How to use
Mount the antenna in the direction of the desired GPS satellite reception area to take advantage of its directional gain. Connect the male RP-BNC connector to the matching RP-BNC input on your receiver or RF cable using compatible adapters if necessary. Ensure the antenna is firmly fixed and oriented for optimal line-of-sight to satellites; indoor placement near a window facing the sky can improve reception if outdoor installation is not possible.
Usage recommendations
For reliable long-term outdoor use, install the antenna on a stable mast or bracket and route cables through weatherproof grommets. Avoid obstructions in the antenna’s line-of-sight and verify compatibility with your receiver’s connector type and 50 Ω impedance before installation.
