Statistical analysis of WSPR reports over a two month period indicate that the actual relative gain patterns between antennas 1 and 2 correspond to the modelled gain patterns. The antenna model and simulation results were obtained using the Altair Feko antenna modelling software. Included in the model is the wooden tower and attached structure. The attached structure is a 10-12 foot wooden shed that houses the remote antenna tuner. The wooden tower has minimal effect on various antenna gain patterns, but it does have a notable effect on the each antenna's resonance. Resonance is lowered.

Antenna system now has 32-10 meter radials buried about 2 inches below the surface.

Just upgraded the tall vertical from 11 Meters to 14 Meters. Currently operating with 8-4.5 Meter radials and 8-10M radials.

Next improvement will be to extend the 4.5 Meter radials to 10 meters, for a total of 16 10 Meter radials.
