Know before you buy
The kit provides the essential components for a wire antenna installation, including one DELTA-C center insulator with an SO-239 connector, two CIN end insulators, and a SEP ARC-PLUG static protector. It also comes with heavy-duty 12-gauge PVC-coated copper wire and stainless steel hardware.
The SEP ARC-PLUG is a replaceable gas-discharge device designed to protect your equipment from static buildup. While it is highly durable, you should inspect it periodically for signs of damage or after a significant nearby lightning strike to ensure it remains functional.
Deltalloy is a specialized, high-strength plastic engineered specifically to resist degradation from intense UV sunlight and fluctuating temperatures. It is designed to remain rigid and intact over years of outdoor exposure, preventing the brittleness often seen in standard plastics.
Yes, the kit is designed to be flexible for custom wire antenna builds. You can cut the included 12-gauge copper wire to the specific length required for your target frequency, using the provided strain relief holes on the insulators to secure the wire properly.
The center insulator is built for outdoor use, but it is always best practice to apply weather-resistant coax sealant or tape around the PL-259 connection once it is attached to the SO-239 port. This prevents moisture from wicking into your coaxial cable over time.
