This is good for touring the outback, heading up the Hume or playing i-spy with your mates on the treeless Nullarbor desert plains. The signal radiates in a straight narrow path.\u003c\/li\u003e\n\u003cli\u003eMedium Gain Antenna (5.1 - 6.6 dBi) - This is the go to antenna if you do a bit of everything. This antenna is ideally suited to those who drive around suburban and country areas. The medium gain antennas are less likely to be obstructed from buildings, trees or mountains. \u003c\/li\u003e\n\u003cli\u003eUnity gain (2.1 dBi) - This describes an antenna that outputs a signal the same level as the input. It works on a very broad pattern and is  far less likely to be obstructed from buildings, trees, rugged terrain or mountains.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eGME are the leading name in radio communication  and continue to manufacture their innovative products in Australia.
