Standing at an impressive \u003cstrong\u003e1200mm physical length\u003c\/strong\u003e, it accommodates an extended multi-dipole internal array to achieve a verified \u003cstrong\u003e8.0 dBi peak gain\u003c\/strong\u003e. Unlike shorter unity-gain antennas, this 1.2-meter structure compresses the vertical beamwidth, directing a massive amount of RF energy toward the horizon.

Because the TX433-BLG-120 is a heavy-duty 391g outdoor antenna featuring an industrial N-J connector, you must use a high-quality \"N Female to SMA Male\" RF adapter cable to bridge the hardware.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 20px;\"\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 5px;\"\u003eQ: How does the 433MHz frequency combined with 8.0 dBi gain improve signal penetration compared to standard 2.4GHz antennas?\u003c\/p\u003e\n\u003cp style=\"color: #666; margin: 0; font-size: 14px;\"\u003eA: It is a combination of physics and beam shaping. The 433MHz frequency has a much longer wavelength than 2.4GHz, allowing the wave to naturally \"bend\" (diffract) around solid walls and trees rather than scattering. Simultaneously, the 8.0 dBi gain (achieved via the 1200mm tube length) forcefully focuses that penetrating wave horizontally. This combo ensures the signal punches through physical barriers without losing its forward momentum.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 5px;\"\u003eQ: Does the 1200mm length and 391g weight require special outdoor mounting considerations?\u003c\/p\u003e\n\u003cp style=\"color: #666; margin: 0; font-size: 14px;\"\u003eA: Yes. At 1.2 meters tall and weighing 391g, this antenna generates a moderate wind load. You must use sturdy, galvanized steel U-bolt brackets to secure the antenna mast to a pole or wall. Furthermore, to protect your RF system, always seal the N-J connector joint at the base with professional waterproof amalgamating tape to prevent rainwater ingress from ruining the VSWR performance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"cdsenet","offers":[{"title":"tx433-blg-175","offer_id":45512020852838,"sku":"tx433-blg-175","price":92.77,"currency_code":"USD","in_stock":true},{"title":"tx433-blg-120","offer_id":45512020885606,"sku":"tx433-blg-120","price":49.3,"currency_code":"USD","in_stock":true},{"title":"tx433-blg-90p","offer_id":45512020918374,"sku":"tx433-blg-90p","price":144.95,"currency_code":"USD","in_stock":true},{"title":"tx433-blg-48","offer_id":45512020951142,"sku":"tx433-blg-48","price":31.9,"currency_code":"USD","in_stock":true},{"title":"tx433-blg-40","offer_id":45512020983910,"sku":"tx433-blg-40","price":22.34,"currency_code":"USD","in_stock":true},{"title":"tx433-blg-20L","offer_id":45512021016678,"sku":"tx433-blg-20L","price":20.31,"currency_code":"USD","in_stock":true},{"title":"tx433-blg-20","offer_id":45512043036774,"sku":"TX433-BLG-20","price":17.41,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/9918\/9350\/files\/TX433-BLG-120-_2_800x800_v2.jpg?v=1776073600","url":"https:\/\/cdsenet.store\/products\/tx433-blg-120","provider":"CDSENET, Built for the Wireless World","version":"1.0","type":"link"}
