It does sound like there’s something wrong with your Talking House – even with the wire antenna, you should get more range than that.
But to answer your question, the easiest way to get range is to use the matching ATU, combined with a whip antenna. It works very well, and the range that I got, at least, was good – up to a mile or more with noisy but listenable reception in with a good car radio.
Now, if the problem is with the tuning mechanism in the TH, going with an external antenna will solve your problem. But if it’s something else, then no antenna will solve your problem. I would attempt to track down the actual problem before spending any more money. The build quality of the Talking House is not all that great – I own 3, and 1 of those just didn’t work out of the box (something in the internals).
