The Arrowhead operates on 2.3 Ghz, which provides ample separation from standard Wi-Fi frequencies and other potential noise sources. If you are experiencing reduced or deteriorated range is could be caused by the following:

Possible source Causes What to inspect
Environment The main culprit for deteriorated range is environmental factors such as the building you're flying in or the frequency environment you're operating in. First off in troubleshooting, we encourage you to attempt to fly the aircraft in a known environment where you can assess the performance against a known benchmark to rule out any environmental variables.
Antenna Loose antenna connections or unoptimized antenna positions can cause the aircraft to have worse performance. 1. Inspect the SMA on the controller backpack, and make sure the SMA connectors themselves are not loose and cannot spin independently. When mounting the antenna, ensure that the antenna SMA is securely mounted and cannot rotate at all. Rotation in the antenna can be a sign of internal damage.
  1. Also know how to optimize the position of the controller for penetration. The antenna on the Arrowhead controller are circular polarized meaning the deadzone of the antenna points directly up (in the antenna reference frame) (image below). | | Hardware Damage | As stated in the previous section, damage to the modem caused by powering the backpack without the antenna attached can severely degrade the range of the aircraft. | Hardware damage sustained to the radio package must be fixed in our facility to ensure proper repair. |
