Omnidirectional 5G / 4G LTE 600–4200 MHz Up to 12 dBi IP66 • Marine-grade
SeaCell SC-555 | Multi-band 4G/5G Omni Antenna
The SeaCell SC-555 is a multi-band omni antenna for 5G/4Gnetworks, covers 600–4200 MHz and reliably boosts range, signal strength and data rate, with a gain of up to 12 dBi. Thanks to its omnidirectional pattern, no alignment is required — installation is quick and simple.
Constructed from fiberglass, IP66, resistant to seawater and vibration — suitable for marine and outdoor use in demanding conditions.
Package: includes 1× LMR240 cable, 5 m with a SMA male connector (other lengths available on request).
Omnidirectional reception/transmission
Ideal when there are many towers around you or you change direction.
Multi-band 600-4200 MHz
Full compatibility with common 4G & 5G bands.
Up to 12 dBi
Higher SNR → better stability & uplink/downlink speeds.
IP66 • Marine-grade
Fibreglass body, resistant to seawater & extreme weather conditions.
LMR240 cable, 5 m
Approximately 0.5 dB/m loss @ 2 GHz — other lengths also available.
Type: Omnidirectional (Omni) external
Frequencies: 600–4200 MHz
Gain: up to 12 dBi (band-dependent)
Protection: IP66, UV/salt resistant
Material: Fiberglass
Cable: LMR240 5 m (SMA male)
Omnidirectional vs. Directional — Which should I choose?
Omni (Omnidirectional)
- Receives/transmits from all directions
- Ideal with many towers around you
- Useful for indoor coverage in an urban environment
- Usually lower gain (2-8 dBi)
Directional
- Targets one tower for maximum signal
- Better for long distances/obstacles
- Higher gain (9-20 dBi)
- Requires alignment
Tip: If your 4G/5G router supports MIMO (2x2 or 4x4), prefer two antennas (or a dual MIMO antenna) for even better performance.
