I need to increase the range on my Heath-Zenith wireless doorbell.

I believe it operates on 315 mHz.

The antenna in the remote/transmitter looks like loop of length 1.5".
The antenna in the ringer/receiver is a wire 1.5" long that ends in
the breeze.

It would appear safest to lengthen the wire in the ringer/receiver to
around 7" but I do not understand why the manufacturer just didn't
make it longer in the first place.

Adding a random length to an antenna is not the way to improve its
performance. Bigger is not always better.

A more directional antenna, tuned for the right frequency/wavelength,
would solve the problem legally, but could cost more than the device
you own.

You might also consider what kind of structure is in between the two
points. Too much metal in the construction will interfere with any
radio waves.

Happy trails,
