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.

To keep your visitors from ringing your neighbors' bells?

How would increasing the size of a receive antenna increase
propagation from the remote?

If you had said "To keep your neighbors' buttons from ringing your
bells," that might have been valid.

No one said it would. You should read more slowly.

No, I was responding to the bit about "why the manufacturer
just didn't make it longer in the first place" -- the manufacturer
intended that the receive range -- on all units -- be short enough to
avoid this problem. If he made it longer, everyone might ring bells
for a couple of houses on either side, as well as their own.

My button rings my neighbor's bell and his rings mine. We both bought CHEAP
wireless doorbells.

====================================

Have you tried swapping them ?

Good Idea,

I did this too, my lady next door it hot,
she answers the door in her cami * panties all the time,

when I want to take a peek I just press the
button and wait to see her.

She can't figure it out..

Well, how's about positioning a web cam/video camera so we can all enjoy the
view???

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,
