VideoLink 4.5–6.3 GHz Helical Antenna

Introducing the VideoLink helical antenna, designed for reliable operation across the wide 4.5–6.3 GHz range. Its compact design and light weight make this antenna an ideal choice for installation on repeaters, access points, and other equipment where limited dimensions and minimal load on mounts are critical. The model offers versatility with selectable RHCP or LHCP circular polarization, enhancing communication channel stability in multipath environments and with various receiver orientations.

The antenna demonstrates uniform gain across the entire operating range: from 11 dBi at 4.5 GHz to 13 dBi at 6.3 GHz, with a typical stated gain of 12.5 dBi. This characteristic allows for stable range and link quality over medium distances, making the device suitable for local repeaters and point-to-multipoint configurations.

Key technical specifications of this helical antenna are presented below:

• Frequency Range: 4.5–6.3 GHz
• Gain: 11 dBi (4.5 GHz) to 13 dBi (6.3 GHz), typically 12.5 dBi
• Polarization: RHCP or LHCP (circular)
• Number of Turns: 14
• Beamwidth: 35–45°
• Radiation Angle: 40–50°
• SWR: not more than 2
• Connector: SMA
• Dimensions: 64×64×110 mm
• Weight: 28 g

Its light weight (28 g) and compact dimensions (64×64×110 mm) simplify mounting on various brackets and facilitate installation on towers or facades. The SMA connector ensures compatibility with a wide range of transmitters and receivers, allowing quick integration of the antenna into existing infrastructure without additional adapters.

The broadband nature of its design and balanced radiation pattern make this antenna suitable for both point-to-point links and the organization of local repeaters where stable operation within 4.5–6.3 GHz is required. An SWR of not more than 2 guarantees an acceptable level of impedance matching with the feeder across the entire operating range, reducing losses and increasing system efficiency.
