The narrowband 868 MHz antenna helps to fight out-of-the-band noise

This antenna was designed for 868 MHz radio equipment operating in noisy environment. Very often such radio equipment uses a single-chip transceivers in the front-end, that is less immune for out of the band noises and interferences due to the power restrictions.

Usually the first amplifier in the RF chain, does not have a high IP3 that is a figure of merit of intermodulation performance or receiver linearity for active RF devices.

In other words it can be blocked easily by out-of-the band RF signals. TetraAnt 868 08 70 because of it's narrowband nature, is the first stage 868 MHz filter and helps to lower out-of-the band signals level. Hence, a front-end RF circuit of the transceiver will be more immune to the RF signals outside the operational band.
