What AC Antennas does
AC Antennas A/S is a Danish designer and manufacturer of high-performance antennas for professional marine, land-based communication, security/surveillance, and OEM applications, headquartered in Glostrup near Copenhagen. Founded in 1970 as HMP Antennefabrik A/S and rebranded to its current name in 2014, the company produces a broad portfolio spanning VHF, HF/MF, UHF, AIS, NAVTEX, GNSS, WiFi, 4G/cellular, and air band antennas under its core brand and the CELmar sub-brand for recreational boating. All products are engineered and manufactured in Denmark using a proprietary crimping technology introduced in 2015, which produces gas-tight joints independently tested at DELTA to be 4-5 times mechanically stronger than traditional soldering, with every unit undergoing 100% functional and visual testing before shipment. Products carry IEC 60945, GOST, IACS E10, and RMRS marine certifications and are approved for operation from -55°C to +70°C.
The company sells exclusively through a B2B channel of 300+ professional distributors, integrators, dealers, and OEM manufacturers worldwide, with approximately half of sales generated outside Europe. Pricing is quote-based with high-running SKUs such as the CX4 VHF and KUM HF antennas available within 48 hours from large Danish inventory, and other products within 1-2 weeks. Revenue streams consist of core antenna sales, OEM/custom engineering for specific marine projects, and a complementary portfolio of RF cables and connectors. The company has been a subsidiary of ISIC A/S (and therefore Lagercrantz Group AB, listed on NASDAQ OMX Stockholm) since 2021, and is currently expanding into North America via a newly formed wholly owned subsidiary, AC Antennas Inc, operating warehouses in Texas and New Jersey to localize support for the region's integrators.

AC Antennas competitors and assessment
Company assessmentEmerging players
- Taoglas: Specialist in advanced IoT, GNSS, and 4G/5G antenna solutions for industrial, automotive, and smart city applications. Competes directly with AC Antennas' 4GMultiband and CEL24 WiFi products in the land-based cellular/WiFi/security segment.
Broad incumbents
- HUBER+SUHNER: Swiss manufacturer of RF and fiber optic connectivity, including a dedicated marine and offshore antenna portfolio. Competes with AC Antennas on HF, VHF, and GNSS antennas for professional maritime customers and brings broader RF connector and cable capabilities.
- Furuno: Global marine electronics leader producing radars, navigation, sonar, and communication systems, and an AC Antennas channel partner. While Furuno does not specialize in antenna manufacturing, it is a strategic comparable as both buyer/competitor-adjacent and benchmark for the marine electronics ecosystem AC Antennas serves.
- PCTEL: US-listed provider of antennas and wireless test solutions for industrial IoT, public safety, defense, and GNSS markets. While broader than AC Antennas, it is a relevant comparable for the land-based cellular/4G and GNSS antenna segment where AC Antennas is expanding.
- Laird Connectivity: Broadline supplier of antennas, IoT components, and connectivity solutions serving industrial, automotive, and telematics markets. Overlaps with AC Antennas in cellular, WiFi, and GNSS antennas for industrial and security/surveillance applications, though it does not focus on professional marine.
Direct peers
- Comrod: Norwegian manufacturer of professional marine, military, and commercial antennas (VHF, HF, UHF) with strong presence in Nordic shipyards and offshore. Closely comparable to AC Antennas in product breadth, customer base (commercial vessels, naval, offshore), and B2B distribution model.
- Panorama Antennas: UK-based manufacturer of VHF, UHF, cellular, WiFi, and GNSS antennas serving marine, public safety, and industrial markets. Directly comparable in product range (especially land-based cellular/4G/multiband antennas competing with AC Antennas' 4GMultiband) and global distribution model.
- Shakespeare Marine (Shakespeare Electronics): Long-established US manufacturer of marine VHF, AIS, and HF antennas with comparable professional and recreational product lines (e.g., Phase III, Centennial). Directly competes in the same marine antenna category as AC Antennas' CX4 and CELmar ranges and serves similar OEM and distributor channels.
- Procom (a/s Prosol): Danish peer specializing in professional-grade antennas across VHF/UHF/HF and cellular bands for marine, land mobile radio, and industrial applications. Shares AC Antennas' Danish origin, B2B partner model, and emphasis on harsh-environment durability and certified quality.
Others
- ISIC A/S: Sister company within the Lagercrantz Group that produces marine monitors and PCs. While not an antenna competitor, it is a strategically related peer due to shared parent ownership, similar Danish manufacturing footprint, and joint customer base in marine electronics OEMs.
