{"product_id":"schwarzbeck-efs-9221","title":"Schwarzbeck EFS 9221","description":"\u003ch1 class=\"h3\"\u003eSchwarzbeck EFS 9221\u003c\/h1\u003e\n\u003cdiv class=\"p\"\u003e\u003cp\u003eThe EFS 9221 is an active, symmetrical biconical antenna with a wide frequency range of more than 5 decades and a remarkable flat frequency response. In contrast to the frequently used unsymmetrical vertical monopole or rod antennas the EFS 9221 allows precise fieldstrength measurements, thanks to a very high common mode rejection. Because of its small dimensions and a built in rechargeable NiMH battery the EFS 9221 is a perfect choice for portable applications. The sensitivity can be improved by approx. 11 dB using the optional BBUK 9139 M4 biconical elements. Frequency range: 9 kHz – 1 GHz.\u003c\/p\u003e\u003c\/div\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/www.schwarzbeck.com\/antennas\/active-antennas\/efs-9221\/\" rel=\"noopener\" target=\"_blank\"\u003eOfficial product page\u003c\/a\u003e\u003c\/p\u003e\n","brand":"Schwarzbeck","offers":[{"title":"Default Title","offer_id":53926739411238,"sku":null,"price":0.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0953\/9797\/0214\/files\/EFS-9221-1_3f8920d3-c119-4cb9-91e2-68146444dd01.jpg?v=1789979077","url":"https:\/\/nplab.shop\/products\/schwarzbeck-efs-9221","provider":"NP LAB","version":"1.0","type":"link"}
