Preliminary Urban VHF/UHF Radio Noise Intensity Measurements in Ottawa, Canada

Measurements of the VHF/UHF radio environment were carried out over a 17 day period in November 1976 at four sites in downtown Ottawa. The radio noise parameters, Fa, (the available noise power spectral density) and Vd (the voltage deviation) which both relate directly to the performance of communication systems, were measured. The measurements tested the feasibility of using commercially available equipment to make such measurements. The Fa values were computed for a discone antenna which is different from the short vertical monopole usually used In measurements of the radio environment. The results compare favorably with those published in the literature.
