Currently I am using a a wireless router (Asus RT-N12) and Wireless USB adaptor (TL-WN722N). Both of these have removable external antennas (RP-SMA connectors).

I want to know the correct and safe way to change an antenna on a wireless device.

Should I power of the device first? Will changing an antenna while the device is running damage the antenna and/or hardware?

I'm quite new to wireless technology and have minimal background with electronics. I did a quick search on the web but didn't find any answers to my question.

There is no need to turn off the equipment. You can safely change the antenna when router is turned on.

According to http://en.wikipedia.org/wiki/DBm the maximum power of wi-fi is only 200mW, so its too low to short-circuit something.

To attach the ANT24-0700C antenna, remove the default detachable antenna from the wireless access point or router, and connect the ANT24-0700C antenna to the RP-SMA receptacle of the wireless device
