• Resonant frequency: 295 MHz
• Input impedance: 50 Ohm
• Max. power: 7 W
• Gain: 5 dBi
• Beamwidth: horizontal — 90°, vertical — 91°
• Connector: RG316 cable (150 mm) + SMA Male
• Dimensions: 380 x 140 mm
• Weight: 80 g
• Mounting hardware included

The COALAS::MOXON-270-330 antenna provides a balanced level of directionality and compactness: a 5 dBi gain combined with a beamwidth of approximately 90° horizontally and 91° vertically allows for stable reception or transmission in a narrow sector without a bulky design. The operating band of 270-330 MHz with a VSWR of less than 1.5 ensures efficient operation across the entire range, and the 295 MHz resonance optimizes throughput in the central part of the band.

The design with a 50 Ohm input impedance allows for easy connection of the antenna to most radio equipment without additional matching devices. The integrated short 150 mm RG316 cable with an SMA Male connector enables quick connection and operation. The maximum permissible power of 7 W makes this model suitable for small transmitters and receivers where high output power is not required.

Dimensions of 380 x 140 mm and a weight of only 80 g make the COALAS::MOXON-270-330 an ideal solution for mounting in confined spaces: the antenna is suitable for installation on masts, small platforms, vehicles, or stationary structures. Mounting hardware is included, allowing for quick antenna attachment and direction adjustment to achieve optimal reception or transmission.

Application Recommendations

• Suitable for amateur and professional use in the 270-330 MHz range.
• Optimal for networks with static or fixed nodes where directionality and moderate gain are required.
• Recommended for use with 50 Ohm equipment to minimize losses and reflected waves.

COALAS::MOXON-270-330 — a practical choice for those seeking an inexpensive, reliable, and easy-to-install Moxon antenna with clearly stated parameters: band 270-330 MHz, resonance 295 MHz, impedance 50 Ohm, max power 7 W, gain 5 dBi, beamwidth horiz. 90° / vert. 91°, connector RG316 (150 mm) + SMA Male, dimensions 380 x 140 mm, weight 80 g, mounting hardware included.
