Sigma Artificial Ground Plane Kit with 5m RG-58U & PL-259

An artificial ground plane, allowing you to mount an
aerial where you cannot get a normal metal-to-metal connection for the earth.

The ground plain can be used on boats, vehicles, houses, portacabins,
wheelchairs, bicycles, motorbikes, backpacks and more.

It has
the added advantage of isolating the aerial system from the vehicle, helping to
get rid of some interference (i.e. in modern tractors etc)


  • On a bracket fixed to the
    standard roof bars of Discovery, Freelander, Frontera etc
  • Through the roof of Land
    Rovers – no need to protect your earth connection from oxidisation
  • Fibreglass/GRP cabs on

  • Anywhere that a conventional
    earth connection is not easy to make

standard CB cable plug on the bottom.

This unit simulates a
connection to ground, so you do not have to worry about your metal to metal
earthing. This will cure any SWR problems which are down to poor earthing, but
if an aerial is in the wrong place, i.e. too close to metal around it, the EGP
will not help.

Also a good way of helping to
reduce interference as it allows the aerial to be completely isolated from the
