The ZX-30-3 is a 30m monobander designed by ON4UN, featuring three elements with a power rating of 3kW. Known for its forward gain of 9.1dB and a VSWR of 1.2:1 (typical), this antenna boasts a boom length of 8.55m. Due to critical element spacing, single-band antennas like the ZX-30-3 offer advantages such as optimized F/B ratio and forward gain. With gamma matching, a simple, reliable, and lossless method, achieving the perfect feed impedance match becomes effortless without introducing losses from traps commonly found in multi-band antennas.

The ZX Mono Band Yagis by ON4UN are renowned for their purity as single-band antennas. By focusing on a specific band, designers can optimize the antenna for maximum gain and front-to-back ratio performance. The gamma matching technique, favoured by many antenna designers worldwide, ensures a seamless and efficient impedance match for enhanced antenna performance. Unlike multi-band antennas, the monoband design eliminates the need for compromises, allowing for superior gain and F/B ratio on the designated band without the drawbacks of trap-induced losses.

For those interested in the ZX-30-3 3-element 30m Mono Band Beam, it is essential to note that additional carriage costs may apply.
