Isolators
In certain conditions, metal objects near the antenna can reduce, isolate, or block the radio signal. In most cases, the operator
should try to avoid any metallic object in the vicinity of the antenna. A metal container or vehicle in the line of sight to the UAV
can block the transmission completely in the worst case. A good way to get out of the inuence of metal parts is the use of an
extendable antenna pole.
Other objects to avoid: Metal railings, heavy metal concrete structures, high voltage pylons, etc. Ask yourself what around you
can conduct electricity. If there is a lot, try changing position.
