This is only true for VHF frequencies that require line-of-sight to work
properly (which would be of limited use in this scenario). It is not true
at all for HF frequencies, which can transmit information over long
distances (such as across international territorial boundaries).
For VHF and UHF, which can actually support very high bit rates, you would
need compatible equipment at all nodes. Each node (hop) would need to be
able to "see" two other nodes, which would each need to see two other nodes,
etc.. The maximum physical distance from node to node would be dependent on
each node's physical horizon. Setting up a[nother] network of nodes across
long distances using these frequencies is going to be very difficult and
expensive.
HF radio frequencies that enable reliable communication over long
terrestrial distances don't have enough bandwidth to pass large amounts of
data. 1200 baud is the maximum legal rate that Ham Radio operators can send
using the 10 meter band, which ~28-30 MHz. ("CB" is ~26.xx-27.xx MHz). And
the 10 meter band is not always reliable over long distances...
