Yes, you can repurpose your satellite-dish coax cable for terrestrial reception, however, you must be sure that there are no power injectors,amplifiers, satellite diplexers or other passive devices hidden on the coax line that can potentially interfere with reception. be aware, however, that if you are running long cable lines, and are distributing to more than one Tv set that you will probably want to use a preamplifier.
There are many bogus TV antennas on the market. Some of them will work for close-in reception, but will be worthless for fringe areas. My rule of thumb is this: if it doesn't LOOK like a real TV antenna, then it won't work well more than 20 miles or so from the transmitters: Disk-shaped antennas, oblong antennas and devices that look like chiropractic devices are usually not good antennas.
Many people like the Clearstream antennas: I don't have enough experience with them to wholeheartedly recommend them, however. The Clearstream 4 is sold as a fringe-area antenna, and many people like it, although it is clearly not as powerful as the XG-91 that I recommended: even the manufacturer says that. Will it be adequate in your area: I can't say for certain, but, since they offer a money-back guarantee, all you have to lose is your time and the labor to install it.
As for the relative size of the antennas, even the XG-91 is small when compared to the full-sized VHF antennas of bygone eras: it has a relatively low profile, and is quite light. I also believe that the argument about depressing the value of your house to be specious. 25 years ago, almost EVERYONE had some sort of antenna on their roof, and, given where you live, I am sure that they were large antennas, as the desirable TV stations are quite far away, and large antennas were a necessity to see ANY TV reception.
