SMHAP UAP-AC-MESH Manual
Rev. 07/19 (LBB0132)
3.2
Site Selection
The SMHAP must be mounted so that it has an un-obstructed view of the target area. The
SMHAP can obtain its power from any nearby power passing tap, splitter, or coupler. An
SMHAP with a UniFi AP can consume up to 23W of power.
3.3
Installation
Installation of the SMHAP is similar to the installation of a line extender, or tap, or other
piece of CATV equipment. Use the diagrams in this section as guide to the installation,
and the diagrams in section 2 to help locate the components referred to in the following
instructions.
1. Mount the SMHAP in its final location. If using hanger brackets, the existing strand
clamps should be left in place to act as spacer allowing the same bolts to be used (See
section 3.4).
2. Pull the AC interrupt at the upstream coupler.
3. Open the lid of the SMHAP, by undoing the 4 bolts using a 13 mm wrench.
4. Replace the two 0 dB RF pads with pad values that were determined before entering
the field.
5. Make a coaxial connection to your HFC network at the upstream coupler.
6. Mount and aim the antennas. All omni -directional antennas should be orientated
vertically (pointing downward). Sector antennas should be mounted so that the RF
connector is at the bottom.
7. Re-install the AC interrupt. Indicator LEDS on the cable modem and radio should
indicate startup and discovery of their respective networks. (Refer to the cable modem
installation guide for more information.)
8. The forward and reverse RF levels at the cable modem can be measured at the single
test point. Readings are -20dB relative to the cable modem F connector. Make
adjustments to pad values as required.
9. Silicone Grease can be applied to the exposed part of the o-ring before swinging the lid
back into place. This will reduce any tendency of the o-ring to stick to the lid and ensure a
weather-tight seal. To be clear, use Silicone Grease, not Silicone Sealant, nor any other
type of Grease.
10. If the EMI gasket has any frayed or loose ends tuck them back into the channel and
close the lid while ensuring that the wire harness does not interfere with the base and lid
sealing surfaces.
11. Using a torque wrench with a 13 mm socket, tighten the lid bolts gradually and
alternate diagonally to avoid stress or warp on the housing sealing surfaces. The lid bolts
should be tightened to the specified 17-ft LB or 24 Nm torque to ensure that the EMI
specification is met. The required torque is easily met by using the box end of a
combination wrench, but cannot be reached using a nut driver.
