18. FittingWeatherProtectiontoUnusedPorts
1. Remove the two guidance screws
from the unused port.
2. Fasten the two screws in the prepared holes
on the weather protection plate for future use.
3. Make sure that the gasket is positioned
correctly in its groove on the unused port
4. Fasten the weather protection plate to
the unit

19. ConnectingtheRadioCabletotheRadio
Stretch and attach the butyl sealing compound
around the connector in order to protect it from
moisture and corrosion.
Wrap one layer of the included PVC tape in a spiral from the top of
the radio connector, around the butyl sealing compound, down to the
cable. Finish by wrapping one more layer back up to the top.
Remove the protective cover from N-Female
connector of radio & MDU6366 unit.
Connect 0.6mtr NM-NM jumper in-between radio &
MDU6366 unit.

20. Ports B
Antenna(HOP)Alignment
• Check the Green LED on the radio & remove by pulling out cover from measurement port of radio
• Connect voltmeter with standard test probes (2 mm diameter) to alignment ports B, select 20VDC range
• Disconnect either Vertical or Horizontal radio from both ends and perform HOP alignment procedures
till the desired RSL value achieved

21. Perform below procedure at Both Ends of antenna after achieving desired RSL
 Slightly loosen all six screws G mounted on OMT unit to allow it to rotate (+5 or -5
degree) in such a way that desired XPI level is achieved
Follow below instructions for XPI Optimization if desired XPI Level is not achieved post
antenna alignment
● a. Verify OMT Installation is vertical to the mount/horizontal to the Ground at both
ends.
● b. Turn on the transmitter connected to vertical polarization(Far-end).Keep all other radio
Tx off.
● c. Measure the voltage in the alignment port of the radio connected with horizontal
polarization (near-end)
● d. Minimize the received signal, by rotating the integration unit in the polarizations plane,
try to Make it upto-65 db
● e. Turn on the transmitter connected to Horizontal polarization(Far-end) with same Tx
power as Vertical polarization .Keep all other radio Tx off
Repeat above ( c, d & e)procedure at Near End keeping Tx Off procedure at Far End.
Please consult planning for interference rectification in cases SINR (Signal to Noise
interference ratio) is < 40 dB

22. 1. Dual Polarization antenna required for XPIC implementation
2. XPIC Technology transmit same frequency on both Polarization (V & H)
3. XPD (Cross Polar Discrimination). It is a measure on how well a cross polar antenna can discriminate between
polarizations, i.e. how much of the signal in one polarization that is leaking into the other polarization.
4. Measurement of Interference with dual polarized antenna is called XPI ((Cross polar interference)
5. XPI value should be =>27dB
6. XPI optimization (by OMT alignment) is performed to minimize the leakage between the two polarizations, this is, to
maximize the cross polarization isolation.
7. XPI Value is not dependent on Rx Link alignment.
8. XPI Value is dependent on installation Quality and frequency interference on the link.
9. Sprit Level to be used to check installation quality of OMT Unit and Antenna
10. OMT Unit should be horizontal to Ground and Pole Mount should be in vertical position to Ground
XPIC(CrossPolarizationInterferenceCancellation)Introduction

23. CheckPoints–GoodInstallation
1. All the nuts & bolts should be properly tight.
2. Equipment grounding connection are properly terminated.
3. Recommended rated MCB used for DC power connection.
4. Pole mount should be in vertical position and Antenna
Fixed horizontally to the pole mount (Check with spirit
level)
5. IPS properly fitted to the Antenna, Otherwise XPI value
can’t be met.
6. Rotation of IPS mounting should be cross checked before
fixing it in vertical position in XPIC installation.
