Rock 95 Seven,
I recall that you are in a mobile home park and that is why I suggested some ideas about a stealth antenna. Unless you actually try it, I don’t think it is going to be possible to predict your range with any indoor antenna. My indoor here gives about 150 feet with a cheap portable radio. I can provide details if you are interested. The loading coil design is probably not going to be the “magic bullet” you seek but it may be worth a try.
Do I read between the lines correctly that you may not be able to do any external antenna work yourself? I need to make a few assumptions here. One is that your power in your home is of the three wire variety. That’s your ground; the screw on the cover plates. The second is that there must be a way to extend a 3 meter wire out a window to get your signal out of the “cage”.
Congratulations on your baby and keep your family your first priority.
