RFXCOM 433.92 MHz Antenna with Magnetic Base (1m Cable) | SMA Connector

RFXCOM 433 MHz Antenna with Magnetic Base & 1 Meter Cable (SMA)

Easily expand the transmission and reception range of your RFXCOM transceiver with this external 433 MHz antenna with magnetic base and 1-meter coaxial cable. Are you experiencing problems with intermittent Somfy RTS roller shutters, missed weather station signals, or range issues around the house? This antenna allows you to place the transmitting element in the ideal spot, away from interference and obstructions.

⚠️ Note the connector: This antenna features a standard SMA connector and is directly compatible with the RFXCOM RFX-433EMC Transceiver and other 433 MHz equipment with an SMA connection.

Why does this external antenna significantly improve range?

In practice, the RFXCOM transceiver is often located in a place where radio signals struggle: in the meter cupboard, behind a TV cabinet, amidst a tangle of cables, or right next to Wi-Fi routers, power supplies, and NAS systems. All these devices and walls absorb or interfere with the 433.92 MHz signal.

Thanks to the 1-meter coaxial cable and the strong magnetic base, you can solve this in one go:

• Placement outside the interference environment: With the 1-meter cable, you can easily place the antenna outside the meter cupboard or interference zone, freely in the room. This greatly improves radio signal reception and transmission. In practice, this yields the biggest range improvement!
• Strong magnetic base: Easily attach the antenna to a metal surface (such as the outside of a distribution box or a metal bracket). A metal surface also acts as a reflector (ground plane), which further enhances signal coverage.
• Suitable for indoor and outdoor use: Thanks to its robust construction, the antenna can be mounted both indoors and sheltered outdoors.

Frequently Asked Questions (FAQ)

Why does this antenna with cable help if my RFXCOM is in the meter cupboard?

The meter cupboard contains many power cables, smart meters, and often your internet modem/router. This causes a lot of electronic noise. With the 1-meter cable, you can easily lead the antenna out of the meter cupboard to a clear spot, significantly increasing the transmission and reception range.

What is the magnetic base for?

The magnetic base ensures that the antenna stays firmly on metal surfaces. In addition, a metal surface helps reflect the radio signal, which further improves the antenna's performance.

Is this antenna easy to install?

Yes, plug-and-play. You simply screw the SMA connector of the cable onto the antenna connection of your RFXCOM transceiver. No additional software or configuration is needed.
