The MaxWiMAX™ is a powerful, state of the art antenna with a gain comparable to that of amplifiers and repeaters. The MaxWiMAX™ attaches to the inside of any glass window via four powerful suction cups and will remove the great majority of EM radiations away from you, yielding up to 22dBi of WiMAX signal gain if pointed towards your provider's tower (mast installation recommended for maximum gain). The MaxWiMAX™ comes with the direct connection specific to your device. It includes 3 feet of thin coaxial cable and also an additional 12-foot FME low-loss coaxial extension. The included device-specific adapter is interchangeable should you change device in the future. The MaxWiMAX™ also comes with a mast mount bracket for external use, in cases where it is necessary to mount the MaxWiMAX™ on a mast to achieve maximum gain.
