425x.09-780-Tx
9 dBd HD omni antenna 695 - 870 MHz, low PIM, null fill
Description
- The 425x 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, and fills the lower pattern nulls.
- 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.
