pretty sure the smaller one is an original Channel Master 4221 UHF antenna.
Should be still good. My understanding is that is a quite desirable antenna since the new one (4221 HD) is not as good; performance wise.

VINTAGE CM4221 UHF antenna
Good find !
It's made by Channel Master [when they were actually made in America] but it's a pre-generation 4221 design. A CM4221 has aproximately 7 3/4" 'V' elements and they are lighter gauge than what I see in the pic. The screen width of a 4221 is 20" and the one in the pic looks a little bit narrower. The wider CM4221's were made in China by the same people who now make the CM4221HD.
It would be worth your while to just clean it up a little and give it a shot. It may not work as well if you change the elements. Be careful handling the plastic element mounts as they will likely be quite brittle.
I am not an OTA expert but I imagine that, like beauty, it is what is inside that counts. The conductive properties of the metals will have changed very little with the surface corrosion. It may be hard on the eyes though.
The big VHF/FM Yagi is definitely a Channel Master and it looks like one of the shorter range Crossfire 361x models probably from the mid-1980s. For Montreal-area people like yourself it would get ABC 13 from the U.S. beautifully.
Using old antennas is fine if they are designed to pick up the channels you desire and you take some precautions before mounting them. See "Is it okay to used an old antenna?" in Post #3 in the OTA FAQ
I'm thinking the large VHF one is a log-periodic since I thought that one of the characteristics is that the rod electrical connections crisscross down the length of the boom. But it's hard to tell for sure since there's no top down view to observe the rod spacings.
I was thinking of setting it up at my BIL's but I would have to add the missing element, and then he still wont get the digitals...not much point eh...
another option could be combining this with a proper GH or mclapp, point the VHF at the strong locals (VHF) with the UHF one on top. I'm not sure if this worth while in comparison to using one unique antenna, namely the DBGH NAROD...
