The TX2400-JK-11 delivers 2.5 dBi with a compact form factor and VSWR of 1.15 at 2.4GHz — optimized for direct-mount on IoT modules and compact devices. The TX2400-JKD-20 delivers 5.0 dBi with a 200mm radiator for extended range on routers and APs.

RP-SMA reverses the pin\/socket arrangement — the router port has an inner pin, while SMA-J also has an inner pin, making them mechanically similar but electrically incompatible. For RP-SMA router ports, use an RP-SMA male antenna or an SMA-to-RP-SMA adapter.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"margin-bottom: 20px; padding: 15px; background: #fafafa; border-radius: 8px;\"\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 6px;\"\u003eQ: Does bending the TPEE antenna affect RF performance?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: Yes. The VSWR specification of ≤1.5 is measured with the antenna in a straight vertical position. Bending alters the radiation pattern — a bent antenna no longer radiates in a purely omnidirectional pattern. The TPEE material allows bending without mechanical damage, but for applications requiring consistent omnidirectional coverage, mount the antenna vertically. Use the bend capability only for space-constrained installations where pattern symmetry is less critical.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv style=\"padding: 15px; background: #fafafa; border-radius: 8px;\"\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 6px;\"\u003eQ: What is the operating temperature range and is it suitable for outdoor use?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: The TX2400-JK-11 is rated for -40°C to +85°C. The TPEE radome is UV-stable and weather-resistant, suitable for protected outdoor installations such as industrial cabinets and outdoor IoT enclosures. For direct rain exposure, protect the SMA connector junction with self-amalgamating tape. TPEE provides better crack resistance than standard rubber under repeated temperature cycling and UV exposure.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n","brand":"cdsenet","offers":[{"title":"Default Title","offer_id":45301875802214,"sku":"TX2400-JK-11","price":0.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/9918\/9350\/files\/TX2400-JK-11-_2_800x800_v2.jpg?v=1773986454","url":"https:\/\/cdsenet.store\/products\/tx2400-jk-11-2-4ghz-wifi-bluetooth-antenna-2-5dbi-sma-j","provider":"CDSENET, Built for the Wireless World","version":"1.0","type":"link"}
