The TX230-XP-200 uses an ABS+PC enclosed housing (impact-resistant, UV-stable) with a 200cm cable. The TX230-TB-300 uses a bare pure copper rod radiator with a larger magnetic base and a 300cm RG58 cable. Choose XP-200 for ruggedized enclosed housing and vehicle\/industrial deployments; choose TB-300 for maximum cable reach (300cm) and open-air installations where the bare copper rod is not a concern.\u003c\/p\u003e\n    \u003c\/div\u003e\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 TX230-XP-200 require a metal ground plane?\u003c\/p\u003e\n      \u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: Yes. The magnetic sucker base must be mounted on a ferromagnetic metal surface (steel or iron) to adhere and to function as a ground plane. A larger metal surface improves radiation efficiency — a minimum of 150 × 150mm is recommended, with 200 × 200mm or larger preferred. Mounting on plastic, wood, or fiberglass will prevent the base from holding and will degrade gain by 2–3 dBi. For non-metallic surfaces, place a steel sheet under the base.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"margin-bottom: 20px; padding: 15px; background: #fafafa; border-radius: 8px;\"\u003e\n      \u003cp style=\"font-weight: bold; margin-bottom: 6px;\"\u003eQ: Is this compatible with 433MHz or other sub-1GHz modules?\u003c\/p\u003e\n      \u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: No. The TX230-XP-200 is tuned for 225–237.6MHz. Using it at 433MHz will result in a VSWR exceeding 5.0 and a communication range reduction of 80% or more. For 433MHz LoRa or FSK applications, use a dedicated 433MHz antenna. For 170MHz applications, use the TX170-XP-200.

This is significantly higher than the 10W limit of direct-mount rubber antennas such as the TX230-JK-11. Ensure the cable and connector are rated for the transmitter's output power before use.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \u003cdiv style=\"padding: 15px; background: #fafafa; border-radius: 8px;\"\u003e\n      \u003cp style=\"font-weight: bold; margin-bottom: 6px;\"\u003eQ: Is the ABS+PC housing suitable for outdoor use?\u003c\/p\u003e\n      \u003cp style=\"color: #555; margin: 0; font-size: 14px;\"\u003eA: Yes. The ABS+PC housing is UV-stable and impact-resistant, rated for -40°C to +85°C, making it suitable for outdoor industrial deployments. For direct rain exposure, protect the SMA connector junction with self-amalgamating tape or a weatherproof boot to prevent moisture ingress at the connector interface. The enclosed housing provides mechanical protection that bare copper rod antennas do not offer in high-traffic or exposed environments.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/section\u003e\n\n\u003c\/div\u003e","brand":"cdsenet","offers":[{"title":"Default Title","offer_id":45301875638374,"sku":"tx230-xp-200","price":3.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0702\/9918\/9350\/files\/TX230-XP-200-_2_800x800_v2.jpg?v=1773986648","url":"https:\/\/cdsenet.store\/products\/tx230-xp-200-230mhz-vhf-magnetic-antenna-4-0dbi-sma-j","provider":"CDSENET, Built for the Wireless World","version":"1.0","type":"link"}
