Manufacturer: Coalas systems
Product type: Antennas > Moxon Antenna
COALAS::MOXON-370-440 — a compact and efficient Moxon antenna designed to operate in the 370 MHz–440 MHz range. This model combines moderate directivity, stable electrical characteristics, and ease of installation, making it an excellent option for amateur networks, repeaters, industrial applications, and communication systems on mobile platforms.
Description and Advantages
The antenna has a low standing wave ratio (SWR < 1.5 in the main band), which ensures efficient signal transmission and minimizes losses. The design is lightweight (mass 55 g) and compact (dimensions 284 x 92 mm), allowing the device to be integrated into various structures without significantly affecting weight or aerodynamics. Mounting hardware is included, simplifying installation in both stationary and mobile conditions. With a gain of 5 dBi, the antenna provides a balanced ratio between coverage and beam directivity.

The design includes a 150 mm length of RG316 cable with an SMA Male connector, ensuring broad compatibility with radio frequency equipment. The recommended maximum input power of up to 7 W makes the model suitable for most practical solutions where reliable operation without overheating or signal degradation is required.
The horizontal beamwidth of 84° provides wide coverage for reception and transmission, while the vertical beamwidth of 244° reduces losses when the antenna is tilted. This allows for more flexible antenna placement on carriers with different orientations and ensures stable communication in challenging conditions.
The manufacturer Coalas systems guarantees quality control and compliance of electrical parameters within the specified frequency ranges. Its light weight and compact dimensions make COALAS::MOXON-370-440 a convenient choice for integration into amateur and professional systems where equipment size and mass are important.
