We have commercial cellphone beam antennas available in South Africa. One
model is made by a television antenna manufacturer and another is made by a
professional communications antenna manufacturer. The beams are fitted with
about 15m of coax and a connector.
These beams are usually bought by users in rural areas where the signal is
marginal. They certainly work well.

Subject: [Antennas] Cell Phone
| Has anyone attempted to extend the range of a cell phone by building a
gain
| antenna?
|| I have an older analog only phone which I think operates in the 800 MHz
| range. The antenna is about 3 and 1/2 inches - (1/4 wave on 800
MHz?????).
| I also have a newer phone which operates in either the 800 or 1900 MHz and
| the antenna is approximately 4 and 1/2 inches (3/4 wavelength at 1900????
| and close to 1/4 at 800????)
|| I like to use the phone from home and sometimes the "cell" is marginal.
Any
| ideas?
