This is a 55 years old single-story house with stucco exterior wall all around. The stucco does have metal wires inside.
The cable will be going to a 3/4-way splitter to 3/4 TV outlets.
I've tried a few others and I am using an RCA-ANT121 non-amplified indoor antenna right now placed above and connected directly to the TV in the living room (no splitter right now). This seems to be a good low-cost indoor antenna I've tried so far compared to other low-cost indoor antennas.

The output goes to a Channel Master CM-7000.
I am able to pick up KRON (4), KPIX(5), KQED(9.1), and KTEH (9.2), KNTV(11) for VHF channels.
Does not pick up KTVU (Fox) or KGO (ABC) in the scan.
Being able to pick up the channels in the scan doesn't imply I can view the channels. At most I can see KRON/KPIX (I need to keep switching the knob). I cannot see any VHF channels at all at night. Maybe KRON--with frozen image--sometimes. I need to turn the knob to find the spot where it works.
For UHF, I can pick up KTSF (26.1) KMTP (32), KICU (36) KCNS(38) KSTS (48) and the PBS channels (54.x), ION (65), KFSF (66.1), KDTV (66.2).
Does not pick up KTLN (Ch 47) or KACA-LP in the scan.
Among these UHF channels, I can only view KICU(36)/KSTS(48)/PBS channels (54.x). No signal/picture for all other UHF channels.
I don't know if other indoor antennas would be any better... .
Perhaps the stucco/stucco wires are blocking the signals from going inside the house? If so, then I'd need an outdoor antenna.
