This is my observation having gone down the same road with a Metzo. To get out a mile, you truely need to use a base-loaded antenna as shown on the Sstran website or the MLR antenna shown here. That, along with a proper ground, will give you the coverage you want.
When I had my Metzo, I tried everything with the 3m wire: grounding, elevation, tuning. Nothing helped until I built an antenna for it.
The cost to build is about $20-$30 for the parts, but it is labor-intensive. Most of the work is in coil-winding.
The difference in coverage with this antenna is dramatic and it’s worth the effort.
