Directional antennas are used for Point-to-Point or sometimes for Multi-Point systems depending on the setup. If you are trying to go from one location (say for instance your router), to another location, this is the type of antenna we recommend. Directional antennas are Backfires, Yagi, Panel and dish type antennas.
The hinges they sell for such gates are rated 'Holds up to 2000lbs' etc. The gate will be 13' wide, and weighs a little under 200lbs even distributed across. So how do you figure the weight? 2000lbs straight down, or 2000lbs cantilevered out 13 feet? There is a big difference in the two, and with a gate it's kinda tricky - a little of the weight is straight down but as you move further away from the hinge post, the effect of the weight gets greater.
Special Hinges Spring NFPA 80 has restricted the use of architectural grade spring hinges to fire rated doors of a maximum size of 3â0â x 7â0â (914 mm x 2134 mm). Hager spring hinges have been tested and labeled for up to a 4â0â x 8â0â(1219 mm x 2438 mm) door when a minimum of three springs are used.or doors up to 2-1/4â (57 mm) thick, the hinge is set back 1/4â (6.4 mm) from the back face of the door.3. For doors over 2-1/4â (57 mm) thick, the hinge is set back 3/8â (9.5 mm) from the back face of the door.Once these dimensions are known, the formula can then be applied.
