Thanks to Manuel aka Tysonpower for submitting to us his extremely cheap ADS-B antenna build. 9-6GHz support MiMo/Diversity operation for WiFi and WiMAX and optional high-performance GPS/GNSS antenna with an integrated 26dB gain LNA and high-quality. Mount GPS antenna as far as possible from other RF devices: The D4R-ii RC Receiver is known to interfere with GPS. The length of the radialls are somewhat critical for ground plane antennas. Specifications. Attempt to space at least 16 inches from an adjacent antenna or metallic structure and choose a location with gentle surface curves to ensure proper sealing. the ground plane as well as the matching of the an tenna to fits. Multi-constellation receivers such as GPS/GLONASS require antennas with an operational bandwidth of up to 32 MHz, and up to 49 MHz to also cover Compass. ADVANCED AIRCRAFT ELECTRONICS HIGH GAIN ANTENNA VHF-5 Here is a new series of aircraft antennas specifically designed to be used without a ground plane. The LP[G]M[T]M[B]-7-27-[24-58] consists of up to 7 elements; two isolated high-performance antenna elements covering 698-2700MHz offer MiMo/Diversity at cellular/LTE frequencies, up to 4 optional dual band elements covering 2. The antenna has RHCP characteristics suitable for reception of GPS signals.
