All building materials were made fire-resistant to protect against incendiary bombing. Treatment involved a vacuum process of salt impregnation. During construction, high winds caused a partial collapse of some members. The ruined materials were piled for incineration, but would not burn; so the rubble was buried on site. Years later, a farmer leasing ground on the site plowed up some of the materials. They were reported to still be in good condition.

"Driven by the need to understand the characteristics of radio communication in Canada's North, Canadian researchers focused on the exploration of the earth's upper atmosphere, the ionosphere. Canada's satellite program commenced with the launch of Alouette-I on September 29, 1962. Alouette-II followed in 1965, ISIS-I in 1969, ISIS-II in 1971. The Alouette/ISIS tracking antenna serves as a reminder of Canada's contribution to this international effort in space science.
