Sunnylife Specular Surface Signal Booster for Phantom 3/4 & Inspire 1

The compact and foldable design keeps the booster specular surface protected during transportation. The high quality specular aluminum surface sheet provides a mirror like highly reflective surface that redirects signals back to the antennas. Reflectance: 95%. A thin layer of protective plastic film covers both reflective surfaces, safe-guarding it from smudges, dust or scratches. This peel away film has to be removed before use. Easy, convenient and fast mounting. You can install the Signal booster in no time at all and are ready to go in seconds. Dismounting is also just as fast and easy.
