Interference Plot

Coverage Plots

Note: all plots assume completely omnidirectional antenna. Yes, there are mild effects from the tower legs not yet shown here.

This plot depicts received signal strength at the mobile from the W4TTR repeater.

Standards

Time: 90%
Location: 90%
Repeater ERP: 200 Watts
Transmit antenna AGL: 1940ft.
