You will need to buy a signal amplifier antenna. One that doe not have to be connected to the radio. It will provide the amplified signal and the radio antenna (the a/c line cord and the back of the clock/radio) will be able to pick up the signal from the amplified antenna.[http://www.radiolabs.com/products/antennas/am-antenna.php] this web link will show you one type of these antenna's. Copy the web link and paste it into the address bar in your browser. It will take you to the website. There maybe other types of these antenna's but this one had the best price.

You need a 5.8ghz antenna. 5.8 ghz is about twice the frequency of 2.4 ghz, and conversely half the wave length.
Thus for a similar physical size antenna, you can have to twice the number of elements in a 5.8 ghz antenna, giving you a 3 dB improvement.
But 16 dBi is 5 dB more than 11 dBi, so what gives? Well, it's the particular electrical design that can have a difference.
