Grid 16N antennas sold in packets of five are put into one cardboard box.
The antennas in such packets are to be assembled by the recipient.

This model is DC-grounded i.e. more resistant to overvoltages, caused e.g. by thunderstorms. Very stable characteristics, small size. Radiator employs wave-guide technology. Antenna to be used by clients as well as in base stations (e.g. as sector antenna). The antenna can work in any polarization (one can recognize the polarization by the grid).

Mostly, the antenna is installed in vertical polarization. Polarization type can be easily changed, by turning the mount by 90 degrees. The position of the radiator must not be changed, nor can it be unscrewed. If the antenna has to cooperate with a slot sector antenna, the polarization must be set to horizontal (as in the picture below). To avoid water getting inside the antenna, it is good to grease the screw thread.
