An 8dBi patch can easily double range when compared with a ~2dBi dipole.  

 

Link Margin Definition:  

In a wireless communication system, the link margin, measured in dB, is the difference between the 

receiver's sensitivity (i.e., the received power at which the receiver will stop working) and the actual received 

power. A 15 dB link margin means that the system could tolerate an additional 15 dB of attenuation 

between the transmitter and the receiver, and it would still just barely work.
