800 metres with HB-100

Since I have discovered that from home I see a parking space 600 m away, I have just completed two tests with HB-100 TX and TV monitor+LNB RX.

At the parking spot the signal was loud and clear with plenty of SNR, so I can go further with this setup.

Then I took a longer route home and I stopped 800 m away on the same direction, and the signal could be received through reflections, but very very weak. Well, the TV monitor instrument is not as sensitive as an RTL-SDR, but there was no clear path between "me" and me.

NB: no dish was used on either side!

While measuring the distance on Google Maps I noticed that if you zoom in on the drawn path the line is black on "clear" and grey when there is an obstacle: helpful!
