Question: Analog Ch 25 comes in great

The Fool Report: TV Fool

I only recently realized that analog 25 was in a totally different heading (azimuth) than my other channels. Had been watching very poor reception on it, until just now and I turned the antenna and it comes in strong. Analog 25 is the same as digital 4-1 which is KRON 4 broadcast on digital real channel 38.

Only 8.8 miles away. I had assumed analog 25 came from the same location as it's digital version, namely Sutro Tower, but that's not the case.
