How long is a 900 MHz antenna?
approximately 16.6cm
For a dipole antenna to operate optimally at its specified frequency, its length must be equivalent to a half wavelength of the operating frequency. In the 900 MHz range, this equals approximately 16.6cm (a full wavelength is 33.3cm).
What is the wavelength of 900 MHz?
33.3 cm

Which antenex antenna for 900 MHz?
Antennas at 900 MHz are pretty broad-banded. For mobile use, Comtelco Microloss 900 are good. Antenex also has some models for 900 MHz. Obviously always try and use the lowest loss feedline and connectors. The UHF connector (PL-259), should be avoided as loss at 900 MHz could be near 2 dB. RG-58/AU is also not desirable.
