DB8e . Having 2 antennas of the same type aimed in the same direction to increase gain and connected correctly with the same length of coax and the 300 ohm connections connected correctly from each antenna to a coupler is Ok it has been done for many years.
Antenna stacking.
________________________________________________________________________________ ___
However having 2 antennas of the same type connected together and aimed in other directions , Will have problems with antenna cross talk and the phase timing deference of the two antennas receiving signals out of phase from the Tv stations in other directions. And a Looong list of other Well Known problems of reception.
Antennas Direct will have to Clearly State how the reception problems have been solved.
I know how to partly solve some of the problems , use directional couplers , however the directional couplers introduce some problems.
