Google faraday cage and you'll see why you have an issue inside.

Open a window?

As @PandJ2020 indicates, there are some fairly fundamental laws of physics at work.

Note that in this case I suspect you'd want a repeater with an external antenna, preferably on a longer cable so that the outside element can be located on or above the decking.

Also be aware that as Ofcom advises, many units advertised online are technically illegal to actually use, but strangely not to sell.
