Every foot of coax takes a cut, and the cut grows with frequency. Pick a cable and a run length to see the loss in dB, the power that actually gets radiated, and the cable length for a stub.
What the feedline takes, and what reaches the antenna.
Every foot of coax costs you signal, and the loss climbs with frequency. This shows the real toll for your cable and run.
Figures assume a matched line. High SWR adds extra loss on top of what’s shown here.
