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.

Transmit/Receive

Antenna Port

Receive Only

Antenna Port

Notes:

Antenna Port A is a transmit and receive port for use in all

applications.

Antenna Port B is a receive only port and is used for dual

diversity antennas applications only. This port is not used

for point to point applications.

Warnings:

Only pre-made coax cables from the factory used in

conjunction with either the AA20Eg omni-directional

and AA203Eg or AA204Eg directional antennas meet all

FCC Section 15.247(b) EIRP maximum power

requirements.

Use of the AA204Eg, directional antenna is limited to

fixed point to point applications only. In accordance

FCC Section 15.247(b)iii, this antenna must be

professionally installed. The installer must ensure the

system is used exclusively for fixed, point-to-point

applications and the ESTeem Model 195Eg is set for 0.25

Watts output power (Power Level = Min).

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.

CHAPTER 8 ANTENNA SETUPS ANTENNA AND CABLE CONFIGURATIONS (CABINET MOUNT) 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 cabinet mount configuration with the antennas listed below, and having a maximum gain of 7 dB in a multi-point system or 11dB in a point to point network with the authorized ESTeem coax cables.
PAGE 3
CHAPTER 8 ANTENNA SETUPS 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.

CHAPTER 8 ANTENNA SETUPS 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.

CHAPTER 8 ANTENNA SETUPS 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).

CHAPTER 8 ANTENNA SETUPS 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: 1. 2.

CHAPTER 8 ANTENNA SETUPS 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.
