28' HF Vertical Antenna
The Uncompromised DX Powerhouse. For the Ham operator who refuses to be unheard. This high-aperture radiator dominates the low bands and hears the weak-signals that ground-mounted verticals miss.
Smart Ham Physics
Proprietary Vertical Dipole Antenna (VDA) technology off-center-feeds this 28' radiator, bypassing the need for ground-radials, providing higher efficency and lower noise floor for weak-signal DX without the list of hassles.
Strong Materials
Heavy-wall 6061-T6 Aircraft Aluminum. Rated for 80+ MPH winds. This is a permanent property asset designed to outlast a lifetime of solar cycles.
Elegant Freedom
Tactical LVP profile. The uncompromised stealth solution for the serious operator in a restricted QTH who needs a big signal without property value impact.
UNLOCK 5/8 WAVE GAIN (+3.5 dBi)
Pair this 28' mast with our 9' DX Whip to hit the 5/8 wave "Golden Ratio" on 20M, 30M, & 40M. Effectively double your power at the horizon.
