Below chart is the basic information for two antennas. It is shown that both antennas have almost the same performance in gain. However, the efficiency for flat antenna is better than tower antenna. In spite of that, tower antenna and flat antenna can reach the range of about 600m by using TX with the same output power and frequency.\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv\u003e \n
