	Model:TOP608
	  excellent omnidirectional radiation characteristics. Compared with the traditional microstrip antenna, the antenna has four arm spiral structure. It has better low elevation gain and wide-angle circular polarization characteristics, and can receive more low elevation satellite signals.
	 The antenna has the characteristics of small volume, high positioning precision and light weight, and can meet the needs of users effectively.
	  Characteristic : quality is light. The total weight of the antenna is less than 30g, which is especially suitable for equipment such as unmanned aerial vehicle (UAV), hand held machine, wearable equipment and so on. It can greatly reduce the load burden.
	  easy installation. The antenna is fed and transmitted by a standard SMA joint, and the antenna joint is connected with the signal connector of the terminal device to fix the antenna without additional installation holes.
