The Diamond CPATU is a commercial-grade, high-integrity multiband HF vertical antenna element engineered explicitly for integration with external automatic wire antenna tuners. Spanning a wide frequency threshold from 3.5 to 50MHz, this premium fiberglass radiating mast acts as a highly efficient alternative to complex long-wire setups or space-consuming dipoles. It serves as an essential deployment asset for maritime shore centers, automated tactical base installations, and B2B radiocommunication hardware distribution networks looking to source original factory-certified infrastructure solutions.
The advanced internal architecture of this high-compliance radiating body functions as a tuned wire element designed to match seamlessly with a broad selection of industry-standard auto-tuners, including the Icom AH-4, AH-705, AH-730, Yaesu FC-40, FC-800, and the CG3000 series. Please note that the exact frequency range and max. power rating are depending on the external automatic antenna tuner used. Because of its specialized electronic tuning layout, this product cannot be used with the antenna tuner in the transceiver and manual antenna tuner configurations, as it relies on an intelligent external matching network to safely condition signal paths.
Housed inside a ruggedized, weather-hardened fiberglass structure measuring a total length of 4.6m and registering a balanced structural weight of 2.5kg, the CPATU is built to withstand extreme environmental stress. It features a certified rated wind velocity of 40m/sec., making it stable under heavy coastal storm conditions. Delivered with a heavy-duty mounting bracket array that accepts a wide mast diameter from φ30 to φ62mm, and capable of safely handling a peak power capacity up to 300W SSB, this turnkey element guarantees exceptional field readiness. For comprehensive technical layout diagrams and assembly instructions, please consult the official Installation Manual before deployment.
