VHF Antenna for Standard Horizon Radios
The direct answer: any marine VHF antenna works with a Standard Horizon radio — antennas are universal. Fixed-mount VHF radios all use the same standard 50-ohm connection (SO-239 socket, PL-259 plug). What actually decides your range and how long the antenna lasts: construction, gain, cable and connector quality.
Standard Horizon fixed-mount radios, including the popular GX1400, use the standard SO-239 socket. The GX2400 and GX6000 add AIS receive — pair them with an AIS-capable antenna.
What actually matters when pairing an antenna with your Standard Horizon
- Connector. Your Standard Horizon (GX1400, GX2400 Matrix, GX6000) has an SO-239 socket. Every Scout antenna ships with the matching PL-259 — and the QuickFit line removes the soldering step entirely.
- Gain, matched to your hull. 3 dB holds the horizon on boats that roll; 6 dB reaches farther from stable platforms. The gain guide explains the trade in two minutes.
- Construction. The radio is only as good as the antenna: Scout builds every model 100% foam filled with solid brass/copper elements and AISI 316 stainless hardware — and in nearly two years of US sales has had zero warranty claims.
- Cable run. Quality cable ships in every Scout box; keep the run short and solder-free where possible. The installation guide covers routing.
Scout picks for Standard Horizon owners
- Scout KS-41 — 4 ft / 3 dB: small boats, T-tops, and anywhere windage matters. QuickFit solderless option.
- Scout KS-42 — 8 ft / 6 dB: the classic center-console and cruiser pairing, 25–30 mile range.
- Scout KS-43 — 8 ft / 6 dB collinear-phased: the best-performing antenna in the range.
- Sailboat? See the full range for masthead 3 dB antennas and dedicated AIS antennas.

Common questions
What VHF antenna works with a Standard Horizon radio?
Any marine VHF antenna. Fixed-mount VHF radios — Standard Horizon included — use the industry-standard 50-ohm antenna connection with an SO-239 socket that accepts a PL-259 connector. There is no such thing as a "Standard Horizon antenna"; what matters is antenna quality: construction, gain, cable and connector.
Does Standard Horizon make its own VHF antenna?
Standard Horizon sells radios; the antenna is a separate purchase from an antenna maker. That is good news — it means you can pair a Standard Horizon radio (GX1400, GX2400 Matrix, GX6000) with the best antenna for your boat rather than a bundled compromise.
What gain should I choose for a Standard Horizon radio?
Gain comes from the antenna, not the radio. The honest rule: 3 dB (usually 4–5 ft) for small boats, sailboats and anything that rolls — it holds the horizon as the boat moves; 6 dB (usually 8 ft) for stable powerboats that want maximum range. Radio brand plays no part in that choice.
Do I need a special antenna for Standard Horizon AIS features?
Some Standard Horizon radios include AIS receive. AIS lives at the top of the marine band (161.975 / 162.025 MHz), so a well-built broadband marine antenna serves both voice and AIS through one connection — and Scout also builds dedicated AIS antennas for split installations.
