10Broad36 was less successful than its contemporaries because of the high equipment complexity (and cost) associated with it. The individual stations were much more expensive due to the extra RF circuitry involved, however the primary extra complexity came from the fact that 10Broad36 was unidirectional. Signals could only travel one direction along the line, so head-end stations must be present on the line to repeat the signals (ensuring that no packets travel through the line indefinitely) on either another, backwards direction frequency on the same line, or another line entirely. This also increases latency and prevents bidirectional signal flow.
