Basic physics applies - unless it has an amplified splitter builtin,
then it will have to have an unamplified splitter and will be the same
as using a four way splitter yourself.  Given this text on that web
page:

"This is a 4 digital TV tuner card with one antenna input, you must
supply it a good quality digital TV signal to operate it properly (see
under system requirements), if you are in an area where the signal is
marginal, this product is most likely not suitable, consider single or
dual tuner devices  for your situation."

then I would think that it virtually certain that it only has an
unamplified splitter.

However, you can always add an amplifier splitter to your aerial
system yourself.  In which case, it would be better to have a board
with multiple aerial inputs such as these:
