RG58 SMA Male to Female Extension Cable – 5mm Thickened 50 Ohm Coaxial RF Cable
Thicker Cable Construction for Reliable Antenna Connections
This RG58 SMA Male to Female Extension Cable is designed to extend the connection between compatible antennas and RF communication equipment.
Unlike thinner RG174 coaxial cables, which typically have an outer diameter of approximately 2.8mm, our RG58/U cable features a thicker approximately 5mm outer diameter. Its robust construction provides greater physical durability and typically lower signal attenuation than RG174 cable of the same length and operating frequency.
Key Features
5mm Thickened RG58 Cable
Manufactured using RG58/U 50 Ohm coaxial cable with a durable black outer jacket. The thicker cable construction provides improved mechanical strength compared with standard thin RG174 cables.
