ASSEMBLING THE AA195PM TWO HOLE OUTDOOR POLE MOUNTING KIT
The AA195PM mounting kit contains everything required for pole mounting and weatherproofing the ESTeem Model 195E for
outdoor installations. The 195E with AA195PM mounting kit can be directly mounted to a round pole from 1.25” to a diameter of
2.25” OD. Any mounting structure greater than 2” requires hose clamp strapping run through the Pole Mount Brackets. The
mounting kit requires the following assembly:
1. If you purchased an AA195PM mounting kit with your Model 195E, the kit will be packed in the same packing box as the
ESTeem (Figure 1).
2. Remove and inventory the two (2) Pole Mounting Brackets, one (1) Two-Hole Face Plate Cover (with single port cover
installed), one (1) Heat Shield and (1) AA195PM Hardware bag from the packing box (Figure 1). Report any missing or
damaged items to ESTeem Customer Support (509-735-9092 Phone) as soon as possible for replacement.

3. Inventory the AA195PM Hardware bag for all the components listed in Figure 2.
4. Assemble the two Pole Mounting Brackets with the included U-bolts, hardware and Pole Mount Clamps. Reference Figure 3.
5. Place the four supplied 10-24 x 1” Phillips Pan Head screws through the mounting holes of the Heat Shield and attach to the to
the top of the ESTeem 195E (Figure 4).

6. Attach the two Pole Mounting Brackets to the ESTeem Model 195E with the 10-24 x 1” Phillips Pan Head screws through the
top of the heat shield. Reference Figure 5 (Heat Shield removed for detail).
7. Assemble the outdoor rated CAT-5e Ethernet cable (Not Provided) with the supplied Ethernet Cable Boot (Figure 6).
8. Feed the CAT-5e Ethernet connector(s) through the Face Plate Cover and secure the Ethernet Cable Boot to the cover.
Reference Figure 7. NOTE: The Ethernet cable boot must be installed before the RJ-45 end is installed. If using the ESTeem
AA09.1 outdoor Ethernet cable, verify that the Ethernet cable boot end is routed toward the ESTeem 195E.

9. Route the CAT-5e Ethernet cable through the molded strain-relief fins in the Face Plate Cover (Figure 8) to secure the cable
and provide strain-relief for the connector. If a second Ethernet cable is installed, remove the second port cover and route
cable.
10. Plug the CAT-5e Ethernet cable to the Model 195E’s Ethernet port and secure the Face Plate Cover with the attached thumb
screw. Verify that the weatherproof seal on the Face Plate Cover is sealed against the outer rim of the Model 195E. Reference
Figure 9.
11. Attach the antenna connector boots as show in Figure 10 for either dual attached antennas or external antennas. You are now
ready to mount the ESTeem Model 195E

195E POLE MOUNT GROUNDING PROCEEDURES
Mounting the 195E series radio modem outdoors requires proper grounding procedures to prevent damage to both the radio
hardware and the connected Ethernet and Serial peripherals. The case on the 195E series wireless modem is electrically
conductive, but the AA195 Pole Mount kit provides isolation from the connected structure. To bring the 195E case to a ground
potential with Earth ground and eliminate any static buildup on the case itself, the shield on the Ethernet cable is used to provide the
ground connection.
Outdoor Ethernet Cable
A critical component of this grounding protection system is the ESTeem AA09.1 outdoor, shielded CAT-5E Ethernet cable. This
cable provides three, necessary elements; Ethernet data, DC Power over Ethernet (PoE) applications, and a ground from the 195E
case to the AA166 surge protector. The Ethernet cable is outdoor rated and protected from UV breakdown.
Installation
The following diagram outlines all the critical components and connections in the 195E series system. The Earth ground
connection to the surge protector must be installed to comply with local Electrical code requirements.

FRESNEL ZONE
The Fresnel zone shows the ellipsoid spread of the radio waves around the visual line-of-sight after they leave the antenna (see
figure above). This area must be clear of obstructions or the signal strength will be reduced due to signal blockage. Typically,
20% Fresnel Zone blockage introduces little signal loss to the link. Beyond 40% blockage, signal loss will become significant.
This calculation is based on a flat earth. It does not take into account the curvature of the earth. It is recommended for RF path
links greater than 7 miles to have a microwave path analysis done that takes the curvature of the earth and the topography of the
terrain into account.
Fresnel Zone Radius = 72.1 SQRT [(d1d2) / (F(d1 + d2)]
