Hello, Steve
Yes, it can be done that way. The hard part is determining the impedance of the open-wire lines from each antenna to the combining point so that when they are connected in parallel, you have 300 ohms for the balun. Forum member holl_ands on AVS and digitalhome.ca does modeling; he might be able to help you with that. He has worked out an open-wire harness to combine the two 4-bay antennas of the CM4228HD, which he calls the HHH.

While most TV antenna stacking is done horizontally, stacking vertically will give different results, but in some cases could work better.

Horizontal stacking reduces the horizontal beamwidth, but maintains the same vertical beamwidth of one antenna. Vertical stacking maintains the same horizontal beamwidth of one antenna, but reduces the vertical beamwidth.
