  • Page 129 This antenna is supplied to operate satisfacto- rily within the frequency range(s) specified on the carton label. Some models require cutting of radiator and/or radials in accor- dance 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.
  • Page 130 Lengths on chart are approxi- mate. For finer tuning, use a VSWR bridge if antenna is to be used for transmitting. Remove vinyl cap before measur- ing and cutting.
