Spiderbeam Aerial-51 Model 807-HD Asymmetrical Dipole Antenna – Heavy-Duty, Multi-Band HF Performance

 

The Aerial-51 Model 807-HD is a full-length, heavy-duty wire antenna built for serious HF amateur radio operators who need reliable performance across the 80m–6m bands. Designed in response to high demand for an 80m-capable version of the popular 404-UL, the 807-HD brings durability, high power handling, and wideband capability to permanent or semi-permanent installations.

This asymmetrical dipole covers 7 primary HF bands plus 6m, and optionally 30m with reduced performance and a tuner. It delivers strong signal output, low SWR near resonance, and the rugged construction needed for long-term outdoor use—even in challenging environments.

 


Key Features:

 

  • Covers 80m / 40m / 30m / 20m / 17m / 15m / 12m / 10m / 6m

  • Handles up to 600W SSB/CW (except 30m: 150W with tuner)

  • SWR (typical): From <1.5 to <2.7 depending on band

  • Antenna Length: approx. 40.8m (134 ft)

  • Weight: approx. 800g (1.5 lb)

  • Optimized for 12m height or higher (Inverted-V or Flat-Top)

  • Constructed with CQ-532 copper-clad steel wire (breaking strength 50 kg)

  • Teflon-insulated SO-239 coax jack with gold-plated contacts

  • Hybrid Balun + RMU (Region 1 version) – Balun is epoxy-potted for weatherproofing

  • Built to suppress common mode current – avoids issues common with other OCF dipoles

 


Ideal For:

  • Base stations and semi-permanent outdoor setups

  • DXers, contesters, and HF enthusiasts wanting full-size performance

  • Operators in HOA-restricted or rural locations

  • New Zealand hams needing efficient, multi-band HF capability

 


Installation Tips:

 

Mount the feedpoint at 12m (or higher) using a fiberglass pole, aluminium mast, or tree. The antenna can be installed as either an Inverted-V or a Flat-Top Dipole. Use any 50-ohm coaxial cable (keep it lightweight if mounting on poles). The included Region 1 RMU is tuned around 3.670 MHz for optimal performance on 80m in IARU Region 1.

 

Height = Might! For horizontal HF antennas, height above ground directly impacts performance—especially on low bands like 80m.

 


Looking for Lightweight?

 

For field use and DXpeditions, consider the Model 807-L – a special lightweight version using Poly-Stealth 22 wire (available on request).
