LSRA coverage depends on a number of factors and this image depicts when best conditions align. This is a science for some hams.
This map speaks to VHF coverage when using the VHF1 - 146.850 repeater. VHF1 is on the best antennas at the site.
VHF2 - 147.315 coverage is less, as the repeater is on a lower set of antennas.
UHF - 442.575 coverage is about 25% less, this is the norm with this frequency.
Power: 100 watt amplifiers are in use on the VHF1 / VHF2 / UHF repeaters. This has helped to fill in some coverage holes in difficult terrain. Other repeaters or links run in the 25w range..
Coverage wil depend upon:
- line of sight
- where the antenna is mounted on a car
- frequency used
- antennas on use at the LSR site
- weather - UHF does not like wet leaves.
