Friend has a situation where they have a second building on an adjacent property (semi rural)

they got the uniden phones with the repeaters in the charger hoping that it would reach the remote building, and it sort of does sometimes but it is really patchey as there isnt line of sight.

There is a fence that has good LOS to both places over about 80m to each of them which a repeater could be put on, but it would need to be powered. now as it only has to work during the day when they are working in the shed a cheap solar panel would do the job I expect, but does anyone know how many watts those repeaters use when in operation? I expect it wont be great as the handsets last ages on just AAA batteries.

The current usage is bound to be very low. But you will need to design, house, and build a solar charger, regulator, and supply some batteries so that the repeater works 24/7.

Just a thought, the easiest solution, and possibly the cheapest could be to bury some cable back to the nearest 230V outlet, and install the plug-pack supply there. As you are not running 230V over this cable, just the plug-pack output voltage (say 12v), you shouldn't need to meet any legal requirement, hence the installation of the cable can be quite rough.

I am guessing the distance back to the nearest 230V outlet is only a couple of hundred meters or so, and being on a farm, there is probably some attachment that can be put on a tractor to quickly make a trench for the cable to drop into.

Just thinking - outside the box!

That sounds like a pita. How about putting the repeater in the house and using a directional antenna?

I dont think I would need all that stuff, just a large enough panel to cope with overcast days, and plug it into the DC input of the base station - not charging a handset which I assume is the bulk of the load.

Sun out, repeater gets power, no sun, no power so no phone in the garage.

The other option is to try elevating the one on the house furthur - will talk to him about that. He just had the idea of putting one up on the fence and solarpowering it so thought I would look into that.
