Its square halo form factor measures just 600mm across, making it one of the most space-efficient options for 4m operation — well suited to loft installations, portable setups, or any location where a full-size dipole isn’t practical.\u003c\/p\u003e\u003cp\u003eOmni-directional coverage with unity gain ensures consistent horizontal radiation in all directions, while the direct dipole centre connection keeps the feed arrangement clean and straightforward. VSWR of 1.5:1 or better and a 200W power rating make it a reliable choice for SSB and FM operation on the 4m band.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eHalo loop folded dipole design — compact and omni-directional\u003c\/li\u003e\n\u003cli\u003eFrequency: 70–71 MHz (4m amateur band)\u003c\/li\u003e\n\u003cli\u003eUnity gain — consistent coverage in all horizontal directions\u003c\/li\u003e\n\u003cli\u003eLow VSWR: 1.5:1 or better\u003c\/li\u003e\n\u003cli\u003e200W power rating\u003c\/li\u003e\n\u003cli\u003eOverall square size: 600mm — smaller footprint than the 6m HLP-6\u003c\/li\u003e\n\u003cli\u003eDirect connection to dipole centre — simple feed arrangement\u003c\/li\u003e\n\u003cli\u003eSuitable for portable, loft, or fixed base station use\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: Folded dipole (halo loop)\u003c\/li\u003e\n\u003cli\u003eFrequency: 70–71 MHz\u003c\/li\u003e\n\u003cli\u003eVSWR: 1.5:1 or better\u003c\/li\u003e\n\u003cli\u003ePower: 200W\u003c\/li\u003e\n\u003cli\u003eOverall size: 600mm square\u003c\/li\u003e\n\u003cli\u003eConnection: Direct to dipole centre\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Moonraker","offers":[{"title":"Default Title","offer_id":57528366006616,"sku":"MOON-11-097","price":44.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0819\/8753\/5192\/files\/11-097-1.jpg?v=1781697739","url":"https:\/\/kamsat.co.uk\/products\/hlp-4-70mhz-4m-halo-loop-folded-dipole-antenna","provider":"Kamsat","version":"1.0","type":"link"}
