23cm High Gain Omni Stack Antenna 23cm4omni Four Dipoles

23cm High Gain Omni Stack Antenna 23cm4omni consists of four dipoles with an integrated internal 4-Way divider and one “N” output connector. The antenna is intended for 23cm repeaters or similar purposes.

 

Key Features:

• High Gain: Provides a free-space forward gain of 8.2 dBi.
• Omnidirectional radiation pattern.
• Wideband characteristics in any 20MHz BW range: Say 1272 – 1292 MHz.
• Maximum power up to 400W.
• Excellent return loss (“RL”) over the whole range, about -18 dB or more.
• Integrated 4-way internal divider.
• No tuning. All is pre-tuned.
• “N” Output connector.

Antennas-Amplifiers Product Benefits. A Major advance in antenna design.

• F/B and G/T superiority.
  All antennas have been calculated using state-of-the-art full 3D EM modeling software, including the influence of the boom, bracket, baluns, and connectors. The performance of antennas designed using these techniques is exceptional, significantly outperforming those designed with the EZNEC program.
• No tuning antennas.
  Before dispatch, we assemble and test each antenna’s characteristics. No need to tune any element to get a perfect SWR on the intended frequency range. Everything is pre-tuned.
• Easy to set up.
  Everything is labeled; just put a number to a number. Everything is included in the box: Antenna, balun, bracket, and guy rope support if needed. Yours is to assemble and have fun!
• Mechanical properties.
  We believe that our antennas are the world’s strongest antennas and are mechanically constructed much better than any antennas from other manufacturers.
