What is the maximum range of the TA-312/PT?

The TA-312/PT is a field telephone that has specific operational ranges dependent on the condition of the line used – whether it's wet or dry. The value attributed to the maximum range of 14 miles wet and 22 miles dry reflects its performance capabilities in various environmental conditions. When operating under ideal, 'dry' conditions, such as good line quality and minimal interference, the TA-312/PT can transmit signals over a longer distance, reaching up to 22 miles. Conversely, 'wet' conditions, which can hinder signal quality or introduce additional resistance, typically limit its maximum effective range to 14 miles. This distinction in range based on environmental conditions is crucial for planning operations where reliable communication is necessary.
