427x.11-780-Tx

11.5 dBd HD omni antenna 740 - 870 MHz, low PIM

Description

The 427x Series colinear antennas are designed for LTE/GSM applications where a durable and high performance antenna is required.
The centre fed dipole design and feed network gives a stable radiation pattern across a wide bandwidth, allows tilted beam designs to be effectively employed without large pattern distortions.
High quality materials and manufacturing techniques are employed to ensure that the antenna has excellent intermodulation performance & wide bandwidth characteristics for multi-channel trunked radio communication systems.
The antenna has been designed to withstand lightning strike. A lightning finial (optional) can be fitted into the top cap via an M10 thread and and earth connection made to the antenna base or clamp.
