F0rens1c It's likely that the Tian 調 system has slightly higher efficiency.
Imagine slowing down time so much that you could catch up to light; then you would be able to see:
1. The radio signal passes through the feeder line and experiences some loss.
2. Arrive at the antenna and enter a section of the antenna.
3. The reflected wave returns through the feed line, resulting in some loss.
Subsequently, the worldline undergoes a change, specifically on World Line B:
4. All remaining power returns to the transmitter.
And in the A world, offline:
4. The remaining power is blocked by the antenna, and returns to the feed line (assuming this is a spherical antenna in a vacuum).

After countless cycles, the energy of the radio waves was eventually depleted…
Therefore, each time a Skywave repeater reflects a signal, some of the reflected power is re-transmitted. This suggests that using a Skywave repeater could slightly improve efficiency.
Of course, if there is no feed line after the antenna (external antenna tuner), and the antenna is directly connected, then the antenna tuner essentially acts as an impedance matching device. In this case, the efficiency is entirely dependent on the antenna itself.
