settings.
7. Setting of right gain value to get the best performance
To get the best RF per ormance o your wireless system, setting of right value of
antenna gain is important. Allways start with setting the gain, which covers losses o
your coaxial cable. Losses o common types o coaxial cables are in the table on page 8.
I signal indicator on your receiver indicates very weak signal even i you set the
gain which covers coaxial cable losses, you can try to add more gain and get
better per ormance. For example in places with low RF noise this gain can add
multiple working distance o your wireless system.
