The O740ANT1 antenna is a complete, low cost design for light duty applications (typically indoors, through windows or skylights, but never where there is a lightning risk). This antenna has 30 dBi of gain and a 25’ RG-58/U coax lead with a male BNC connector. This antenna is for GPS only and connects directly to the SRS timing receiver. The antenna includes a marine style nylon ratchet mount which may be used as a stand, or used for permanent mounting of the antenna to vertical, horizontal or slanted surfaces.
