The antenna has a maximum transmit power of 1 kW PEP, making it ideal for radio amateurs who want to operate at high powers.\u003c\/p\u003e\n\n\u003cp\u003e \u003cstrong\u003eHow does the Sigma HF-X80XP work?\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003e This antenna is fed with 50 Ohm coaxial cable via a SO-239 connector at the base. The integrated 4:1 UNUN transformer, housed in an IP65 waterproof housing, lowers the impedance at the feed point, resulting in more efficient operation and easy tuning with an external ATU. For users who experience static noise, the antenna can be grounded without affecting tuning.\u003c\/p\u003e\n\n\u003cp\u003e \u003cstrong\u003eFrequency range with external ATU:\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003e 80m (3.5MHz) – 1:1 SWR\u003c\/li\u003e\n\n\u003cli\u003e 60m (5 MHz) – 1:1 SWR\u003c\/li\u003e\n\n\u003cli\u003e 40m (7 MHz) – 1:1 SWR\u003c\/li\u003e\n\n\u003cli\u003e 30m (10 MHz) – 1:1 SWR\u003c\/li\u003e\n\n\u003cli\u003e 20m (14 MHz) – 1:1 SWR\u003c\/li\u003e\n\n\u003cli\u003e 17m (18 MHz) – 1:1 SWR\u003c\/li\u003e\n\n \u003cli\u003e15m (21 MHz) – 1:1 SWR\u003c\/li\u003e\n\n\u003cli\u003e 12m (24 MHz) – 1:1 SWR\u003c\/li\u003e\n\n\u003cli\u003e 10m (28-29 MHz) – 1:1 SWR\u003c\/li\u003e\n\n\u003cli\u003e 6m (50 MHz) – 1:1 SWR\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\u003cp\u003e \u003cstrong\u003eRecommended coaxial cables\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003e Use a high quality 50 Ohm coaxial cable such as RG-213 or Mini-8 for optimal performance.\u003c\/p\u003e\n\n\u003cp\u003e \u003cstrong\u003ePlease note:\u003c\/strong\u003e When using a high power amplifier it is essential to place an external ATU between the antenna and the amplifier to prevent damage.\u003c\/p\u003e\n\n\u003cp\u003e\u003cb\u003e \u003c\/b\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e\n\n\u003cp\u003e\u003c\/p\u003e","brand":"Sigma Euro-Comm","offers":[{"title":"Default Title","offer_id":54983775093118,"sku":"SE HFX80XP","price":169.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0651\/3052\/8953\/files\/Sigma_HF-X80XP.jpg?v=1738417364","url":"https:\/\/www.deltron.nl\/en\/products\/sigma-hf-x80xp","provider":"Deltron","version":"1.0","type":"link"}
