High-Gain Dual-Band Antenna Pack The Dray Tek ANT-1205 is a replacement aerial (antenna) for any Dray Tek router or wireless access point. It provides up to a 5d Bi gain (vs. the 2 or 3 dBi standard aerial supplied with the product). The ANT-1205 can increase coverage in your environment, creating a stronger signal for your Wi Fi coverage. A high-gain aerial achieves this by creating a narrower and therefore more concentrated radiation pattern. It is still an omnidirectional aerial, i. e. signal radiates in all directions (360 degrees) perpendicular to the aerial\'s length. The ANT-1205 is supplied as a pair of antennas, ideal for most Dray Tek wireless access points and wireless routers. The ANT-1205 is a dual band aerial so can be used for either 2. 4Ghz or 5. 8Ghz operation, or both simultaneously. It is also suitable for 802. 11ac operation (5. 8Ghz). The aerial can tilt at its base to allow for optimum coverage/spread, or to allow for router wall mounting. Instead of mounting the aerials on the back of your router directly, you can use an optional magnetic base (Part Code: ANT-BAS1) - useful if your router is in a rack or to get the best aerial position. The optional base can be wall mounted using suitable adhesive pads (e. g. 3M Command Strips).
