TIGHAR hypothesized that the Electra’s belly (receiving) antenna was lost on takeoff from Lae while the dorsal (transmitting) antenna on top remained untouched and intact. From the USCG radio log, it is clear Itasca could hear Earhart, but she could not hear them .. so the proposed scenario fits at least that part of the known evidence. I won’t comment on the alleged “post loss” messages.
