If you don't want to go on your roof, you can hire an installer to do the work for you. There is a link at the top of the forum to connect with an installer. The installer could also advise on what antenna would work best for you. And you would also get some kind of assurance that the installation will work correctly.
Hiring someone to help you could be a good investment. Realize that your antenna installation will be a one-time cost, and your cable bill is a continuing and increasing expense. Spend money now, save money later.
You are right, the CV2 is not intended to receive VHF low, and WMC 5 may not come in very well, if at all. I believe there are few antennas specifically designed to receive VHF low. With the right signal combiner, you could add an Antennacraft Y526 to the CV2 and aim it at Memphis.

Roof mount antennas that will cover all these channels are available. Look at the Antennacraft HD series -
