VHF Antenna Cross-Reference & Comparison Table
Last updated: September 2026
Every Scout marine VHF antenna side by side — length, gain, real-world range, cable, and price. All models share the same 100% foam-injected, IP69 waterproof construction with solid brass and copper elements.
Antenna cross-reference table: Scout vs Shakespeare vs Digital Antenna
Replacing an antenna you already own? Find its length-and-gain class below and the Scout model that drops into the same mount. Every antenna listed uses a standard 1"-14 thread and PL-259 connector, so the swap is mechanical, not electrical. “Comparable” means the same class by length, gain and mounting — construction, cable and price differ, which is what the head-to-head pages cover.
