The covarge map below assumes the following setup: 50 watt radio with a quarter, half or five eigths wave antenna mounted on the vehile in such a way as to not introduce major losses or severely distort the antenna radiation pattern. The plots are based on "near full quieting" signal, allowing for some flutter or "picket fencing". Actual usable coverage will vary based on antenna and how much noise can be tolerated on the signal. The coverage map was made with Radio Mobile software.
147.105 coverage for typical mobile station:
