The Taoglas TG.66 is a hinged monopole antenna designed to cover all global 5G/4G frequencies between 600 MHz and 6GHz. Despite its miniature size, just 70.3 x 10 mm, the TG.66 has omnidirectional radiation patterns and provides stable gain across the hemisphere. The TG.66 has a rotatable, hinged 90° SMA connector, allowing covert installation on all types of gateways and routers at straight or bent angles. The TG.66 performs excellently at 5G bands with efficiencies above 45% across the entire 5G/4G spectrum when positioned on the edge of a small ground plane of just 120 x 45 mm in size. The TG.66 utilizes a sleek, robust PC enclosure, and its small size allows it to be mounted where space is at a premium. The SMA male hinge mechanism allows full rotation, helping avoid other antennas or objects and with isolation by pointing the antennas in different directions when used in MIMO systems or when other antennas are present on the same device. The TG.66 has been evolved from the highly successful TG.09 and is part of the ever-growing portfolio of 5G antennas offered by Taoglas.
