Fitting for cable entry to home?
There are a couple of simple solutions. One would be a simple PVC raintight junction box. You would drill holes for the 2 conduits coming in and one in the back for entering the home. Use the right sized male adapters.  Be sure to caulk where it enters the home, esp. if subject to weather. If subject to severe weather you might look into using rain tight fittings (yeah, I know, nothings "really" rain tight, but we do our best).  You could also use an entrance ell (tee type) that has can accomodate 3 conduits.
