ASSEMBLY INSTRUCTIONS

SD30 Parabolic Grid Antenna
SD19, SD21, SD24, SD27 Assembly Drawing

At 135MPH, SD27 has a windage of 591 Newtons. This is equivalent in American usage to 133LBS., far lower than any competition. Note also that SD19 has been rotated in a wind tunnel at 191MPH without failure.

Please make enquiries about antenna requirements in the 1.5 - 6.0 GHz range.

BENEFITS

Parabolic Grid Antennas can be used for:

Point to point links
Point to multi-point links
CCTV
Data/telephony

Complies to ETSI EN 301 525 V1.1.1 (2000-03)TS3
These professional Antennas are outdoor weather sealed and tested gas-tight.
Lowest windage, and highest survival rate, in independent wind tunnel tests
Welded steel gives maximum strength/weight ratio
N-male type connectors - please enquire.
N-female / SMA adaptor available - please enquire
These Antennas can be tilted (standard pole mount brackets with optional tilt brackets)
Material-welded wire hot dip galvanised - no rust
Nesting, and fully stackable on the flat in the warehouse. Most compact for shipping.

FEATURES

Dimensions of wire-14G in mesh 12.5mm X 25mm
Method-press formed from flat panels for uniformity
Fully parabolic, not sectional

FASTENINGS AND DIPOLES

Brackets are made from hot dip galvanised steel.
Installation is made easier as wing nuts are used throughout.
Dipole boxes are made from ABS shock resistant plastic.
Each dipole is tested gas-tight.

The reflectors are fully parabolic, not sectional. 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 191MPH without damage or direction change. Also, unlike sectional reflectors, warping does not occur.
