Cable adapter H155 5 m FME socket to N male antenna connector, no brand

Coaxial adapter cable H155, 5 m long, with an FME female (socket) connector on one end and an N male (plug) connector on the other. Designed for RF signal transmission in LTE and other wireless systems that use H155 (mini-UHF-like) coaxial cable. This cable is intended for extending or adapting antenna installations and for connecting external antennas to routers, modems or signal boosters where one device requires an FME socket and the other an N male connector.

Advantages

The 5 m length offers flexibility when positioning external antennas and communication equipment without introducing unnecessary loss from overly long runs. The use of H155 coaxial type provides a compact diameter suitable for tight routing while maintaining adequate shielding for typical LTE and wireless applications. Having an FME female to N male configuration enables direct connection between devices with these common RF interfaces, avoiding additional adapters and potential signal degradation from extra junctions.

Suitable for

• Extending or adapting antenna cables between routers, modems, repeaters and external antennas
• Outdoor or indoor antenna installations where a short to medium cable run is needed
• Connecting signal boosters or GSM/LTE amplifiers to external antennas with differing connector types
• Temporary or test setups where quick conversion between FME socket and N male is required

Key specifications

• Cable type: H155 coaxial (mini-UHF-like)
• Length: 5 metres
• Connector A: FME female (socket)
• Connector B: N male (plug)
• Intended use: RF signal transmission for LTE and other wireless systems
• Typical applications: antenna extension, connector adaptation between equipment

How to use

Identify the device or antenna with the FME female interface and the device requiring an N male connection. Attach the FME female end to the corresponding FME male part on the antenna or cable and securely screw the N male plug into the N female socket on the router, modem, signal booster or antenna port. Route the cable to avoid sharp bends and excessive compression; maintain gentle curves to preserve the coaxial characteristic impedance. For outdoor runs, secure the cable along mounting points and use appropriate weatherproofing at exposed connectors if necessary.

Usage recommendations

To minimise signal loss and interference, keep the 5 m H155 cable run as direct as practical, avoid coiling the cable tightly, and protect connectors from moisture when used outdoors. Where lower insertion loss or higher shielding is required, consider using thicker coaxial types for longer runs or additional surge protection in lightning-prone areas.
