That chimney is dead in the signal path to Boston. If you swap from a C4 to a DB4e (for example), the extra height of the DB4e will mean that half of it will be below the chimney, rendering half of the antenna ineffective. The shorter (vertically) C4 *might* be the better choice, depending on what improvement you're targeting or seeking. My best technical advice for reliable reception would have to be "don't put the antenna behind the chimney".

Thanks again.
Re distribution: We previously had cable. The system has a some sort of preamp. One of the feeds went to a 3 way splitter in the attic. I reversed the cable, fed with the antenna and changed splitter to 4 way, now antenna feeing cable distribution system. I needed a preamp before the 4 way splitter RCA tvpreamp 1Z which helped a lot.
I have taken a TV directly to the antenna in the cupols and am getting same signal.
Overall, seems like I'm doing as best as I can. Lowest signals are 4 bars and look great so I'm sure many would envy my concerns. D B 8 seems like would not be big help.
Many thanks. Bob
