This 3-section omnidirectional antenna is specifically engineered to operate with automatic antenna tuner systems, covering a frequency range of 1.4 to 30 MHz in transmit and receive (Tx\/Rx).\n\u003c\/p\u003e\n\n\u003ch3\u003eDesign and Performance\u003c\/h3\u003e\n\u003cp\u003e\n    The \u003cstrong\u003eKUM803MWM\u003c\/strong\u003e antenna handles a maximum input power of 1200 Watts PEP (Peak Envelope Power), making it suitable for high-power HF transmitters. Its design incorporates copper radiating elements to prevent galvanic corrosion and a crimp construction that enhances structural robustness. The antenna supports a maximum RF voltage of 18 kV, while the included insulator can withstand a maximum voltage of 100 kV over a length of 210 mm. The characteristic impedance is 50 Ohms, with insulation resistance exceeding 10\u003csup\u003e9\u003c\/sup\u003e Ohms and a static capacitance of 100 pF. The polarization is vertical, and the antenna is not DC-shorted.\n\u003c\/p\u003e\n\n\u003ch3\u003eDurability and Installation\u003c\/h3\u003e\n\u003cp\u003e\n    Constructed from fiberglass with a white polyurethane lacquer finish, this antenna weighs 8 kg. It is designed to withstand harsh marine environmental conditions, with an operating temperature range of -55°C to +60°C and an IP66 protection rating. The \u003cstrong\u003eKUM803MWM\u003c\/strong\u003e can endure winds of 200 km\/h (44 m\/s) and generates a wind load of 293 N at 160 km\/h. The antenna is supplied with an integrated MWM mounting bracket, compatible with masts of 30 to 100 mm diameter using stainless steel hose clamps. Connection is via a side M8x1.25 bolt. The AC Antennas KUM803MWM has been established in the market for over five decades, attesting to its reliability.\n\u003c\/p\u003e","brand":"Ac Antennas","offers":[{"title":"Default Title","offer_id":56090909671764,"sku":"AC-KUM803MWM","price":874.92,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0988\/3274\/4788\/files\/ac-antennas-kum803mwm-antenne-blu-hf-fouet-fibre-3-sections-1200w-longueur-8m-txrx-livre-avec-etrier-1.jpg?v=1781266479","url":"https:\/\/skysat.fr\/en\/products\/ac-antennas-kum803mwm-hf-whip-antenna-fiberglass-8m-1200w","provider":"Skysat","version":"1.0","type":"link"}
