VideoLink HA-3752-12-1 Helical Antenna

VideoLink HA-3752-12-1 — a professional broadband helical antenna designed for operation in the 3.7–5.2 GHz range, optimized for 3.8–5.2 GHz. This model combines compact dimensions and low weight, making it convenient for installation on repeaters, point-to-point nodes, wireless links, and mobile platforms, including drones. The antenna is available in configurations with right-hand or left-hand circular polarization (RHCP or LHCP), allowing selection of the appropriate option for specific network tasks.

Description and Advantages

Low weight (50 g) and compact dimensions of 76×76×135 mm simplify installation and minimize load on mounting brackets. Circular polarization reduces the impact of multipath reflections and improves connection stability in motion or with interference. Thanks to its broadband design, the antenna provides reliable communication across a wide frequency spectrum, which is useful for universal solutions in Wi-Fi networks, specialized wireless links, and industrial applications.

The VideoLink HA-3752-12-1 antenna is designed for use in point-to-point communication links, repeaters, access points, and specialized solutions for drones and mobile platforms where compactness and low mass are important. The SMA connector ensures convenient connection to a wide range of radio modules and equipment without the need for complex adapters. The choice of RHCP or LHCP helps reduce losses due to polarization mismatch between transmitter and receiver, and a low standing wave ratio (SWR ≤ 2) guarantees efficient antenna operation in the stated frequency range.

With 14 turns, the helical design provides moderate gain and stable directivity, making antennas of this type an optimal solution for networks with limited mounting space and where reliability is required with minimal structural weight. The VideoLink HA-3752-12-1 combines reliability, versatility, and ease of integration into existing communication systems.

When choosing an antenna, consider polarization compatibility at both ends of the communication link to minimize losses and improve connection quality. This VideoLink model is ideal for deploying modern wireless networks in the 3.7–5.2 GHz frequency range, where compact size, good gain characteristics, and circular polarization are important.
