I have a 5.8GHz digital cordless phone system (two handsets and base
station) that has reasonable range. It works fine inside the house
and within about 30-50m of the house outside. The house is steel
frame clad with cementitious planking and plasterboard lining, and
has a steel roof.

Is it possible to improve the range of the handsets outside the house
using simple supplementary aerials or by relocating the base
station? If so where might I find design details?

I am competent with tools (I built the house) but don't know much
about radio.

The steel frame will act like a Faraday shield.
How far do you want the phone to work?

150m would be nice if it can be done without too much trouble.
