Figure 10. Typical Omnidirectional Antenna
At remote sites and point-to-point systems, a directional antenna, such
as a Yagi is generally recommended to minimize interference to and
from other users. Antennas are available from a number of manufac-
turers.

Feedlines

The choice of feedline used with the antenna should be carefully consid-
ered. Poor-quality coaxial cables should be avoided, as they will
degrade system performance for both transmission and reception. The
cable should be kept as short as possible to minimize signal loss.
For cable runs of less than 20 feet (6 meters), or for short range trans-
mission, an inexpensive type such as Type RG8A/U may be acceptable.
Otherwise, we recommend using a low-loss cable type suited for 900
MHz, such as Heliax ®
