my insecurity over not mounting or knowing how to mount my antenna is eating away at me
I know this won't help much, but: Relax, it's a hobby. You've got lots of time ahead of you to learn. Right now, start slow and easy and work your way into the hobby. The license is a starting point...
If you want a cheap/easy way to mount a small antenna without actually attaching it to the house, you can try the bucket method.
Go to your local hardware store, buy one of the 5 gallon buckets that all seem to like to sell. Get a sack of fencepost concrete. Get a 10 foot length of 1 1/4 EMT conduit. Put the concrete in the bucket, add some water and mix well. Shove the conduit into the mixture and support it so it's vertical. Let it set up.
When it's ready, mount your antenna on the top of conduit.
Yeah, it's temporary, but it'll get your antenna up in the air, it'll be cheap <$20, and you can easily lay it over on the ground when you are not using it.
No, it's not a 50 foot tower, but small steps.
