The Channel Master CM-4228HD is a good antenna, but it is very directional.
I did a generic plot for Pickens, SC: http://www.tvfool.com/?option=com_wr...e6a4329efc4408
The signals received at your location may very greatly depending on terrain, etc.
A few comments.
Channels 7 (CBS - coming from 56 degrees), 9 (PBS - coming from 83 degrees) & 13 (ABC - coming from 2 degrees) are VHF-HI channels. The CM-4228HD (like the Clearsteam 4) is not designed to receive them. It's designed for real channels 14 & higher. Both antennas have some gain for VHF-HI, but it's trial and error. You are better off installing a separate VHF-HI antenna and aiming it about 40 degrees). [Note: The "real channel" is the channel the station is broadcast on. The "virtual channel" is what the channel calls itself. Sometimes they are the same. Very often they are different.] The VHF kit for the C4 might have worked, but we don't know because you didn't try it. There are several possibilities for VHF-HI, including the Clearstream-5 and the Stellar Labs 30-2475 (MCM Part #30-2475).
The CDM-4228HD also has a narrow reception band. [It's similar to the DB-8e and you can see the pattern at https://www.antennasdirect.com/cmss_...s/DB8E-TDS.pdf
I would go with something like a DB-4e, which has an antenna pattern of https://www.antennasdirect.com/cmss_...s/DB4E-TDS.pdf
- that should be sufficient for your UHF channels, and if aimed properly, might even pick up MyN (WMYA) at 129 degrees.
You are certainly free to do what you want, but I recommend making a plot and posting it so we can assist you by providing the best options for your location. It saves work in the long run.
