Chris,LF,Presumably by increasing the height one increases the capacity and the the radiation resistance and thus the ERP will rise for a given TX power and antenna current? One probably also reduces the loss resistance too, due to needing less loading L, so the current might also increase, leading to yet more ERP for a fixed TX power. John GM4SLV |
