PRIME FOCUS PARABOLIC GRID ANTENNAS
These are professionally made, economically priced
antennas. This design has the highest strength / weight
ratio. Wind tunnel tests prove that they will stand
up to high winds. For instance, the model SD19 has
been rotated slowly in a wind tunnel with wind force
305km/h without damage or direction change.
- Welded steel gives maximum strength / weight ratio
- Lowest windage, and highest survival rate, in independent
wind tunnel tests
- Material-welded wire hot dip galvanised - no rust
- Dimensions of wire-14G in mesh 12.5mm X 25mm
- Method-press formed from flat panels for parabolic
integrity
Example Frequency Range 1900 - 2100MHz
