Antenna Installation
1. Assembling2. Installation
1. Assembling
1. Unpack the antenna from the cartoon using knife carefully.
2. Verify it according the RF plan.3. Using D-type 12-13 no spanner assemble it.
2. Installation
1. Connect O/D jumper to the antenna port using 30-32 D-type spanner.
2. Do the weather proofing on Jumper-Antenna connection (only PVC tape).
