Direct antenna for TV HAT for different channels

Fri Mar 01, 2019 4:21 pm

I have a TV µHAT and live close to at least two different TV broadcast towers (Jägersro, Malmö, Sweden & Copenhagen, Denmark) that are about 45 degrees apart here. I try to change the direction of the antenna and use this oneliner in Raspian Stretch to find the best direction for each TV transmitter:

Code: Select all

while true; do femon -c 1 -H | sed '1d;s/.*signal  //;s/ |.*//' | xargs toilet -f bigascii12.tlf -F gay ; done
I would need a better method that could select a channel and measure its strength for TV uHAT, because the TV transmitters have different channels and if I measure the total signal I get signals from both broadcast towers at the same time.

I don't have another TV receiver for Denmark (MPEG-4, DVB-T & MPEG-4, DVB-T2 & DVB-T2 Lite).

Do you know how to measure the signal strength of a channel or a MUX using TVHeadend or the command line?
