This includes popular LoRa modules (E32-170T30D, SX1278-based transceivers), VHF data radios, and industrial telemetry systems. The antenna's 50¦¸ impedance ensures proper matching with standard RF transceivers.

The TPEE (thermoplastic elastomer) material provides excellent weather resistance, UV stability, and chemical resistance across an operating temperature range of -40¡ãC to +85¡ãC. The antenna is RoHS compliant and, when the SMA connector is properly sealed (using heat-shrink tubing or silicone sealant), achieves IP67-level protection against dust and temporary water immersion. The flexible design withstands over 5,000 bend cycles, making it suitable for mobile applications and vibration-prone industrial installations.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 20px; padding: 15px; background: #f9f9f9; border-left: 4px solid #0056b3; border-radius: 4px;\"\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 8px; color: #111;\"\u003eQ: What is the maximum power this antenna can handle?\u003c\/p\u003e\n\u003cp style=\"color: #666; margin: 0; font-size: 14px; line-height: 1.6;\"\u003eA: The TX170-JK-11 is rated for a maximum input power of 10W (40 dBm). This power capacity is suitable for most industrial VHF applications, including high-power LoRa modules and industrial telemetry systems. Exceeding this power rating may cause thermal damage to the TPEE radome or connector degradation. For typical IoT applications using 100mW-1W transmitters, this antenna provides a substantial safety margin. Always ensure your transmitter output power does not exceed 10W to maintain antenna longevity and performance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"margin-bottom: 20px; padding: 15px; background: #f9f9f9; border-left: 4px solid #0056b3; border-radius: 4px;\"\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 8px; color: #111;\"\u003eQ: How do I properly install and optimize this antenna?\u003c\/p\u003e\n\u003cp style=\"color: #666; margin: 0; font-size: 14px; line-height: 1.6;\"\u003eA: For optimal performance, mount the antenna vertically (perpendicular to the ground plane) with the flexible joint allowing 90-degree adjustment for fine-tuning signal direction. Avoid mounting near large metal surfaces or inside fully enclosed metal enclosures, as this will detune the antenna and increase VSWR. The flexible design allows installation in compact spaces where rigid antennas cannot fit. Tighten the SMA connector to 5-8 in-lbs torque using a torque wrench to ensure proper electrical contact and mechanical stability. After installation, verify VSWR using a network analyzer or SWR meter to confirm VSWR remains below 2.0 across your operating frequency.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"padding: 15px; background: #f9f9f9; border-left: 4px solid #0056b3; border-radius: 4px;\"\u003e\n\u003cp style=\"font-weight: bold; margin-bottom: 8px; color: #111;\"\u003eQ: What is the expected communication range with this antenna?\u003c\/p\u003e\n\u003cp style=\"color: #666; margin: 0; font-size: 14px; line-height: 1.6;\"\u003eA: Communication range depends on transmitter power, receiver sensitivity, terrain, and environmental factors. With a typical 100mW (20dBm) VHF transmitter and -110dBm receiver sensitivity, expect line-of-sight range of 1-2.5 km in open areas. The 2.5 dBi gain provides approximately 1.8x range improvement compared to a 0 dBi reference antenna. VHF frequencies (148-173 MHz) offer superior building penetration and longer range compared to UHF or 2.4GHz alternatives, making this antenna ideal for urban and industrial environments with obstacles. For extended range, consider higher transmit power (within regulatory limits) or deploying repeaters.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"cdsenet","offers":[{"title":"Default Title","offer_id":45195786322022,"sku":"tx170-jk-11","price":1.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/9918\/9350\/files\/TX170-JK-11-_2_800x800_v2.jpg?v=1773459559","url":"https:\/\/cdsenet.store\/products\/tx170-jk-11","provider":"CDSENET, Built for the Wireless World","version":"1.0","type":"link"}
