Описание: Supercharging a Classic: The “Super Rybakov” Antenna Build

This Club Talk from the Halifax & District Amateur Radio Society introduces a hands-on build of the “Super Rybakov” – an improved version of the classic end-fed vertical antenna. If you’re working with limited space but want efficient, multiband HF performance, this presentation is packed with insight.

What It Covers

Antenna Design:

Extends the classic Rybakov design to a 43 ft vertical using a 12m Spiderbeam pole and extension.
Uses just two elevated counterpoise wires—no need for a field of ground radials.
Loss Reduction:

Explains in plain terms where antenna efficiency is lost and how to fix it.
Covers transformer mismatch, poor soil conductivity, and feedpoint SWR issues.
Practical Build Tips:

Full walkthrough of how to mount, extend, and tune the antenna.
Homemade solutions for fittings and supports.
Advice on using a remote tuner at the feedpoint for better performance.
Performance Results:

Field-tested across multiple bands.
Notable gains:

20m band: up to 12 dB stronger than a traditional doublet.
30m and 40m also showed significant improvements.
Still usable on 80m with ~19% efficiency.
Why It Matters

If you’re operating in a small garden or need something temporary and stealthy, this is a serious option. With just two counterpoise wires and no radials, it offers real performance—especially on 20m and 30m—without needing a complex install or high budget.

Max (G4SDX) doesn’t just give you theory—he shows you how it performs in real life, what worked, what didn’t, and where the biggest improvements came from.
