Key Features

  • IMPROVES SIGNAL STRENGTH and INTERNET SPEED on Verizon, AT&T, T-Mobile, Telus, Bell Canada, Rogers, DigiCel and all 4G LTE & 5G Sub-6 Cellular Broadband Services or use as a Wi-Fi Antenna (600 - 6000 MHz)

  • COMPATIBLE WITH Routers, Modems and Gateways from CalAmp, Cisco, Cradlepoint, Digi, MoFi, Netgear, InSeeGo, Pepwave, Proxicast, Sierra, ZTE and many others


  • STAINLESS STEEL 1.5" Diameter 2-Way Deck Mount Base with 1"-14 Marine Mount Adapter (marine mounts & coupler sold separately)

  • INTEGRATED FEMALE N CONNECTOR - No Additional Ground Plane Required
    USE AS a Marine WiFi Signal Booster to Reach the Marina's Network or as an Omnidirectional 5G Boat Antenna to Boost Internet Speeds on the Water

  • MUST BE CONNECTED VIA 50 OHM COAXIAL CABLE TO AN EXISTING CELLULAR or WI-FI MODEM/ROUTER/RADIO DEVICE. Does not improve signal for cell phones or other devices not directly wired to the antenna


Proxicast's small, light-weight, easy-to-install permanent mount omni-directional antenna improves transmit and receive signals for all 4G/LTE and sub-6 GHz 5G frequencies on Verizon, AT&T, T-Mobile, US Cellular, Bell Mobility, Rogers, Telus, Sasktel, Telcel, Movistar, Digicel and many other cellular operators worldwide.

The highly efficient omni-directional radiator design provides high gain without the cellular tower location and alignment hassles of directional antennas. It can also be used as an antenna for 900 MHz and 2.4/5.8 GHz unlicensed radio systems such as Wi-Fi.

Its compact size and white or black finish and the included all stainless-steel mounting bracket and U-bolts, nickel-plated N connector and ABS radome resist corrosion making this antenna perfect for outdoor or marine applications. Pole/Wall and Standard 1"-14 Marine Mount options are possible with optional mounting hardware.

With the appropriate adapter cable (not included), this antenna is compatible with 4G/5G cellular modems, routers, gateways, hotspots and signal amplifiers from companies such as CalAmp, Cisco, Cradlepoint, Digi, MoFi, Netgear, Inseego, Pepwave, Proxicast, Sierra Wireles and ZTE.

For MIMO applications use 2 identical antennas spaced approximately 2 ft apart horizontally.

WILL NOT boost reception of cell phones – they require a powered booster/amplifier.

Marine Mount


  • Proxicast's Pro-Gain Omni Bullet antenna sends and receives signal in all directions unlike directional 4G/5G & WiFi panel & yagi antennas that require time-consuming effort to position
  • High Gain allows cellular modems & routers to pull in more signal for greater throughput
  • The foam filled rugged housing and heavy duty stainless steel mounting hardware are ideal for marine use

Pro Tips

For Best Results

  • Orient antenna vertically
  • Mount antenna as high as possible, but keep coax lead as short as possible
  • Position away from other antennas, lighting fixtures, motors, Low-E or tinted/coated windows, large metal or concrete objects
  • Do not use a Y-cable to connect 2 modem ports to one antenna - use 2 antennas
  • Do not use RG59/RG6 coax (75 Ohm TV cable from the hardware store) – signal will be seriously degraded.  Use low-loss 50 Ohm coax designed for cellular use: ANT-140-020
  • Weatherseal outdoor connections. Use Silicone Tape part# ANT-900-002
  • Stand 3+ feet away from antenna when testing
  • Maximize signal Quality(SINR, RSRQ) not signal Strength(RSSI, RSRP, bars)
