Signal Extension Cable

This Maswell Communication Tech. LMR240 equivalent coaxial cable extends SMA connections by five metres. It serves installers and hobbyists who need to link 50 Ohm antennas to routers, modems, SDR receivers or amateur radio gear without moving the host device. The SMA male-to-female layout lets you bridge existing runs or reach outdoor mounts while keeping the signal path intact.

Low-Loss Construction

Foamed PE dielectric and a solid copper centre conductor keep attenuation low across 3G, 4G, 5G, LTE, Wi-Fi and ADS-B bands. Aluminium foil plus tinned copper braid shields the signal from external noise, and gold-plated brass pins on both connectors resist oxidation for stable contact. The black PVC jacket protects the assembly during indoor or outdoor routing.

Sustained RF Performance

Shielding effectiveness and dielectric stability remain consistent during continuous transmission, so long-term links such as permanent antenna installations or always-on SDR monitoring do not suffer rising loss. The cable handles the power levels typical of the listed applications without heating or degradation. It is not suited for runs that demand a larger LMR diameter or for frequencies far above the common cellular and Wi-Fi ranges.

Questions about this item

How do I install the SMA male-to-female connectors on the LMR240 cable, and which step is most often done incorrectly?

Screw the SMA male end onto the device port clockwise until finger-tight, then give a light spanner turn; the common error is over-tightening, which can crush the foamed PE dielectric and raise loss.

What maintenance or replacement will the LMR240 cable need over time?

Inspect the PVC jacket for UV cracking and check the gold-plated brass pins for corrosion; replace the assembly if the braid shield is kinked or the dielectric feels soft.

What limit appears first on the LMR240 cable during sustained high-power use?

The foamed PE dielectric and PVC jacket set the thermal ceiling; continuous power above the cable's rated handling will soften the dielectric before the copper or braid degrades.
