Something else to keep in mind is that the westernmost site that is being referenced in the diagram above is located at the Miccosukee village and generally only carries traffic on the tribe’s talkgroups and one of MDSO’s districts , Hammocks IIRC. My experience has been that this particular site can be monitored roughly as far west as Carnstown on Tamiami Trail. This is using an SDS100 with an external 7/800 MHz antenna. As for the Miami-Dade sites that carry public safety traffic (site 102), the best coverage to the west has been on Tamiami Trail just before the Miccosukee tribe. In contrast, I have monitored the Collier P25 from south Dade while on the turnpike.
