mANT30 Polarization Slant Guide
2. Remove MikroTIK Radio unit
Loosen the Wing Nut and remove the MikroTIK Radio with Case Holder
as shown in Figure 2.
*The preview is valid if a MikroTIK RB900 series radio device (sold separately) is installed.
Horizontal/Vertical polarization* +45°/-45° polarization*
0. Items Required
• 8mm, 10mm Wrench • This guide is written to be used with a MikroTik RB900
series outdoor device (sold separately) • mANT30 must be detached from pole •
1. Disconnect RF cables
Remove the MikroTIK Radio cover. Disconnect RF cables.
Use 8mm wrench to loosen the RF cables.
FIG. 1
This guide is written to slant mANT30 PA* Horizontal/Vertical polarization layout to +45°/-45°.
Slant can positively** affect Point-to-Point link:
1) reduce RF interference in signal congested areas;
2) reduce the impact on local microwave devices;
3) unify the channel output if deployed near a body of water.
* The polarization slant support mANT30 antennas with 8x square-bore parabolic dish. The guide assumes the mANT30 is preassembled.
** The upgrade is optional. Customer shall decide if polarization slant is useful of being applied. Slant must be applied to both antennas in Point-to-Point link.

4. Slant polarizations
Slant polarizations from Horizontal/Vertical to +45°/-45° by rotating the
Parabolic Dish and Feed 45° counter clockwise relatively to antenna
mounting brackets as shown in Figure 4.
3. Separate Parabolic Dish and Feed
Separate Parabolic Dish and Antenna Feed from assembly by unscrewing
M6 Nut x 8 pcs.
Remove all fasteners:
M6x20 Bolt x 8 pcs;
M6 Washer x 8 pcs;
M6 Spring Lock Washer x 8 pcs;
M6 Nut x 8 pcs.
Warning:
• Ensure the components are not damaged during the process.

5. Reassemble antenna components
Reverse guide steps #3 and #2
Install Back Plate to Parabolic Dish using:
M6x20 Bolt x 8 pcs;
M6 Washer x 8 pcs;
M6 Spring Lock Washer x 8 pcs;
M6 Nut x 8 pcs.
Attach Case Holder - MikroTIK Radio assembly to Back Plate by tting
Case Holder’s hinges into the Back Plate’s ange - see Figure 5.
Secure Case Holder using:
M4 Wing Nut x 1 pc.
6. Install RF cables
RF cable install instruction is shown in Figure 6.1
Connect +45° polarization to CH1, -45° polarization to CH0.
Invert the channel polarization on paired device:
Connect +45° polarization to CH0, -45° polarization to CH1.
Fit back the MikroTIK Radio cover.
Important:
• RF Cables connector tightening torque must be approximately 0.5 Nm.
