You can see the antenna and trees here. http://s251.photobucket.com/user/DogTi/library/time?sort=3&page=1  I'll let it run and check on it now and then.  Now if I had the XRef from VK3HZ.

Unless I'm looking at the pictures wrong, you still have a lot of trees around the antenna. An ideal setup would be clear of obstruction to within 10 degrees of the horizon from about NE around through due S and back up to NW. It's rare that you get 100% of that ideal. If you are obstructed to > 45 degrees over most of that range the TBolt will be struggling at certain times of day. It'll struggle more when it's raining if the issue is trees.

That's more a matter of luck than anything else. Google maps isn't all that accurate.

Your property line may or may not be defined in same reference frame GPS uses. You'll have to do some research on how it's defined.

The best way is to take a look at the source code. The other way is to just poke at it and see what comes up.
