Black RG58 coaxial cable with SMA male and female connectors, 20 meters long

PISKEKAT

PISKEKAT RG58 SMA Male to Female Coaxial Cable 20 m 50 Ohm game controller

SKU CH-5PZG-Q5A3P

A 20-metre RG58 coaxial cable with SMA male-to-female connectors and 50-ohm impedance for extending antenna connections

  • TypeOther
  • Double-layer shielding keeps signals clean over long runs
  • 20 metre length reaches distant antennas without splicing
  • 50 Ohm impedance matches standard RF equipment
  • RG58 construction handles higher frequencies than thinner cables
  • Extended 6 cm heat-shrink protects connectors from bending stress

RG58 SMA Extension Cable 20 m

This 20-metre RG58 coaxial cable carries a 50 Ohm impedance and terminates in SMA male to SMA female connectors. It is built for SMA-based equipment such as routers, SDR dongles, ADS-B receivers and amateur radio gear. The low-loss construction suits longer cable runs and higher-frequency use.

Double-Layer Shielding for Signal Retention

Copper braid plus aluminium mylar shielding reduces signal loss compared with single-layer RG58, RG316 or RG174 alternatives. The flexible jacket eases routing through tight spaces while maintaining performance. No thermal, noise or power-draw concerns apply to this passive coaxial assembly.

6 cm Heat-Shrink Strain Relief

Each connector end receives a 6 cm heat-shrink tube, longer than typical designs, with professionally crimped joints. This reinforcement prevents the SMA adapters from pulling loose when the cable is bent or tensioned. The package includes one 65.6-foot male-to-female adapter cable.

Questions about this item

How do I install the SMA Male to Female coaxial cable, and what step do people often get wrong?

Screw the SMA Male connector onto your device's SMA Female port and the SMA Female connector onto the antenna's SMA Male plug. The step people often get wrong is not tightening the connectors fully by hand, which can cause signal loss.

What maintenance or replacement will this 20 m RG58 cable need later?

Inspect the 6 cm heat-shrink tubing and double shielding for cracks or water ingress after prolonged outdoor use. Replace the cable if the braid or foil is damaged, as the solid crimped connections are not user-serviceable.

What limit shows up first under sustained use with this 50 Ohm extension cable?

Signal attenuation over the 20 m length at higher frequencies is the first limit. The RG58 construction has higher loss than thinner cables like RG174 or RG316, so extended runs may reduce gain for LTE, SDR or ADS-B receivers.
