This question is difficult to answer ..
For example, a 250mW transmitter with a good matching 50-ohm ground plane antenna or multi-element Yagi antenna can provide reasonably good signal strength up to a distance of about 2 kilometres ..
You ask about 4W ..
Without going into too much baffling technical detail, the answer is: ≈≈≈ the line of sight ..
There is no exactly in RF transmission.
It should be from 1Km to 5Km or more.
The range depends on,
- Antenna matching
-Antenna type
-Terraing
-receiver's sensitivity and antenna
In an area with a lot of buildings you may only transmitt to a few hundrets of meters.
