The WR-AX-400D is a parabolic sector-divided dish, constructed from six solid powder-coated steel panels. Three supporting legs anchored to the dish perimeter provide a prime focussed mounting point for a LNB or feeder.

The feeder mounting bracket is made from 5 mm thick mild steel and provides three 4.2 mm holes to mount the LNB or feeder using M4 screws. These holes are located in a circular configuration on a 52 mm radius, spaced apart equally at 120. Additional holes can be drilled by the installer, if so required.

The dish has a 120 cm aperture and focal length of 45 cm, giving it an f/D ratio of 0.375. It may be used in different frequency bands, with gain varying from 24 dBi in the L-Band to 40 dBi in the Ku-Band.

The dish kit includes all brackets, bolts and nuts required to facilitate mounting onto two 65 x 35 mm rectangular hollow steel tubes (not included), as well as clips to secure coax cable of size RG58 to the dish.

The dish is easy to assemble and is shipped in kit form with a comprehensive step-by-step illustrative manual.

The WR-AX-400D dish forms a well-engineered and fully-integrated combination with the WR-AX-G400-PF patch feeder. If used together, the antenna system will have an overall gain of 24 dBi, with a -3 dB main lobe beamwidth of 11, while the side lobes are at least 25 dB below the main lobe.
