Larch Mountain-Capital Peak radar and communication radio frequency interference survey

John J. Tary; T. Layne Livingston

Abstract: A theoretical study of the radio frequency interference (RFI) environment has been performed for an existing communication complex that uses VHF, UHF, and microwave communication equipment and is located On top of Capitol Peak in the State of Washington. The study includes predicted desired-to-undesired ratios to be expected with the possible installation of a WSR-57M weather radar system 1 mile away at Larch Mountain.
