Thanks for the reply, but this was for an antenna in my attic.
See subject line. -- I miss stuff in there too... ;-(
I don't know the actual OTA frequencies "we" are currently using
and I guess that is a major part of my question. (And if 450M is
still high enough.)
I did not test this "set-up" too much yet, but I have to figure
the signals coming from the old antenna will pass the same as they
always did through those old amps. Is the worst that can happen
the digital signal will flat-top/clip? Seems like that would
actually clean them up a little... (Wish I was sure..?)

Of you're talking digital cable you will need a distribution amp that covers 1ghz,
same with spitters & taps. 900mhz was the older CATV standard and I'd imagine that
450Mhz is old OTA broadcast spectrum.
Not having much output gain is not a biggie if your demarc signal is strong. Main
advantage to a DA is that it does not attenuate signal when splitting where passive
splitters do.
I definitely would NOT put a cable modem after a DA, especially a 450Mhz DA.

Good question, try it and let us know. Personally, I just got a
digital converter for my old Sony 27" and it works well with rabbit
ears. I get about a dozen stations because 2 of them have 2-3 channels
each which was unexpected. NTSC is dead, long live ATSC.
Duncan and "swzaske",
I found two old Broadband TV (distribution) amps.
One only had a 1dB gain, (but four outputs) so I skipped it.
(I may gang/chain them later in my attic for distribution on my second
floor.)
The other is a +10dB single output. Archer 15-1118 (very old, never used.)
50-450MHZ.

The OSD signal strength meter seemed to say it boosted the signal
around a little less than a third of the bar. (Red, Yellow, Green.)
This was on a channel that was breaking up, and it "cured that"...
I put it right at the VHF/UHF 75ohm rabbit ears to feed a converter box
from there.
I'll try it on my Desktop Computer next week.
(I'm working my way up from cheapest to most expensive stuff...)
