This antenna is supplied to operate satisfactorily within the frequency range(s) specified on the carton label. Some models require cutting of radiator and/or radials in accordance with Figure 11. If the antenna is to be used over a range of frequencies, the element lengths should be chosen for mid-range or favor the element length for the most used, or the frequency requiring the greatest range. ASSEMBLING THE ANTENNA 1) Select antenna location and route cable from set to antenna.
Lengths on chart are approximate. For finer tuning, use a VSWR bridge if antenna is to be used for transmitting. Remove vinyl cap before measuring and cutting. Slide vinyl cap back on after cutting.
