If analog W46DK (real CH-46) is not on the air (The FCC database indicates the license expired in 2005) WPKH should not have adjacent channel interference to contend with. That would make it easy to receive with a 4-bay panel such as a DB-4, CM-4221, U4000 or HD4400. Aimed at 36° compass, the beam width would allow for reception of the stronger WTJP signal also.
The problem then becomes how to combine the signals from two 'same band' antennas. Some people are successful to some degree using a common 2-way splitter in reverse. That however is quite often the source of multipath interference which causes interruptions to signals that were revived well by one antenna. A more reliable option would be to use Jointennas or equivalent channel insertion filters. You would need one for each real channel (45 & 26). Warren Electronics may still have new-old-stock Jointenna product. TinLee.com (in Toronto) is a custom builder of various filters and is now one of the last options available to the OTA community. Some people find A/B switching less expensive and more reliable.
You also have the option of terminating the second antenna in one or two of the HD HomeRun tuners... An option
I have had running successfully for some time now.
It sounds like you have some RG-6 and CAT-5e cable to run...
