margin: 0; font-size: 14px;\"\u003eA: The TX2400-JKD-20 is compatible with any 2.4GHz device featuring an SMA-K (female) port, including WiFi routers, access points, smart home gateways, and wireless modules. Confirm your device has an SMA-K (female) port before ordering. SMA and RP-SMA connectors are not interchangeable — RP-SMA reverses the pin\/socket arrangement and is commonly found on consumer WiFi routers. Check your router's antenna port type before purchasing.\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: How does 5.0 dBi gain compare to standard router antennas?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: Most consumer WiFi router stock antennas are rated at 2.0–3.0 dBi. The TX2400-JKD-20's 5.0 dBi gain provides approximately 2–3 dB more gain, which translates to roughly 58–100% more effective radiated power in the horizontal plane. This is achieved by compressing the radiation pattern toward the horizon (reducing energy radiated upward\/downward), which is beneficial for single-floor deployments but less effective for multi-story coverage.\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 antenna affect its 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 the antenna alters the radiation pattern — a bent antenna no longer radiates in a purely omnidirectional pattern. For applications requiring consistent omnidirectional coverage, mount the antenna vertically. Use the bend capability for space-constrained installations or to redirect the radiation pattern toward a specific area.\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: What factors affect WiFi communication distance with this antenna?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: Key factors include: (1) physical barriers — concrete walls attenuate 2.4GHz signals by 10–15 dB per wall; (2) antenna orientation — the 5.0 dBi gain is concentrated in the horizontal plane, so vertical mounting maximizes horizontal coverage; (3) proximity to metal surfaces — metal objects within 50mm of the antenna can detune the radiator and increase VSWR; (4) interference from other 2.4GHz devices on the same channel.\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 the TPEE radome suitable for outdoor use?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: The TX2400-JKD-20 is rated for -40°C to +85°C. The TPEE radome is weather-resistant and suitable for protected outdoor installations. For direct rain or high-humidity exposure, protect the SMA connector junction with self-amalgamating tape to prevent moisture ingress. The TPEE material provides better crack resistance than standard rubber compounds under repeated flexing and temperature cycling.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n","brand":"cdsenet","offers":[{"title":"Default Title","offer_id":45301875834982,"sku":"TX2400-JKD-20","price":1.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/9918\/9350\/files\/TX2400-JKD-20-_1_800x800_v2.jpg?v=1773986454","url":"https:\/\/cdsenet.store\/products\/tx2400-jkd-20-2-4ghz-wifi-antenna-5-0dbi-sma-j-tpee","provider":"CDSENET, Built for the Wireless World","version":"1.0","type":"link"}
