ICOM AT-140 / AT-141 tuner upgrade

Upgrade your ICOM HF/SSB radio tuner to include;

  • 4x Murata 0.15uF 100VDC X7R internal DC blocking capacitors
  • 0.5 metre Ancor RG-8X marine grade coaxial cable
  • Shakespeare gold plated brass PL-259 (male) connector
  • Shakespeare gold plated brass PL-258 barrel connector

The internal DC blocking capacitors remove the need to insert a DC block in your copper strap to the ground plate. 

The upgrade also  permits inserting an Isolation Balun without the need for an additional cable.  If you choose not to install the isolation balun or want to remove it in the future, simply insert the PL-258 barrel connector.
