* Massive high-efficiency trap assembly gives the strongest signal possible on both bands * Unique fold-over antenna mount features DX Engineering's patented pivoting fixture, U.S. * 5 kW SSB and CW rated for unparalleled reliability The DX Engineering 8040VA-1 Dual-Band THUNDERBOLT® Vertical Antennas feature: An optional CW optimizer DXE-7580-THK capacity hat kit allows for adjustment down to a 3,400 kHz center frequency for dedicated CW operators and military/MARS operations. This means that operation on the CW DX frequencies and DX Phone frequencies is within range of most radio internal tuners, so no antenna changes are necessary to switch frequencies. The 80/75 meter band is tunable down to a 3,650 kHz center frequency with a 300 kHz bandwidth. They also use the same radial system for both bands.ĭX Engineering 8040VA-1 Dual-Band THUNDERBOLT® Vertical Antennas cover the whole 40 meter band with one setting. They are perfect for areas where there is no room for individual verticals. dual-band vertical antennas supply performance which is virtually indistinguishable from our monoband vertical antennas. A greater number of radials improves performance, but radial length is not critical for a ground mounted vertical antenna installation.Īdditional Information HF Vertical Antenna BandĭX Engineering 8040VA-1 Dual-Band THUNDERBOLT® Vertical Antennas are high performance vertical antennas specifically designed for the 75/80 meter and 40 meter bands.
