The power_mw field represents the beacon's effective radiated power, not just transmitter output. Relabel it as "TX power (EIRP)" on the form and detail list, "EIRP (mW)" in the index, and drop the now- meaningless tx_gain_dbi constant in RangeEstimate since the stored value already includes antenna gain.
