Omni Antennas428x.11-780-Tx

11 dBd HD omni antenna 740 - 870 MHz, low PIM, null fill

Description

  • The 428x 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.
