The Perfect 90° Solution for Tight Spaces
Do you know the feeling? Your WiFi Router is too close to the wall or in a cramped Network cabinet, and the Antenna Cable sticks out stiffly. A severely kinked Cable is not only unsightly but can also significantly impair signal quality and eventually get damaged. With this 90° angled Coaxial Adapter, you solve this problem elegantly and professionally. It enables space-saving and clean Cabling, protects your equipment, and ensures optimal alignment of your Antennas.
Loss-Free Signal Transmission for Your Network
Every additional connection in the signal path is a potential weak point. That's why the highest value was placed on quality for this Coaxial Adapter. With a minimal insertion loss of only about 0.5 dB and an excellent Standing Wave Ratio (VSWR) of maximum 1.25:1, your signal is transmitted almost loss-free. This is crucial for demanding applications like 4G / 4G, 5G, or high-performance WiFi, where every decibel counts to maximize range and stability.
Robust Design for Maximum Durability
This Coaxial Adapter is built for continuous use. The housing is made of solid brass and is completely gold-plated. This not only looks high-quality but, more importantly, offers two decisive advantages: an excellent electrical conductivity and reliable protection against corrosion. The internal PTFE insulator and the gold-plated beryllium-copper contact guarantee a mechanically and electrically stable connection with exactly 50 Ohm, even after frequent plugging and unplugging.
Compatibility Made Easy: RP-SMA Meets SMA
The world of RF connectors can be confusing. This Coaxial Adapter builds the crucial bridge between the two most common standards. It connects an RP-SMA Male to SMA Female. Pay close attention to the connectors: The RP-SMA Male has an internal thread and a hole in the center (cup), while the SMA Female has an external thread and a pin. This Coaxial Adapter fits perfectly in between and is ideal for operating, for example, a professional Antenna with a standard WiFi Router like a FRITZ!Box.
Strengths & Notes at a Glance
- Pro: Solves space problems in tight spots and prevents kinking of Antenna cables.
- Pro: High signal quality due to very low insertion loss of only approx. 0.5 dB.
- Pro: Extremely durable and corrosion-resistant thanks to gold-plated brass housing.
- Pro: Bridges the incompatibility between RP-SMA (WiFi) and SMA (Mobile/Measurement Technology).
- Note: Every plug connection is a potential source of error. Ensure a firm fit to avoid signal reflections.
- Note: Risk of confusion when ordering! Carefully check if you need RP-SMA to SMA to prevent a non-functional connection.

Frequently Asked Questions (FAQ)
Does this adapter also fit my FRITZ!Box WiFi Router?
Yes, absolutely. Most common WiFi Routers, like your FRITZ!Box, use RP-SMA jacks. You simply screw this adapter directly onto your router's antenna connector to then connect an antenna with a professional SMA plug.
Will I lose signal strength due to the 90° angle?
Don't worry, the angle itself has no measurable impact on your signal strength. The quality of an adapter depends on its attenuation. With only about 0.5 dB, the loss with this adapter is so minimal that you won't notice any difference in practice.
What material is the adapter made of, and can I use it outdoors?
The adapter is made of robust, gold-plated brass with a high-quality PTFE insulator. This makes it super durable and protects against corrosion. However, it's intended for indoor use or protected outdoor areas, as it doesn't have a special seal against water.
What does '50 Ohm' mean, and is it important for me?
Yes, that's extremely important for you! 50 Ohm is the standard characteristic impedance for almost all WiFi, mobile communication (4G / 5G Routers), and radio systems. To avoid signal losses due to reflections, all your components – meaning antenna, Cabling, adapter, and device – must have the same 50 Ohm.
How tight should I fasten the adapter? Do I need tools for it?
For the best connection, first tighten the adapter hand-tight. Then, give it a very slight turn with a suitable small wrench (usually 8 mm), about an eighth of a turn. But beware: too tight can damage the connector, too loose weakens your signal.
Help, I've connected the wrong connectors and the signal is bad. Why is that?
That happens! Even though there's no direct contact, the signal can 'jump' at such a small distance. However, this leads to an extremely poor and unstable connection. Be sure to use this adapter to establish a clean electrical connection and protect your device.
