The YILIANDUO SMA Antenna Extension Cable is a 5m SMA male to SMA female extension designed to preserve radio and router signal quality through low-loss RG58 coaxial construction. Confident installers and radio hobbyists gain a more reliable link and stronger reception in awkward setups. Does the tougher build and reduced attenuation make it the sensible choice for a longer run?
⚡ At a Glance
- • Signal Loss: Lower attenuation than thinner RG316 or RG174 thanks to RG58 construction
- • Best for: Extending antenna reach for 4G/5G routers, ham radios and RF test gear
- • Not ideal for: Terrestrial TV aerials and television reception use
5m low-loss RG58 coaxial cable with SMA male to SMA female connectors and 50 ohm impedance. Reinforced shielding and lengthened heat-shrink tubes improve mechanical durability and signal retention.
Longer runs with less signal drop - with low-loss RG58 coaxial construction
Low-loss RG58 uses a bare copper inner conductor, 96-wire braid and aluminium foil outer conductor, plus PE insulation and a PVC sheath to keep attenuation down compared with thinner RG316 or RG174 cable. The specification maintains 50 ohm impedance for standard RF antenna systems.
Reduced attenuation preserves signal strength across a 5m extension, keeping reception and data links steadier for routers, modems and radios. Suitable when moving an antenna a short distance away from the radio or gateway without severe signal penalty.
Stronger connector joints - with extended 6cm heat-shrink reinforcement
Heat-shrink tubes at both ends are lengthened to 6cm and bonded around the SMA connectors, improving strain relief and resisting connector detachment caused by bending or pulling. Robust crimping and braid coverage complement the heat-shrink protection.
Connector integrity lasts longer under mobile and field conditions such as vehicle installs or frequent handling. Expect fewer intermittent contacts and a lower risk of connector failure during installation.
Wide compatibility across comms gear - with SMA male to SMA female and 50 ohm spec
SMA male to SMA female termination and a 50 ohm characteristic impedance match common cellular, RF test and ham radio equipment. Compatibility list includes 2G/3G/4G/5G routers, BaoFeng handhelds, Kenwood and Yaesu transceivers, RTL-SDR dongles and FPV controllers.
Works with a broad range of routers, modems, scanners and portable radios, making the cable useful for hobbyists, installers and IoT gateway setups. Avoid using for TV aerials as suitability is not indicated for terrestrial television.

❓ Frequently Asked Questions
Q: Can this cable be used with BaoFeng handheld radios?
A: Yes, compatibility listings include BaoFeng models such as UV-5R and similar handheld transceivers, so the SMA male to SMA female termination suits those radios when an external antenna is required.
Q: Is the cable suitable for connecting a TV aerial?
A: No. The listing explicitly states the cable is not for TV aerials or television use, so terrestrial TV connections should be avoided.
Q: How does RG58 compare with RG316 or RG174 for signal loss?
A: RG58 is described as having far less attenuation than thinner RG316 or RG174 due to a larger copper conductor and heavier braid, which helps preserve signal strength over the 5m run.
🏆 Our Verdict
Antenna installers and radio hobbyists who need a sturdy 5m extension with lower attenuation will find this cable well suited. Durable RG58 construction, extensive shielding and extended heat-shrink protection make it a reliable choice for routers, modems and portable radios. While not the cheapest option, the enhanced build and reduced signal loss make it a sensible long-term purchase for critical antenna runs.
