s pe - 13 - 8 - 062/ g /pk page 2 of 13 1 introduction t he gw.26 ht series 2.4 ghz monopole sma (m) ra mount antenna is ideal for 2.4 ghz wireless applications such as wifi, zigbee and bluetooth. antenna housing is made of highly resistant dupont? hytrel? tpee material which is durabl e in high temperature application environments up to 150c. this material is often applied in automotive or industrial applications, where the antenna is placed near the engine or heat generating components. many module manufacturers specify peak gain lim its for any antennas that are to be connected to that module. those peak gain limits are based on free - space conditions. in practice, the peak gain of an antenna tested in free - space can degrade by at least 1 or 2dbi when put inside a device. so ideally yo u should go for a slightly higher peak gain antenna than mentioned on the module specification to compensate for this effect, giving you better performance. upon testing of any of our antennas with your device and a selection of appropriate layout, integr ation technique, or cable, taoglas can make sure any of our antennas peak gain will be below the peak gain limits. taoglas can then issue a specification and/or report for the selected antenna in your device that will clearly show it complying with the pe ak gain limits, so you can be assured you are meeting regulatory requirements for that module. for example, a module manufacturer may state that the antenna must have less than 2dbi peak gain, but you dont need to select an embedded antenna that has a pe ak gain of less than 2dbi in free - space. this will give you a less 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. choosing a taoglas antenna with a higher peak gain than what is specified by the mod ule manufacturer and enlisting our help will ensure you are getting the best performance possible without exceeding the peak gain limits. connection is made via fixed right angle sma(m) connector with a hardened tpee casing, this antenna is the ideal wi - f i - bluetooth - zigbee antenna for m2m devices where the antenna must be placed in harsh high temperature environments .
