I know, the title is a little obscure.
I placed my Raspberry with a DVB-T stick and the antenna (1/4 wave, stylo) near my router, with the antenna posed on the frame of the aluminium window, at last floor of the building.
This way I get a coverage only in a restricted beam around 240° and receive aircraft until 210 miles.
The Raspberry was connected with a cable, and now via wi-fi.
When all was working, I placed the same hardware on the flat roof (a terrace), which is not obstructed and the antenna has a 360° sky visibility.
Now, I get a near 360° coverage BUT ONLY UNTIL 40 Miles and no more!
All is the same, antenna cable, hardware, position, only the place is 3 meters high. The only thing different is the distance from the router: it will be possible that a weak signal interfere with the coverage? I believe it is impossible, but why placing the antenna in a better position DECREASE my coverage?
Perhaps will be a saturation problem? I don't have any RF source in the neighbor...
Any suggestion?
Than you!
