The RF Electrosmog sensor is a broad bandwidth RF detector. It can detect RF over the frequency range 50 MHz to 3 GHz.

This means it is suitable for measuring the RF that comes from Bluetooth, Wi-Fi, microwave ovens and mobile phones. The detector does not distinguish the frequency of the RF source, some discrimination of frequency can be achieved with design of the antenna.

The RF Electrosmog sensor is fitted with a female F - type connector (the type of connector used for cable and satellite aerial connections). The F - type connector allows the user to make and attach antennae that are more specifically tuned to a particular frequency.

See the RF Transmitter Keyfob (3158) that we used in the antenna and distance experiments (available from the Resources tab).

• One antenna (ANT1) cut to 31mm, the ¼ wavelength of 1.8 GHz (mobile phone frequency).
• A 0.5 metre length of coaxial cable.
• 2 screw on F - connectors.
