When I moved my rack to garden and mounted an indoor sensor in library at far end of basement things took longer to be discovered.
While testing my outside mount for Sky2 box under my roof line I kept knocking off the antenna. I finally via it's magnet stuck it to my metal roof. Instantly everything was discovered from garden to basement.
I have moved box back inside for more testing but the antenna now resides on a fruit cake lid. I now never get a timer tick before everything is discovered.

Good ground planes work wonders with antennas!

I had the same problem - in spades!
Moved my WeatherRack outside; about 200' from the "base" and it flat WOULD NOT connect.
I moved the base to a window overlooking the WeatherRack, still about 200' away, still nothing.
So, I build a 433 Mhz dipole - Pictures to follow; but here are the basics.
I had an extra whip antenna with the cable and MCX connector - cut the cable, separated shield and inner conductor, got two plastic covered metal paperclips from my wife and straightened them. Turns out they're just shy of 6.5", which is the length for each side of a 433 Mhz dipole. So, I just soldered the paperclips to either side and reinforced the center with a little electrical tape - connected and rebooted - PERFECT signal!
I'm gonna take it down tomorrow and figure out a way to "pot" it and permanently mount it on the outside of the box; but I'm definitely in business!
