I replaced the Winegard amplifier with the Winegard SensarPro RFL-342 this weekend. The new one lacks an external port so I had to install a box where I drilled a hole in it so I could run a feed line for the bedroom TV.
Before.
New box with feed line for bedroom TV.
Factory splitter feed for external TV and bedroom TV.
Finished install, the SensarPro did nothing to add channels in the valley where we have our rig however. :(
