Title:
LOW RADIO WAVE REFLECTOR
Document Type and Number:
Japanese Patent JP2001144528
Kind Code:
A
Abstract:
To provide a low radio wave reflector whose mechanical strength can be enhanced without losing a radio wave reflection reduction effect of a foaming material.
A heat shrinkable tube 12 covers a formed foaming material 11 and heat equivalent to the shrinking temperature of the heat shrinkable tube 12 is externally applied to the heat shrinkable tube 12 so as to allow the heat shrinkable tube 12 to be closely adhered to the outer surface of the foaming material 11 and cured, thereby strengthening resistance to tensile stress and compressive stress of the foaming material 11 having weak strength.
