CHAPTER 8
ANTENNA SETUPS
ANTENNA AND CABLE CONFIGURATIONS (POLE MOUNT)
EST offers different types of antennas for both indoor and outdoor configurations. To reduce potential radio interference to other
users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than
that permitted for successful communication.
Warning: Only the tested cable lengths and antennas provided by EST meet the FCC maximum peak output power
requirements. Any other combination of antennas or coax cables is not authorized. This device has been designed to operate in
a pole mount configuration with the antennas listed below, and having a maximum gain of 6 dB in a multi-point system or
19dB in a point to point network. Antennas not included in this list or having a gain greater 6 dB in a multi-point system or
19dB in a point to point network are strictly prohibited for use with this device. The required antenna impedance is 50 ohms.

Note:
A -3 dB loss means you have lost 1/2 of your signal or transmitter power. A +3 dB gain means you have doubled (x2)
your signal or transmitter power.
Example:
A 6 dB antenna will increase the radiated output power of a 1 watt transmitter to 4 watts {times 4 = 3 dB (x2) + 3 dB
(x2)} and increase the received signal strength to receiver times 4.
WEATHER PROOFING COAX CONNECTIONS
1.
Coat the threads of the connectors with silicone lubricant prior to assembly (See Note 1) and hand tighten. Care should be
taken not to get any lubricant on the center conductor.
2.
Wrap the connector assembly with a vapor barrier patch for weather proofing (See Note 2), ensuring to overlap onto the coax
cable approximately 1 1/2 inches.
3.
Apply an electrical coating (sealing agent) over the vapor barrier patch for added protection (See Note 3).

ANTENNA DIVERSITY
The dual diversity antenna configuration on the ESTeem Model 195Eg allows the radio to operate more efficiently in areas with
high reflections (such as indoors or in a city) and without direct line of sight (LOS) between the antennas. One of the most difficult
conditions to control in a radio system is the effect of a destructive reflected radio signal called mutipathing. Multipathing occurs
when waves emitted by the transmitter travel along a different path and interfere destructively with waves traveling on a direct lineof-site path. The phenomenon occurs because waves traveling along different paths may be completely out of phase when they
reach the antenna, thereby canceling each other out. The dual diversity antenna configuration places a physical distance between the
antennas where one reflected signal will be out of phase, but the second will be not. The ESTeem Model 195Eg will sample both
antennas and select the best receive signal.
ANTENNA PORT SELECTION
The antenna ports on the Model 195Eg must be configured for either a single receive antenna (external mount antennas) or dual
diversity antenna setup. To access the port configuration open ESTeem Web page using your computer’s Web Browser as per
instructions in Chapter 4. Select Advanced from the menu items and Radio Settings-wlan0 device (Figure 1).

Press the next button and Figure 2 will be displayed. The receive antenna is configured by selecting the
wlan0_dot11CurrentRXAntenna drop down (Figure 2) and selecting the receive antenna. A value of 0 = Dual diversity (Both
antenna Ports A & B will be used to receive). A value of 1 = Single receive source (Antenna Port A only).

ASSEMBLING THE AA195PM TWO HOLE OUTDOOR POLE MOUNTING KIT
The AA195PM mounting kit contains everything required for pole mounting and weatherproofing the ESTeem Model 195Eg for
outdoor installations. The 195Eg 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:

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.
