Guy Wire 100 ft 20 Gauge 6 Strand Galvanized Antenna Support Cable

Our review of this Guy Wire 100 ft 20 Gauge 6 Strand cable finds it is a straightforward, no-frills support line for rooftop antenna and mast installs. Installed by a technician or a handy homeowner, the biggest reason to buy is the combination of length and flexibility: 100 ft of six-strand, 20 gauge galvanized steel gives enough reach and manageable handling for most residential aerial masts. This review focuses on real-world handling, the basic installation tools required, and whether the cable delivers the durability and tension needed for common off-air antenna setups.

Key Features

• 100 ft length: Provides ample reach for tying off masts to distant anchor points without splicing, reducing weak points in the support line.
• 20 gauge, 6 strand construction: Balances tensile support with flexibility so it is easier to bend around turnbuckles and clamps during installation.
• Galvanized steel finish: Offers corrosion resistance suitable for outdoor use on roofs and masts exposed to weather.
• Minimal tools required: Installs with common hand tools like wire cutters and pliers, avoiding the need for specialty equipment.
• Multi-use support: Works for antenna masts, aerial supports, and other light guying applications where a discrete, thin support line is preferred.

Who It's For

This guy wire is aimed at homeowners, hobbyists, and small installers who need a long, thin support line for rooftop antenna masts, off-air aerials, or light radio antenna supports. The length and flexibility make it a sensible choice for rigs that require runs up to 100 ft or where routing around roof features is necessary.

It is not intended for heavy industrial use or to replace thicker, higher-gauge aircraft cable where substantial load-bearing or safety-critical guying is required. Professionals fitting large towers or commercial structures should choose heavier gauge cable designed and rated for those loads.

Pros & Cons

Pros

• Long 100 ft spool reduces the need to join sections, keeping anchor points simpler.
• Six strand 20 gauge construction gives good flexibility and easy handling during installation.
• Galvanized finish improves outdoor durability for rooftop and mast exposure.

Cons

• At 20 gauge this cable is for light support only and is not suitable for heavy or safety-critical guying.

Our Verdict

The 100 ft 20 gauge six strand guy wire is a practical value for homeowners and small installers who need a long, flexible support line for rooftop antenna masts. It is best when used for light to moderate loads where a discreet profile and ease of handling matter; those needing heavy-duty or safety-rated guying should select a thicker cable. For typical residential aerial installs it represents a cost-effective and durable option.
