Cannot record programs

Hi to everyone ! I scanned for all of the channels available and apparently that was successful.
I have tried to record a few programs, however it appears that the recording only lasted 1 second… Upon checking my Tablo phone app, it appears that the connection had a weak signal.
Any suggestions ? I have heard that this a reoccurring problem.

I assume you have used a site like antennaweb.org to determine what channels are available, in what direction, what type of antenna is required and if the antenna signal might need amplification.

Signal strength does mean there is signal quality. Sometimes just re-adjusting the antenna will clear the problem - or make it worse.
