SDR dongle and Digital OTA TV

[spongella]

Even though you can't watch digital TV stations in the US using the dongle, you can still get a spectral display of the signal. TV digital signals are 5.97 MHz wide so the dongle cannot display the whole spectra, but every DTV channel's signal begins with an ATSC pilot ( or "spike"). Here's an example of one attached. This is a station from Philadelphia.

We'll I have a Question, " about vhf outdoor tv antennas, and what do you think about either" vertical stagger stacking them," or HORIZONTAL STACK side BY side, and what should I use for cable, RG 6,;18 Gage solid copper,or RG 11,with a Johansson amplifier,One in at, 30 B/Vhf; ,and Two uhf,in at /40;D B, and with Two:91XG on top,; witch will be 90Ft high, and the vhf antennas at 85Ft high,!!!!73,to everyone and have a good day,

Way above my head, sorry. RG/6 is good coax. Good luck with your installation.

Horizontal for TV signals and solid copper RG6 if using a amp. Just make sure your antennas are at least a wavelength away from each other and use a decent combiner.
