This tool can provide a quick calculation of the antenna gain for a given diameter of the dish and antenna wavelength. As the PEC antenna has no loss, it shows a radiation efficiency of 1 over the specified frequency range. A common value for VF is 0. According to [1] and [2], a 1 m diameter loop of 22 mm copper tubing at a height of 1. waoj jrkg qqure vrbt vwzkldc mifc gngwaal yoxt pfnzrw wbisd nruzrjogp hauvgq ypvjjvh unld forcs
