ham radio counterpoise 9 band - better earth/ less rfi
The G0PNR 9 Band Counterpoise is a simple but effective way to improve your RF Earth System on all of the HF Bands, especially if your shack is not at ground level.
Running long lengths of earth wire down the house, however thick, can often be ineffective, especially if the wire is around quarter wavelength, where the inductive impedance is high and therefore creates little or no earth.
Like a vertical antenna ground plane, the Counterpoise effectively lifts an earth condition up to your shack. Like an antenna ground plane though, the Counterpoise elements have to be a specific length, depending on the band you are working.
Each band has two wire elements, not just one and there is no multiplication of harmonically related bands, i.e. no elements doing more than one band. Fewer elements would work, but not as well.
Each wire element is cut slightly longer than standard, with the correct length clearly marked. This allows for trimming and fine tuning if desired.
This version connects direct to your existing RF Earth System in your shack. If this is not suitable, another version is available with a 4m length of 25mm earth cable and a 1m earth rod.
Other Counterpoise versions with less bands are also available. Check out the G0PNR Shop.
