The Shakespeare 5400-XT Galaxy is a 4-foot, 3 dB antenna from the Galaxy line: shorter and lighter than an 8-footer while keeping Galaxy construction, with a wider signal pattern that works well in rough water.
Who it’s for
- Smaller powerboats, bay boats, and skiffs
- Installations with limited height
- Sailboats wanting a rail-mounted backup antenna
Key features
- 4 ft length
- 3 dB stated gain
- Galaxy-series construction
Choosing the right antenna
-
Gain vs. beam: a 3 dB antenna has a wider signal pattern that keeps working when the boat rolls or heels, which suits sailboats and rough water. A 6 dB antenna concentrates the signal toward the horizon for more range on stable powerboats.
-
Height is range: VHF is line-of-sight, so mounting the antenna higher does more for range than extra gain. On a sailboat, a short masthead antenna usually outperforms a long antenna mounted low.
-
Coax matters: RG-58 is fine for short runs; RG-8X loses less signal over longer runs; RG-213 is the choice for long commercial runs. Keep connections dry and sealed.
Finish the install: antenna mounts · fixed-mount VHF radios · VHF antenna guide
Before ordering
Confirm the required mount, coax and connector arrangement, installation clearance, and whether a 4-foot antenna gives the range you need.
