Ground system
The CG-3000 must be connected to a good electrical ground. Good ground
prevents shocks, interference and others.
Use heaviest gauge wire or metal strap available to connect to as large as
possible metal object.
Install a quarter wave length of working frequency wire as counterpoise.
Attention
1.
Check the supply power to tune. If the power voltage is too low, CG -
3000 will not work. And DO NOT reverse the polarity of the input power.
2.
To ensure the proper tuning, the antenna must have enough length.
3.
Do not install BALUN, it will cause difficult tuning.
4.
Reduce the transmission coaxial cable as short as possible.
Calculation of undesirable antenna lengths
Length of half wave = 300 / operating frequency (MHz) X ½
Please avoid using the antenna length that is close to a half wave or multiple of a half wave in length
