Missing channels with new Ant install

[stbabu]

Hi, guys, just read through a bunch of posts, but not seeing anything that looks like it'll help my issue. I have an RCA ANT751R that I just installed on my roof. I'm getting about 16 channels, although none of them have great signal strength. My problem is that I'm missing WXIN and WISH and I can't seem to get them to come in at all. I DO get WTHR. My antenna is pointed at 247 degrees and it's about 25 feet up. I can't figure out why I can't see them at all. I chose this antenna after reading good reviews on Amazon, I thought it should be decent quality. Anyway, here's my report: http://www.tvfool.com/?option=com_wr...9e74ec2e5a5e39
Anybody have any ideas what I'm doing wrong?

What type and how many feet of coax? Is it new or reused?

Any splitters? If so, how many ports & how many sets are actually connected?

Any amplifiers? If so, what make and model?

Do you have an FM trap installed?

Have you tried replacing the matching transformer at the antenna?

Your location has a long list of LOS = Line Of Sight digital channels that are Very Strong Signal Strength. How many Tv's are connected?? I recommend new RG-6 coax from the matching transformer at the antenna to the connection at the house. The matching transformer connected to the antenna can be defective. I recommend connect a known to be good matching transformer to the antenna and connect a known to be good 'long' coax to the matching transformer and run the coax direct to one Tv. No splitters , No grounding blocks , No amplifiers of any type or kind , No amplifier power supplies or power injectors , No splices. Now what do you receive??

You're doing nothing wrong. The antenna selection is valid. The aiming is correct.

Look for a bad connection, water in the coax, bad balun, bad splitter, etc. Sometimes even new stuff is defective.
