Doorbell for modern plastic door

I think the problem is that the frame is reinforced with metal, usually where the transmitter is fitted and I guess this shields the signal.

Best solution is a wired doorbell.

It is possible to buy a doorbell extender which will convert wired to wireless.

Yes. I've seen them, but you'll have to Google as I can't recall what the make was...

I tried a couple of cheap ones, and they were variously unreliable and drained batteries quickly.

I've since bought a Friedland (on recommendation from here I think) basic model and it's worked perfectly, and still on the same set of batteries after at least a year. Button mounted on the UPVC door frame, bell about 6 yards away.

Just a year? When we moved into our current house the Friedland (wired) doorbell batteries were orange Everready HP2s and God only knows when these were last on sale.

Yep. I have one of these and it works well:

I do have an old-fashioned door, made of olde worlde 'timber'; there's a conventional period doorbell pushbutton on the outside, and it's wired to the Byron transmitter which is on the inside of the door. I can't imagine having a door or frame made of another material would make any difference

Only problem with my doorpush

Is that the plastic is yellowing after less than 2 years, would probably replace it with the black version.

I was able to drill and thread cables (doorbell and alarm contact) through the uPVC frame while installing my front door door so there's nothing visible.

I often find the portable non plugged in ones work better than the plugged inones. I have a theory that this is due to the amount of crud on the mains from powerline addaptors and switch mode supplies deafens the reciever in the bell, wheas the battery operated worn type bells are higher up and not near the mains and hence work better.

The main issue I had with wirelss bells though was that there are now so many around spurious operation from another bell push is a real possibility. Brian

wires and transformers are always better than radios and batteries as far as I'm concerned.

With my current Friedland unit it also has the intelligence to know when the push button battery is going flat and sends a different code to the receiver - the bell unit works as normal and then gives a second tone to say 'replace the battery'

Chris brought next idea :

I have installed lots, with never any such problem - The secret is to buy a quality unit, like Friedland's 100m range ones.

Not with a good quality one, which has unique coding - Friedland.
