Always try your best to keep your amtenna right by your LoRa device. This gives you best range. 

To reduce signal loss traveling through the coaxial cable (if your antenna is far away from the device) use a LMR-240 or for even lower signal loss you can go to a LMR-400 coax cable. 

Select your length & you can get LMR-400 on amazon if needed 👇
