I don't know how "rectifying the RF" got into this subject, because it
doesn't appear to me to have anything to do with the question.  D2, D3
and D4 are all forward biased by a solid (not varying) +8 VDC in the
receive mode, while D1 and D5 are forward biased in the transmit mode. 
An RF signal has nothing to do with this.

The low-level RF signal present in this circuit (in either xmt or rcv)
certainly will not overcome the 8 volts of bias on the diodes and will
not even come close to exceeding the 600-volt peak reverse rating of a
1N4005.
