OPERATING TIPS The following conditions tend to reduce the effective range of two-way radios and should be avoided whenever possible. Operating the radio in low areas of terrain or while under power lines or bridges. Obstructions such as mountains or buildings between the vehicle sending and the system/person receiving the message. In area where transmission or reception is poor, some improvements may be obtained by insuring that the antenna is veritcal (particularly if a glass mount is used). Moving a few yards in another direction or moving to a higher ...
