Look in the ARRL (American Radio Relay League) Antenna Handbook (or any 
other place) for directions on how to make a "rhombic" antenna.  They 
are high-gain and directional.  At ordinary "high frequency" (3-30 MHz) 
they are too large to be practical.  Guessing that the wireless net is 
in the GHz range, the size should be practical.  A "rhombic" is a 
diamond-shaped antenna and can be made relatively simply.
