What you use depends on what works. Your 5 channels in green are all UHF and all at 305 degrees on a compass. They are all reasonably strong, so you might try an indoor antenna (a UHF antenna, rabbit ears are for VHF although they do gather some UHF signal). See what they have at your local stores and try it (save the receipt).
Since you have a 6' pole in place, adding an antenna should be a simple job (assuming the pole is the right diameter). It will be far more reliable and less subject to indoor electrical interference. For a fairly inexpensive solution I'd consider any of the following:
-
Eagle Aspen EASDTV2BUHF - $27
-
Clearstream 2 - $80
-
Antennacraft U200 - $25
There are numerous options.
