TetraAnt 868 08 70
Antenna designed for radio modems and active RFID systems operating in the 858-878 MHz (ERC REC 70-30) bandwidth. The typical application are: Wireless Security Systems, Wireless Sensors and Automatic Meter Reading
Can be mounted for a horizontal or vertical polarization. Here, for a horizontal polarization - an E vector plane is parallel to the ground plane
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.

TetraAnt 868 08 70 - VSWR
Sweep frequency 858 - 878 MHz. Markers: 858 - 868 - 878 MHz
TetraAnt 868 08 70 - Realized Gain
As usual, the antenna's gain was measured with the two-antenna method in a slant arrangement. It takes into account all losses.
