Most LoRa concentrator HATs for the Raspberry Pi (such as those based on the SX1302) have a matching U.FL socket on the board. You simply press the IPEX connector onto the socket until it clicks, allowing you to mount the actual antenna rod further away.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails class=\"faq-item\"\u003e\n\u003csummary\u003e3. What is the difference between this rubber rod antenna and a fiberglass antenna?\u003c\/summary\u003e\n\u003cp\u003eRubber rod antennas are designed for indoor or protected outdoor use on small devices (gateways, sensors). They are lightweight and low-gain (2-3dBi), providing a wide, spherical signal. Fiberglass antennas (like our BLG series) are heavy-duty, high-gain (up to 12dBi), and fully waterproof for permanent outdoor mast mounting to achieve long-distance links.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"cdsenet","offers":[{"title":"tx915-jz-5","offer_id":45516816056422,"sku":"tx915-jz-5","price":0.95,"currency_code":"USD","in_stock":true},{"title":"tx915-jzlw-15","offer_id":45516816089190,"sku":"tx915-jzlw-15","price":1.6,"currency_code":"USD","in_stock":true}],"url":"https:\/\/cdsenet.store\/products\/tx915-jz-series-915mhz-rubber-rod-lora-antenna-sma-ipex","provider":"CDSENET, Built for the Wireless World","version":"1.0","type":"link"}
