In the real world, dealing with handheld and vehicle mounted VHF/UHF transmitters in the 2.5, 5 and 10W transmit power range, having local repeaters in high places like mountaintops or on top of 200m tall office buildings is extremely necessary for that repeater to cover even 1/20th of the land area of a western US state (WA, OR size).

I was referring to stand-alone stations - as in those with a simple GP antenna (VHF) and a half-wave dipole (HF), where there are no repeaters or other external devices involved.
