Both deliver 2.5 dBi gain with similar VSWR performance (1.17 vs 1.15). The JW-3 is a straight (non-bendable) design, while the JK-11 supports bending.

Confirm your device has an SMA-K (standard SMA female) port before ordering. 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 antenna orientation affect performance?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: Yes. As a vertically polarized omnidirectional antenna, the TX2400-JW-3 radiates most effectively in the horizontal plane perpendicular to the antenna rod. Mounting the antenna vertically maximizes horizontal coverage. Avoid pointing the antenna tip directly at the receiving station, as the radiation pattern has a null at the tip (along the antenna axis). For devices mounted flat on a surface, consider an antenna with a right-angle connector to maintain vertical orientation.\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 the 29mm height limit gain compared to longer antennas?\u003c\/p\u003e\n\n\u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: Yes. At 2.4GHz, a quarter-wave radiator measures approximately 31mm. The TX2400-JW-3's 29mm radiator is close to quarter-wave length, achieving 2.5 dBi gain — comparable to a standard quarter-wave antenna. Longer antennas such as the TX2400-JKD-20 (200mm, 5.0 dBi) achieve higher gain by using a 5\/8-wave equivalent design, but require significantly more height clearance. The JW-3 represents the practical minimum size for a 2.5 dBi SMA-J antenna at 2.4GHz.\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-JW-3 is rated for -40°C to +85°C. The TPEE radome is weather-resistant and UV-stable, suitable for protected outdoor installations. For direct rain exposure, protect the SMA connector junction with self-amalgamating tape to prevent moisture ingress. The 2g weight minimizes wind-induced vibration stress on the SMA connector in outdoor deployments.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n","brand":"cdsenet","offers":[{"title":"Default Title","offer_id":45301875900518,"sku":"TX2400-JW-3","price":0.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/9918\/9350\/files\/TX2400-JW-3-_1_800x800_v2.jpg?v=1773986454","url":"https:\/\/cdsenet.store\/products\/tx2400-jw-3-2-4ghz-wifi-mini-rubber-antenna-2-5dbi-sma-j","provider":"CDSENET, Built for the Wireless World","version":"1.0","type":"link"}
