I'm interested in building a cantenna to improve GSM mobile phone reception in a fringe area.
My grandmothers landline has had frequent faults lasting several weeks, and she is quite isolated. I know I could get a yagi for about GBP40 but that doesn't stop me being a cantenna enthusiast!
The freqencies involved are 900 or 1800 MHz. Preferably 1800 to use orange.
Cheers, Alex
