The H169-SMA is a 169 MHz helical antenna designed for us on ISM-band terminals especially in the European metering frequency band
The H169-SMA is a 1/4 wave 169 MHz helical antenna tuned with a centre frequency at 169 MHz. It is housed in a flexible moulded sheath and is terminated in a SMA-Male connector. Other connectors can be used, subject to a minimum order quantity.
Designed with the EU unified licensed band at 169 MHz, the H169-SMA is suitable for metering and similar applications. The antenna has an overall length of approximately 140mm and a diameter of 13.5mm.
The antenna should be mounted onto a suitable groundplane for optimum operation.
Other VHF frequency bands are possible and a variety of other connectors are possible too including RP-SMA, TNC, RP-TNC, BNC.
