I've been trying to recive NOAA automatic picture transmission (APT) pictures for a year now.
I never got a picture with V-dipole, so I decided to build a double cross antenna. I used 75 ohm coax because here in Italy I can't find 50 ohm cable. I used galvanized gardening wire for making the dipoles. Why is there no signal? (Sometimes I see it but SNR is only 5 or 10 db.)
If this can help I live in south Italy, in a city named Messina. I have a DVB-T USB stick (RTK820T2.) I built the antenna with wood. I even tried to use a fridge door as reflector. Nothing. I tried all possible settings and softwares. Still nothing. My antenna is at 2 meters up from the ground. I would really like to hear your possible solutions.
