Not that I know of. The TV antenna input is to pass through outdoor signals to your TV set if you are in the mode to send the TV your FTA pictures on channel 3/4. (an idea I do not support) The SD receivers have no OTA tuner.
AND, for the record, the few HD receivers which have an OTA tuner are pretty awful, IMO! You are much better off finding a better solution.
This may not appeal to ya, but I had a Silicon Dust, HD Home Run dual tuner recommended by Linuxman. It hooks to your computer LAN, and works GREAT!. I got a $15 remote (new, Amazon), and used the Vista Media Center software on my laptop. The tuner was a refurb for under $100, last year. He just got a used on one craig's list today, for $40. :up
