Antenna Extension Cable SMA Male to SMA Male

This 1.5 ft RG58 coaxial cable connects two SMA female ports with male pin connectors on each end. It provides a 50 ohm impedance path for RF signals in wireless LAN devices, Wi-Fi radios and external antenna installations. The .2 inch diameter cable is built for low loss performance across typical RF applications.

Verify Connector Gender and Impedance Match

Confirm that both devices you intend to link present SMA female jacks with a 50 ohm characteristic impedance. The cable uses SMA male plugs with a centre pin, so it will not mate with RP-SMA or other reverse-polarity variants. Measure the required reach between mounting points to ensure the 1.5 ft length is sufficient without strain on the connectors.

Replaces Shorter or Higher-Loss RG58 Jumpers

Upgrade from a shorter factory lead or a lossier RG58 assembly when you need extra routing distance while keeping the same 50 ohm impedance and SMA interface. The jump is worth it if the existing cable limits antenna placement or shows measurable insertion loss at your operating frequencies. Builders who need a different connector type, a longer run or a different impedance should look elsewhere.

Questions about this item

Does the 1.5 ft RG58 cable arrive with both SMA Male connectors already fitted?

The package includes one RG58 coaxial cable with SMA Male connectors pre‑installed on both ends.

When should I choose the 1.5 ft length over a longer run?

At 1.5 ft the cable keeps insertion loss minimal for short antenna‑to‑radio links; longer runs add attenuation.

What does the 50 ohm rating mean for my Wi‑Fi radio setup?

A 50 ohm impedance matches most Wi‑Fi radios and external antennas, preventing signal reflections that degrade range.
