I have two antenna mounted in my attic (approximately 25 ft. above ground) pointed towards the Baltimore and Washington DC markets. Both antenna are joined with a 2:1 splitter which is connected to an RCA amplifier. I installed the amplifier due to a pretty long cable run (approx. 200ft) to my basement. Unfortunately there isn't a more direct path without drilling floor to floor so it runs the length of the house in the attic and down through my vinyl siding then to my media center in my basement. The cable is then split 1:2 (one feed to my 2nd floor bedroom and one feed to my HD Homerun). With the long cable run there is some signal/channel loss in my bedroom feed however the feed over my LAN is pretty good (picture below).

I access the HD Homerun via PLEX on my ROKU 3rd generation and iOS devices. It would be ideal if I could pull in Baltimore WBAL 11 and WJZ13 which are the same direction and distance as WMAR 2.1 ABC Baltimore. Any thoughts on what I might need to do? Would a preamplifier work? Should I switch Antennas?
