Low Band Dipole Covers 160-80-40 meters with an overall length of only 100 ft. Antenna performance and 2:1 VSWR bandwidth is site dependent and varies with height above ground and surrounding objects. The typical bandwidth is: 160M – 20kHz • 80M - 40 kHz - 40M - 300 kHz Full band coverage can be accomplished with an antenna tuner. Built with insulated 12ga. wire, stainless steel hardware and uses the Model DELTA-C static protected center insulator and CIN end insulators. Use coax or open wire line and configure as a dipole or inverted-V. Assembled and ready to go!
Regarding RF power, the instructions say this of their model DX-LB.
160 and 80 meters, 600 Watts CW/PEP, ICAS duty cycle. 40 meters, 1000 Watts CW/PEP, ICAS duty cycle. (Intermittent Commercial & Amateur Service... 50% duty cycle, 5 minutes on then 5 minutes off) RTTY is limited to 250 Watts to prevent overheating of components.
