First I tried elevating the antenna. No joy. It seems the extra wire is a big negative. It might be worth looking into a signal amplifier to drive the extra cable.
Went back downstairs and connected with original cable. Now have 26 synced channels.
Tried putting some AL foil on the back as a reflector. The board is 3/8 thick and there is NO reason to expect that the reflector spacing is in any way appropriate. Hung from light valence (about 10' off floor on second floor). With elements facing N, re-scan got 19 channels.
Turned antenna so the elements were facing S. Re-scan got 17. This is not looking like an improvement.
Took foil off. Re-scan got 23.
It looks like foil at 3/8" isn't helpful.
Next I made another version using AL foil tape. Got 26 channels. Of these there are 18 that have good reception and are in English! Here's what the unit looks like:
