28' HF Vertical Antenna: Uncompromised DX Powerhouse 160-6M

This is the antenna that gets you back to the pure joy of radio—maximum performance, with minimum fuss.

The 28' HF Vertical Antenna (v2, $2\text{" OD}$ model) is the choice for the modern operator who demands uncompromising efficiency and durability. Built for those who prioritize a powerful, low-angle signal, this antenna delivers world-class $\text{DX}$ without the back-breaking work of installing a massive radial system. It's the smarter core for your station.

Is the $28\text{’}$ HF Vertical Your Perfect Antenna?

This antenna was designed for you if:

✅ You are a serious $\text{DXer}$ or Contester who needs the lowest possible angle of radiation to break through pileups.

✅ You need a rugged, field-deployable system suitable for Government Agencies, $\text{EmComm}$, $\text{POTA}$, or $\text{SOTA}$applications.

✅ You want the technical advantage of $5/8$ wave-capable gain on key bands without a massive tower structure.

✅ You value superior, $\text{American-made}$ engineering built with $T6061$ aircraft aluminum for a lifetime of use.

The Greyline Advantage: Smart, Strong & Elegant

• $\mathbf{dBi}$ Gain Potential: Every Greyline $\mathbf{VDA}$ is engineered for universal gain across all bands. Utilize our extensions to precisely tune your system's electrical length and maximize $\mathbf{dBi}$ output on your key operating bands, achieving up to $3.5\text{ dBi}$ of low-angle power.

• Strong Engineering (Rugged Reliability): Constructed with $2\text{" OD}$ heavy-duty $T6061$ aluminum and stainless steel hardware. This is a commercial-grade antenna designed for $100\text{+ MPH}$ wind loads, ensuring mission readiness in any environment.

• Elegant Performance: The sleek, professional profile is a clean and effective radiator with no unsightly traps, coils, or clutter to fail. Seamless elegance and silent operation.

Upgrade Your Performance: Optional Extensions

Take your 28' HF Vertical Antenna to the next level or the moon with these powerful, easy-to-install upgrades. Low bands never looked so good.

The 4' Extension: For the Serious Low-Band Operator

Adding this 4-foot, heavy-duty section increases the electrical length of your antenna, noticeably boosting its efficiency and performance on 80 and 160 meters. If you love chasing DX on the low bands, this is a must-have upgrade.
