79-ft. HybridDX™
vs. 135-ft. dipole.
w Optimized combination of horizontal, vertical, and efficient linear-loading! w Full legal-limit power handling. w 94% average Radiated Power (94.17w/100w, 4NEC2) across all HF bands (160-6m). w Superior to ordinary dipoles, G5RVs, and old-school wire designs. w Perfect for DX chasing. Great edge in contesting, too! w Up to 9x durability!* Patented design -- no linear tension on the antenna wire. The wire is suspended from the support rope by U.V. stabilized polymer spreaders. *770-pound break strength of 3/16" marine grade, U.V. stabilized, double-braided black Dacron/polyester rope vs. 213-pound break strength of 14 AWG hard-drawn copper wire or 85-pound break strength of 18 AWG hard-drawn copper wire. w Unsurpassed combination of all-HF-band tunability, efficiency, broadside performance, and weather durability. w The result of more than a decade of R&D with the latest technology tools and computer analysis, PLUS real-world use by actual hams. It's the dipole antenna -- reinvented -- for the modern era of ham radio.™ w 75 feet of quality 450-ohm ladder line included! For maximum efficiency, transition to quality coax via a 1:1 current balun (rated 1.8-54 MHz). Coax should be < 20 feet; the shorter the better to maintain efficiency. Connect to tuner, ideally external. INSTANTLY CUSTOMIZABLE ANTENNA PATTERNS: In seconds you can customize your HybridDX™ antenna to your precise operating needs. Our simple Antenna Clip-Up™ system lets you fine-tune the antenna
to create various antenna patterns.
4NEC2 analysis.
All wire types and conditions identical. Data at 60' AGL.
ADDITIONAL INFO: w Great primary QTH antenna. While no antenna is impervious to all weather conditions, the HybridDX™ gives you a distinct advantage for rough-weather survivability. w Excellent, no-compromise antenna for Field Day, emergency communications, etc. w Multiple U.S. patents issued and other patent IP pending. w 12 years of R&D. Initial prototype still in service after a decade of New England winters! w Designed and manufactured in the U.S.A. w The HybridDX™ system includes: Pre-measured / pre-cut solid copper antenna wires (18 AWG), 75 feet of quality 450-ohm ladder line, rugged feedline interface, ultra-durable 3/16" support rope, polymer spreaders, stainless-steel hardware, ring lug connectors (pre-soldered to the antenna wires), and complete instructions. TECHNICAL TIPS: You can easily optimize frequency matching without removing the antenna from the support rope. Just tweak the vertical wire lengths for spot-on tuning. It's another unique, ease-of-use benefit of the HybridDX™ antenna! As mentioned above, we recommend transitioning from the supplied 450-ohm ladder line to quality coax via a 1:1 current balun (1.8-54 MHz). There are excellent wide-range 1:1 current baluns from Balun Designs, DX Engineering, LDG, MFJ, and Palomar Engineers. Many of these have been tested with actual HybridDX™ installations. Why a 1:1 balun and not a 4:1 balun? The fine technical team at DX Engineering provides an excellent answer for all multi-band dipole-style antennas: "DO NOT match the balun impedance to the transmission line impedance. On non-resonant doublet antennas the transmission line is grossly mismatched. This means the impedance at the balun and tuner varies greatly from band-to-band. Tuners have an easier time with modest to high impedances. They don't work well into very low impedances. A balun with a ratio of 4:1 or more will transform the already low impedances appearing on some bands to even lower values. This will greatly reduce system efficiency and reduce tuner power ratings. The 1:1 ratio balun will just pass the low impedance through. In addition, higher ratio baluns will not handle differential impedance extremes nearly as well as 1:1 current baluns." https://www.dxengineering.com/techarticles/balunsandfeedlinechokes/baluns-choosing-the-correct-balun As is typical with multi-band antennas fed with ladder line, for optimal performance you may need to add or subtract an odd 1/8 wavelengh of feedline if a band is fidgety to tune. Please refer to this fine reference for additional info: https://kv5r.com/ham-radio/ladder-line/ladder-line-page-3/ The 79-ft. HybridDX™ is engineered to replicate the performance of a 135-ft. dipole antenna. All 135-ft. dipoles can be challenging to tune on 160m. Even so, with a wide-range 160m-capable tuner, solid performance can be achieved with the HybridDX™ on this band. The HybridDX™ has been tested on 160m with both modern and vintage tuners, including the MFJ-993B IntelliTuner™, MFJ-969 Deluxe Versa Tuner II, and Ten-Tec 228 and 229 tuners. As every home and installation situation is unique, experimenting with the length of your ladder line, as mentioned above, can be helpful.
