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. Antennas not included in this list or having a gain
greater 7 dB in a multi-point system or 11dB in a point to point network with any other types or lengths of coax cable are
strictly prohibited for use with this device. The required antenna impedance is 50 ohms.
Part Number: AA20E

• Feedline minimums: 25 ft. RG-8 Cable or 50 ft. Heliax
Cable with AA228LMR and Lightning Arrestor (EST
P/N: AA165).
Part Number: AA203ES
•
••
• Directional Building Mount Antenna, 7 dBd gain
•
••
• Feedline minimums: 25 ft. RG-8 Cable or 50 ft. Heliax
Cable with AA228LMR and Lightning Arrestor (EST

• Point to point applications only. See Warning.
COAXIAL CABLES
A 25-ft. length of RG-8 coax cable or 50-ft. length of ½”Heliax cable are the minimum cable lengths allowed for use with the above
antennas (AA20E, AA203ES, AA204ES) when the Model 195Eg is set at Max Power. Listed below are representative cable losses
in db/100 ft at the 2.4 GHz frequency range:
Feedline Type
Attenuation
(dB/100 ft.) @ 2.4 GHz
Additional RF Losses Attenuation (dB)
RG-8 (Solid) 7 AA228LMR (2.5’ TNC-MRP/N-
MRP) Jumper Cable
0.9
LMR 600 4.4 AA165 Lightning Arrestor 0.1
3/8" Heliax 6.5 All Coax Connector Terminations
(2 for every coax cable)
0.2
1/2" Heliax 3.5
7/8" Heliax 2
1.25" Heliax 1.6
In a severe noise environment it may be necessary to use a double shield type of coax cable such as RG-214/U in place of the RG-8.
This cable must be purchased from the factory to meet FCC requirements.
Warning:
Only pre-made coax cable systems (Cable, Lightning
Arrestor and AA228LMR jumper cable) from the factory
used in conjunction with either the AA20E omni-
directional and AA203ES or AA204ES directional
antennas meet all FCC Section 15.247(b) EIRP
maximum power requirements.
Use of the AA204ES, directional antenna is limited to
fixed point to point applications only. In accordance
FCC Section 15.247(b)iii, the operator or installer is
responsible for ensuring the systems is used exclusively
for fixed, point-to-point applications.
