Improve Antenna TV Reception and Detect Interference using the RTL-SDR USB as a Spectrum Analyzer

Improve digital over-the-air TV reception and detect interference, including from 5G & 4G LTE cell towers and FM radio stations with the $30 RTL-SDR USB, a $7 adapter, and free open-source software! In this video I show how to measure the signal difference between antennas, the beneficial/detrimental effects of adjusting an antenna, and potential interference sources. As featured on RTL-SDR BLOG!: https://www.rtl-sdr.com/troubleshooti... TV CHANNEL NUMBERING IN THE UNITED STATES Lo-VHF Television band (channels 2 - 6)*: 54 - 88 MHz Hi-VHF Television band (channels 7 - 13)*: 174 - 216 MHz UHF Television band (channels 14 - 36)*: 470 - 608 MHz https://en.wikipedia.org/wiki/Pan-Ame... *With digital television, the channel number a station appears on your TV set as does not necessarily match the radiofrequency (RF) channel number it is actually on. Many TV stations now use "virtual channel numbering" and transmit on a different RF channel than what they appear as. Use https://www.rabbitears.info/ to identify the actual RF channel number of a station.
