FAQs

• How do power ratings impact omnidirectional transmit antennas? Selecting an antenna that supports the maximum continuous output power of the transmitter prevents hardware damage. Antennas designed for moderate power transmission inherently function as receiving antennas as well.
• What radiation pattern does a dipole antenna typically exhibit? A standard vertical dipole generates a three-dimensional omnidirectional radiation pattern. This provides continuous horizontal coverage across the azimuth plane while exhibiting signal nulls directly above and below the antenna.
• How do I ensure proper mounting for a fixed-site deployment? Confirm that the supporting mast uses round or square tubing within the specified diameter limits. Always verify structural load capacities and secure all supplied hardware to withstand expected environmental forces.
• 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 did Cyntony's tactical-link field test establish? Cyntony's 2025 XTND-DIRECT field test showed how terrain, antenna height and clearance affected a specific mesh-radio link. The result informs deployment questions; it does not establish range, throughput or suitability for this product (Field-test account).
