Never mix and match an external A1 - A4 stiff antenna with an A5 - A8 (550 - 638 MHz) or B1 - B4 (630 - 718 MHz) transmitter bodypack. Mismatching the antenna block creates an impedance imbalance that reduces your transmission distance and risks damaging the internal output stage over long sessions.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003cblockquote data-path-to-node=\"15\"\u003e\n\u003cp data-path-to-node=\"15,0\"\u003e\u003cb data-path-to-node=\"15,0\" data-index-in-node=\"0\"\u003eTool-Free Replacement Best Practices:\u003c\/b\u003e Threading or unthreading the antenna should always be handled entirely by hand. Grip the reinforced metal collar at the base of the antenna and turn it smoothly clockwise until it is snug against the SK 6212 body. Do not overtighten or use pliers, as stripping the miniature threads can compromise the moisture-resistant seal. Ensure the contact pin is completely dry and free of skin oil before screwing it into place.\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003c\/div\u003e","brand":"Sennheiser","offers":[{"title":"Default Title","offer_id":52073378382126,"sku":"SEN-508888","price":1069.5,"currency_code":"ZAR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/0157\/2910\/files\/SEN-508888_image1.jpg?v=1782390830","url":"https:\/\/shopvisuals.tv\/products\/sennheiser-sk-6212-stiff-antenna-a1-a4","provider":"ShopVisuals.tv","version":"1.0","type":"link"}
