Good evening. Unfortunately, the answer will depend on a lot of other parameters. For example, is there an obstruction, even temporarily, between the 2 houses? In your configuration, the energy emitted by a repeater is received almost in a single direction throughout the spherical radiation space. Think of your transponder as the sun, a big ball of energy, but only a tiny fraction of it reaches us on earth because the rest is radiated in other directions that are not aimed at the earth. To get round this, we need to multiply the antennas (sources) and also the channels on each antenna. This model works well in a configuration with wave reflections in an enclosed space, i.e. indoors. For outdoor use, unfortunately, you need to go upmarket (more antennas or channels) or install an antenna (or even a repeater) specially designed for outdoor use. There are even directional models that channel their energy in a point-to-point configuration. Don't forget that you need the same type of repeater on each side.
Personally, I always prefer to lay a good RJ45 cable whenever possible...
In itself, this repeater, which I use more on holiday in the houses I rent out, works well enough but mainly for indoors or just on the nearby terrace.
Best regards.
