Covering the broad \u003cstrong\u003e410–510 MHz\u003c\/strong\u003e spectrum in a single unit, it eliminates the need for separate 433 MHz and 470 MHz antennas — a key advantage over single-band alternatives. At \u003cstrong\u003e600 mm physical length\u003c\/strong\u003e, it is significantly more compact than 12 dBi high-gain variants (typically 1200 mm+), while still delivering a measured \u003cstrong\u003e6.0 dBi peak gain\u003c\/strong\u003e with \u003cstrong\u003eVSWR ≤ 1.5\u003c\/strong\u003e across the full band. Weighing only \u003cstrong\u003e183 g\u003c\/strong\u003e, it imposes minimal wind-load on pole and rooftop mounts. The sub-GHz wavelength (~69 cm at 433 MHz) provides inherently superior wall and foliage penetration compared to 2.4 GHz antennas, making this the preferred choice for outdoor LoRa gateways, smart metering base stations, and industrial telemetry nodes in obstructed environments.

To bridge the two, use a low-loss \"N Female to SMA Male\" RF pigtail cable rated for sub-GHz frequencies.

The TX400-BLG-55's 100 MHz bandwidth (410–510 MHz) covers both allocations in a single antenna, making it suitable for multi-region gateway deployments without hardware changes. This eliminates the need to stock separate 433 MHz and 470 MHz antennas for different markets.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 5px;\"\u003eQ: Does the 600 mm length and 183 g weight create structural risk on rooftop or pole mounts during high-wind conditions?\u003c\/p\u003e\n\n\u003cp style=\"color: #666; margin: 0; font-size: 14px;\"\u003eA: The 183 g mass is specifically engineered to minimize wind-load torque on mounting hardware. At sub-GHz frequencies, achieving 6.0 dBi gain requires a physically longer radiating element than at 2.4 GHz — the 600 mm length is the minimum necessary for this gain level. The FRP radome provides structural rigidity without adding significant weight, and the antenna's slim profile reduces aerodynamic drag. For permanent rooftop installations in high-wind zones, use a heavy-duty pole clamp rated for the mast diameter and verify the mount's wind-load specification against local building codes.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n","brand":"cdsenet","offers":[{"title":"Default Title","offer_id":45314746744934,"sku":"TX400-BLG-55","price":40.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/9918\/9350\/files\/TX400-BLG-55-_1_800x800_v2.jpg?v=1773986648","url":"https:\/\/cdsenet.store\/products\/tx400-blg-55","provider":"CDSENET, Built for the Wireless World","version":"1.0","type":"link"}
