George,
I don't know about this particular receiver, but in the early 80's, 450
- 950 Mhz was almost a standard input frequency.  Systems typically had
an LNA at the feed horn, then a short piece of large diameter coax to a
block converter mounted on the pole, then smaller coax to the receiver
in the house.
After the shift to 950 - 1450 Mhz and the combining of LNA and block
converter in one box, block converters became available to take the 950
- 1450 Mhz output of a modern LNB and convert it down to 450 - 950 MHZ
for people who wanted to replace their failed LNA or damaged dish with
modern stuff, but still use their old receiver.  Then later if they
upgraded to a modern receiver, all they had to do was get rid of the
extra block converter.  All you need is one of those old block
converters.
