The MH433 is a 433 MHz quarter wave helical antenna designed for ISM band devices with metal enclosures or proximity groundplanes
The MH433 is a 433 MHz quarter wave helical antenna based on an injection-moulded helical ¼ wave design and operates with a centre frequency of 433 MHz. Suitable for ISM-based terminals operating in the licence-free band, the MH433 is small enough to mount onto mobile or portable devices as well as fixed terminals.
It is approximately 75mm in length with a flexible sheath and has a SMA-Male connector as standard. Other connectors such as TNC or BNC can be supplied (minimum order quantities may apply) and also other frequencies are possible, typically from 150 MHz to 480 MHz. The length of the antenna will vary depending on the centre frequency specified.
The MH433 sits alongside the MW433 whip antenna in our portfolio of 433 MHz solutions.
