The CDH centre fed dipole is a robust antenna designed for use in areas of adverse weather conditions and for higher input power (500 watts) Because of its heavy duty construction it will withstand a higher wind velocity than the standard folded dipole.The balun is encased in a reinforced and watertight ABS enclosure and potted with epoxy resin for added protection. If required, the antenna can be etch primed and powder coated in various colours to add further protection against atmospheric pollutants such as acid rain, sulphur and sea spray
