We're going to show you how to build two antennas - the Downpipe Antenna and the AntCap Antenna.

Now just in case the significance of those names has been lost on you, the Downpipe Antenna is a wide-beam antenna that is suitable for use at the center of a wireless network and is, in fact, made from a length of downpipe.

The AntCap Antenna is, suprisingly enough, made from (you guessed it!) an ant cap. It is a narrow-beam antenna used to connect to either another AntCap (for a point-to-point link), or to a Downpipe antenna.
