• Mounting Interface: Compatible with 20 to 60 mm outer diameter masts

FAQs

• How does a log-periodic dipole array achieve directional coverage? Log-periodic antennas produce directional beams using appropriately sized dipole elements spaced along a central boom. This configuration focuses radiated power in a specific direction while significantly diminishing signals from the rear.
• Why is matching antenna polarization important? An antenna generates an electromagnetic wave oriented in a specific plane. Matching the linear polarization state between transmitting and receiving antennas provides the most efficient transmission path and minimizes signal loss.
• What are the benefits of mounting directional antennas on a telescoping mast? Raising an antenna on a mast improves line-of-sight propagation over obstacles and extends standoff range. This positioning enhances signal reach while allowing associated equipment and personnel to remain concealed.
• Problems we solve: how do we narrow antenna choices? Balancing operating bands, coverage needs and mounting space can make antenna selection difficult. Share those constraints with Cyntony to compare candidate antennas and identify what needs manufacturer confirmation (Our process).
• Outcomes we deliver: what comes from working through the requirements? The practical outcome is a requirements-led set of product options to evaluate with Cyntony. Confirm performance, compatibility and any service scope for your configuration before selection (Our process).
