I have Sirius XM radio in both of my cars. It works everywhere, except some overpasses and all tunnels. No matter the direction I am traveling. So my wife wanted to use it at home. I purchased a small unit with a cable and presumably, a patch antenna on a hinged box. The orientation and angle of the antenna are super critical, and even then, doesn't always work, with continuous dropouts. Is it just the antenna, or is the receiver just a piece of junk? If it is the antenna, how do I get or make one that works. I have the antenna outside, pointed to the South.

What cable are you using between the antenna and the receiver?

The patch antenna (magnetic brick type) needs a ground plane to work correctly.

I think the Quadrifilar Helix Antenna (QHA) may help you. It works in any direction. Have a look at:

UC-2334-431LA, Satellite Radio antenna, LHCP, +22 dB LNA

Wow! $100 for a radio that costs less than$50?
And that radio does not support power for the LNA. I checked.

Bad antenna - bad or no reception no mater of the radio cost.
You can ask the antenna manufacturer for a suitable power injector or have someone make a Quadrifilar Helix Antenna (QHA) with a power supply.
