I am getting pretty good OTA reception with the antenna/reflector I mounted on my roof, here is a breakdown of my system:
1. RCA ANT 751 mounted about 7' above my chimney, about 25' AGL
2. 4' wide by 3' high parabolic reflector I made out of aluminum bars (I bent the two ends myself) with construction screen as a reflector material
3. RCA TVPRAMP1R connected to mast
4. 25' (approx) of Audiovox blue RG6 coax running from ANT to power unit of pre-amp, goes immediately into a Radio Shack 3.0 GHz 2 way splitter
5. From the splitter, 10' of Audiovox blue RG6 coax to one television and 35' of Audiovox blue RG6 coax to the other television (runs under the house)
Here is my TV Fool report:

I am having trouble with KPIX, KPPX, and KTSF (all UHF, I believe)
From reading many posts, and without a background in electronics, I believe the only thing that would help is more antenna. I want to stick with a rear mounted system so that it will work with the reflector I built (based on how many more channels I got after building it, I think it is the single largest contributor to my reception), and I think I can infer from context that it is possible to add element to a factory made antenna to increase gain (many people have added VHF element to UHF antennas, but nobody that I could find has added more UHF to UHF)... but I see references to dipoles/spacing/ etc. from smart guys and it makes me hesitant to just buy another antenna, cut off the UHF element and bolt it to my RCA ANT 751 (which does work pretty well). I have submitted a question to RCA about modifying the antenna, but have waited a week with no response.
Can anyone tell me if purchasing another antenna (or the same antenna?), cutting off the elements and attaching them in some symmetric fashion to my antenna would be a benefit? I'm not worried about the efficiency of cost; I just want a system that works better long term.
Thanks!!
