VideoLink HA-2944-12-1 Helical Antenna for 2.9-4.4 GHz Band

VideoLink HA-2944-12-1 is a broadband helical circularly polarized antenna from VideoLink, designed to operate in the 2.9-4.4 GHz frequency range. Product category: Antennas > Circular Antennas > Helical Antenna. This model combines compact dimensions and low weight with good antenna characteristics, making it an ideal choice for repeaters, industrial access points, and specialized data transmission systems.

Description and Advantages

The helical design provides circular polarization (both RHCP and LHCP are possible), which increases communication stability in multipath reflections and complex environmental conditions. The antenna is optimized for outdoor mounting, has small dimensions of 76x76x135 mm and a weight of 80 g, simplifying installation on masts, repeater enclosures, and other supports without additional load. The standard SMA connector ensures compatibility with standard feeders and adapters, and broadband characteristics allow the antenna to be used across a wide frequency spectrum.

Technical Specifications

• Frequency Range: 2.9-4.4 GHz
• Gain: from 11 dBi (at 2.9 GHz) to 13 dBi (at 4.4 GHz); nominal gain in documentation — 12.5 dBi
• Beamwidth: from 40° to 50°, typical width ≈45°
• Number of Turns: 14
• Polarization: RHCP or LHCP (circular)
• SWR: not more than 2
• Connector: SMA
• Dimensions: 76x76x135 mm
• Weight: 80 g

These characteristics make the VideoLink HA-2944-12-1 an excellent solution for engineers and installers who require a compact circular antenna with wide coverage and stable polarization. The variable gain across the band allows the system to be adapted to specific terrain conditions and frequency plans, while the choice of right-hand or left-hand circular polarization facilitates setting up the optimal link configuration.

Mounting characteristics: small dimensions and weight simplify installation on various structures, and the standard SMA connector ensures easy integration with existing feeders and adapters. A stable standing wave ratio (not more than 2) ensures efficient energy transfer and compatibility with typical transmitters and receivers.

VideoLink HA-2944-12-1 is suitable for applications in repeaters, industrial wireless communication lines, and specialized data transmission systems where compactness, weight, and polarization stability are important.
