The invention discloses a composition for manufacturing an antenna base and a method for preparing the base. The composition consists of an 
epoxide resin, a curing agent, an accelerating agent, alkali-free chopped epoxidized 
glass fiber filament yarns, an 
ultraviolet absorber or a screening agent, nano-
quartz powders, a defoaming agent, a 
thickening agent and a dye, or consists of a vinyl resin or an 
unsaturated polyester resin, a 
red material, a white material, neutral alkali chopped epoxidized 
glass fiber filament yarns, the 
ultraviolet absorber or the screening agent, the nano-
quartz powders, the defoaming agent, the 
thickening agent and the dye. The preparation method comprises the following steps: respectively weighing various raw materials in 
mass ratio; putting the 
epoxide resin, the curing agent, the accelerating agent and the alkali-free chopped epoxidized 
glass fiber filament yarns into a stirrer to stir uniformly until the foams disappear; then adding other raw materials, sufficiently stirring the mixture to form a ball mixture; and putting the ball mixture on a heated base die, closing the die and carrying out stepping heating and curing, and naturally cooling and disassembling the die to obtain the antenna base. The antenna base has the advantages of tensile strength of over 18kN, strong 
impact resistance, strong 
ageing resistance or 
ultraviolet resistance, good 
flame retardance, good 
toughness and high electrical insulation, and is widely used for army and 
wireless telecommunication equipment.
