SPECIFICATION Part No. : GW.17.07.0250E Product Name : 2.
1. Introduction The GW.17 Click–in Terminal Antenna is a high performance robust 2.4GHz dipole antenna designed for quick assembly onto finished products. The specially designed click in plastic head greatly reduces the assembly time and cost compared with most terminal antennas with connector. The standard product comes with 250mm low loss RG-178 cable and IPEX MHFI (U.FL) connector.
optimized solution. It is better to go for a slightly higher free-space peak gain of 3dBi or more if available. Once that antenna gets integrated into your device, performance will degrade below this 2dBi peak gain due to the effects of GND plane, surrounding components, and device housing. If you want to be absolutely sure, contact Taoglas and we will test.

5. Ground Plane Effect Three ground setups are used to see the affect of positioning GW.17close to ground 1. Small Ground (15 x 9cm) – common size of CPE devices. GW.17 is mounted at the longer edge for testing. 2. Big Ground Edge (45 x 30cm) – simulate the effect of mounting antenna on a base station device. GW.17 is mounted at the centre of the longer edge. 3. Big Ground Centre (45 x 30cm) – simulate the effect of mounting antenna in a centre of a big ground plane, such as vehicle top.
