverage or switch to the often faster and less interference-prone 5 GHz band. With an antenna gain of 5 dBi in the 5 GHz range, you get maximum performance from your Network – ideal for data-intensive M2M / IoT Antennas.
Rock-Solid Mounted: Secure on Vehicle & Housing
A good antenna must not only transmit well but also hold securely. The well-designed ceiling or housing mounting (Roof Screw Mount) ensures a rock-solid and permanent connection. With the 2.5 cm long plastic thread and the included lock nut, you can securely fasten the antenna, preventing tampering. An additional rubber seal at the base reliably protects the bore from penetrating moisture. This makes it the perfect IP67 WiFi Antenna for control cabinet mounting.
Universally Compatible: The RP-SMA Standard Connector
No complicated adapters, no compatibility issues. The antenna comes with a 30 cm long, permanently attached Coaxial Pigtail Cable of the low-loss CLF100 type. At the end is a widely used RP-SMA Connector (Reverse Polarity SMA). This connector is used by countless WiFi Routers, WiFi Access Points, IoT Gateways, and embedded systems. Simply screw it on and immediately benefit from a better signal.
Strengths & Notes at a Glance
- Pro: Extremely robust and weatherproof according to IP67 for the most demanding environments.
- Pro: True Dual-Band Performance with strong 5 dBi gain in the 5 GHz band.
- Pro: Secure and waterproof screw mounting for fixed installations.
- Pro: High compatibility due to the widely used RP-SMA connector.
- Note: The 30 cm Cable is permanently installed; a high-quality extension is required for longer distances.
- Note: Not suitable for MIMO setups as a single antenna; two Antennas are required for this.

Frequently Asked Questions (FAQ)
Can I easily mount this antenna outdoors on my vehicle or a hall?
Yes, absolutely! This antenna is super robust with IP67 protection. This means it's completely dustproof and can even withstand brief submersion. Rain, snow, or harsh industrial environments won't affect it at all. Mount it wherever you need it for your Network!
What exactly is an RP-SMA connector and will it fit my router?
RP-SMA is a common Coaxial Connector for Antennas. Just take a look at the antenna jack on your WiFi Router: Does it look like a small thread with a hole in the middle? Perfect, then you can screw this antenna directly onto it. Many well-known WiFi Routers, for example from AVM, use exactly this connector.
I want better WiFi in my workshop. Will this antenna help me with that?
Yes, it's perfect for that! As an Omni-Directional Antenna, it distributes the WiFi signal evenly in all directions (360°). It's best to mount it centrally on the ceiling of your workshop. This way, you'll optimally supply all your devices and bypass many obstacles on the ground.
What does an antenna gain of 3 and 5 dBi mean for my WiFi?
Simply put: More power for your signal! Compared to your router's standard WiFi Antennas, this gain provides a stronger and more stable connection. Especially in the 5 GHz Network, the higher 5-dBi gain gives you better range and fewer disconnections.
The cable is quite short at 30 cm. Can I easily extend it?
Yes, you can, but pay attention to the quality! You'll need a special, well-shielded Antenna cables extension cable with RP-SMA Coaxial Connectors. Remember: every extension attenuates the signal a little bit. So, choose the shortest length necessary to ensure the best performance for your WiFi.
Does this antenna also work for 5G mobile reception?
No, absolutely not. This antenna is a pure WiFi specialist and built only for 2.4 GHz and 5 GHz frequencies. 5G mobile communication operates on completely different bands. Therefore, you wouldn't get any reception with it.
