本活動では、電波を反射する道具のうち、木製の板の片面をアルミ箔で覆ったものを電波反射板と呼ぶ。電波反射板は任意の厚みで420×594mmすなわちA2判（一般的な国内の新聞紙１ページ）の大きさに等しく、その広い面にアルミ箔を貼り、地面に対して垂直に立てて使用する。電波反射板の底面は現地撮影時刻に「だいち2号」が地上に向けて照射する電波と直角に接する方位に合わせて配置する。電波反射板は《たかはぎ座》の活動で初めて用いられた。
Of the equipment used in this project to reflect radio waves, those made of wooden boards with one side covered in tin foil are referred to as “plate reflectors.” The plates are of A2 size (420 x 594 millimeters; size of a standard domestic newspaper page) and of any thickness. One face of the plate is lined with tin foil, and the reflector is used by standing it perpendicular to the ground. The bottom edge of the reflector must be set up directly facing the direction of the radio wave fired by Daichi 2 towards the ground at the time of imaging. These plate reflectors were first used for Takahagi Constellation.
