An improvised weapon is not a ranged weapon. You can only add DEX to attacks made with ranged weapons. Ranged weapons are a group, not a property.Ranged isn’t a weapon property.
Attack Rolls and Damage
You add your Dexterity modifier to your attack roll and your damage roll when attacking with a ranged weapon, such as a sling or a longbow. You can also add your Dexterity modifier to your attack roll and your damage roll when attacking with a melee weapon that has the finesse property, such as a dagger or a rapier.
Throwing an improvised weapon gives it a range, but does not make it a ranged weapon.
