Eight bands from a single no-radials vertical. The center-fed elevated dipole design reduces ground losses and removes the need for a radial system, with continuous coverage under 2:1 SWR on 10m through 40m plus ~100 kHz on 80m. It handles 1500W PEP on 10-40m and 500W on 80m, needs no tuner on most bands, and uses linear decoupler rods instead of lossy traps. It is self-supporting at ground level, and the elevated feedpoint means ground quality does not affect performance (concrete, rooftops, any surface).
25 feet tall and 25 pounds (a substantial installation). It does not cover 6m or 2m. The 80m bandwidth is narrow (~100 kHz). 30m can be problematic (some users report high SWR). Performance is still a compromise versus dedicated monoband antennas. It is installation-sensitive (nearby objects affect tuning). The assembly instructions could be better, and some users add guys in high wind despite GAP's no-guy claim.
A no-radials 8-band HF vertical. For operators who cannot install a radial field (concrete patios, rooftops, HOA restrictions), the Titan DX provides genuine multiband HF coverage without ground dependence. Many operators have earned DXCC with it.
The GAP Titan DX is the flagship of GAP's distinctive line of HF verticals, an eight-band antenna covering 80, 40, 30, 20, 17, 15, 12, and 10 meters that, unusually, needs no radials or earth ground. GAP's design feeds the antenna at an elevated point with a built-in counterpoise tube, sidestepping the large radial field that a conventional ground-mounted vertical demands, which makes it a favorite for operators with limited space or rooftop installations.
At about 25 feet and 25 pounds it is a substantial but manageable vertical, rated at 1500 watts PEP on 10-40 meters (500 watts on 80), and it is designed as a no-tune antenna with usable SWR across each band straight out of the box. As with all multi-band verticals it is a compromise compared with a resonant antenna on any single band, and the lower bands (especially 80 meters) have limited bandwidth, but the all-band, no-radial convenience is the whole point.
It is a current product. The radial-dependent Hustler 4BTV is the traditional alternative, and the no-radial Hy-Gain AV-640 covers similar ground.
