Doorbell issue

[Funboythird]

We live in an old Fenland farmhouse and our back gate, where the post and most deliveries arrive is - in a straight line - about 30 metres from our back door. Unfortunately, there is an old brick-built tractor shed, which we use as a garge/potting shed, directly between the house and the gate which impedes any wireless doorbell signals. I am currently on the third bell kit, a Technet unit with a supposed range of 400 metres, but it still only works intermittently, and more often than not we rely on the dog to hear the postman arrive, much to the ongoing consternation of said postman! It is frustrating to miss deliveries, which then have to be re-arranged or collected from the nearest delivery office, which only opens for 1 hour, on three days when there's a z in the month.

I am wondering if there is any way to enhance or improve the signal so that it will pass through, around or over the shed and actually activate the ringer unit in the house. The only alternative as I see it is to install a wired system on a mains-powered transformer, which would mean digging a trench to lay cable ducting. Given the distance, would I still have any issues with power loss through the bell wire, considering the comparatively low voltage of such a system? There is electrical power in the tractor shed, where a bell transformer could be installed.

Any thoughts?

Would it though? Why do you need to bury the cable?

But you have a building with power in it, with short line of sight to the house, and short line of sight to the gate. Must be a way to link the two inside the building?

Would a wireless repeater or range extender on the outside of the shed resolve the problem. Speak to Technet.
