THE ADVANTAGE OF PROPER ANTENNAS:
Strong radio power can give longer range but strong transmit power is only half the solution.
Receiver power on this same antenna is the other half of the answer. Receive signal is very
much affected by the noise oor present at the site (static). The source of noise in the environment
range from digital products of all forms and other radio communications. Antennas are everywhere
so look around and try to minimize the noise to the antennas for both the TWIG units and the TD200.
Even weather conditions can limit communication because moisture in the air weakens signals.
BEST PRACTICES FOR ANTENNAS:
The antenna is the backbone and focal point of the network. Make sure that the location is carefully
selected. The basics are:
1) Locate the antenna only high enough to clear line of sight obstacles. It is a lightning target so do
not go up higher than necessary.
2) Minimize the antenna cable length because cable does cause some amount of signal
degradation. Route the cable in locations where it won’t be damaged.
3) The cable connections are the greatest source of trouble so make them carefully and use the
connectors sealant tape provided in the antenna kits.
4) Use the specied surge arrestors that come with the kit. Substitution of cable, connectors or
surge arrestors is at the installer’s own risk and it can be a major source of service troubles.
5) Use approved grounding methods. It may save your system from big damage!
INSTALLATION SIMPLICITY (TWIG identity):
For convenience, the TWIG address identity is labeled on the outside of the TWIG. Write each
address identity onto the eld map. That makes it simple for the controller startup when assigning
valves to groups.
TIP! Keep a copy of the eld map at the controller. It can be a great tool for managing the irrigation
system.
Remember the signal between antennas on the
TD200 and the Repeater are stronger than the
signals from the TWIGs.
