I have just purchased two 5.8GHz grid aerials from Polish company, one is quoted at 27dBi and other at 30dBi. My concern is the grid spacing, the 27dBi version measures 15mm and the 30dBi 22mm. These equate more to optimum Lambda /10 of around 2.3GHz and 1.3GHz areas, not 5.8GHz at roughly 4.5mm
Should I be worried or have others used these aerials with similar spacing with good results.
