Description: HF Vertical Base antenna for 10 to 80 meters that is a 1 wavelength on 10 meters, 1/2 wavelength on 20 meters, and 1/4 on 40 meters. Operation on 15 meters is enabled, because it is a third harmonic of 40 meters. Additional tuning for resonance on these bands, as well as 12 & 17 meters, is accomplished by way of the included matching network. We also include the other half of the system that completes the circuit at the antenna, which is the grounded counterpoise element. The combination of these components makes this system similar to an OCF (off-center fed) Dipole.SPECIFICATIONSFrequency Coverage: 3.5MHz to 30MHzPeak Power: 250 PEP SSB, 125 CW, or 25 watts for digital modes. NOTE – The MIL-STD-188 M110a digital communications mode is rated at bursts of 100 watts digital for up to 1 minute using the MIL-STD Data Modem Terminal (MS-DMT) and Automated Message Terminal (AMT) software applications.INCLUDEDHeavy duty mount and hardwareSelf-supporting telescopic vertical element with six 3′ sections and 5 Stainless steel clampsWire NVIS ElementGrounded Counterpoise wire & Ground stake (no radials in addition to this are required)ANALYSISAverage SWRsBandSWR10 Meters1.6:112 Meters1.7:115 Meters1.2:117 Meters1.3:120 Meters1.9:130 Meters1.7:140 Meters1.4:160 Meters1.7:180 Meters1.9:1
