Thank you to "Double A" for submitting his latest YouTube tutorial video that shows how to use an RTL-SDR together with the Spektrum software to optimize TV reception by comparing TV antennas, repositioning antennas and detecting interference.

Double A's video first shows how to setup the RTL-SDR and how to install and use the Spektrum analyzer software. He then compares a popular highly rated phased array TV antenna against cheaper log periodic TV antenna, with the results showing that the phased array works a lot better at most TV frequencies even with accurate positioning. He goes on to show how he scans for FM, 5G and local electronics interference and the effect of an FM filter can help.
