Fablication method of radio absorptive in γ-Fe_2O_3/TiO_2 composite materials for VHF and UHF band are studyed. The system which utilizes γ-Fe_2O_3/TiO_2 materials have been studied and their matching thickness with absorbing bandwidth are discussed. The absorption properties of the radio absorptive of 1.3 cm in thickness and 140 MHz in bandwidth centered at 1300 MHz is demonstrated as an experimental example.
