1. Introduction of Epoch-H
1.1 Introduction
Epoch-H series repeaters enhance outdoor wireless coverage in the most effective
and cost efficient way. For its intelligent design and versatility, Epoch-H series
repeaters are the ideal choice for wireless coverage problems outdoors.
In many large scale in-building applications, Epoch-H series repeaters can also be
used (e.g. malls, campuses, stadiums, etc.) with passive antennas instead of a
DAS (distributed antenna system) and offer significant cost savings.
**Using ADRF’s ‘High Isolation Antennas’, will allow for enhanced performance
by creating higher isolation. Please contact ADRF Sales for more information.

Epoch-H has three LEDs on the Inner Control Board panel of the repeater as
shown below in Figure 7.
Figure 7 – Epoch-H Repeater LED View
POWER
If the LED is lit GREEN, it indicates that there is AC power to the repeater.
SOFT FAIL
If the LED is lit YELLOW, it indicates that there is a soft fail alarm in the
system. The detailed alarm information can be viewed via the local User GUI.
In the event of a soft fail alarm, the repeater will still function, but the alarm
needs to be addressed promptly.
HARD FAIL
If the LED is lit RED, it indicates that there is a hard fail alarm in the system.
The detailed alarm information can be viewed via the local Web GUI. In the
event of a hard fail alarm, the repeater will not function and immediate
attention is required.

2.2 Installation
2.2.1 Tools
No special tools or equipments are needed to install the Epoch-H
2.2.2 Procedure
Eight mounting holes are located on the wall-mounting bracket to attach it to
the wall. The wall bracket must be securely attached to sufficiently carry the
weight of the Epoch-H, which is bolted to the wall bracket through the four
aligned mounting holes.
The following steps should be followed while mounting the repeater:
Installation Procedure
① Take the Epoch-H out of the box
② Using the six anchor bolts, mount the bracket on the wall
③ Make sure the bracket is securely mounted
④ Slightly tilt the repeater and mount the repeater onto the wall as shown in
the picture. Hook the upper 2 guard screws first and then slide/push in
the lower 2 guard screws into place.
⑤ Make sure the Epoch-H is securely placed onto the wall bracket
⑥ Fasten the 8 bracket screws back properly
⑦ Inspect that everything is secure

2.2.3 Grounding
A ground cable is included in the packaging and should be properly connected
to the repeater as shown below.
Figure 13 – Ground Cable Connection
Advanced RF Technologies, Inc. Proprietary Document Page 20 of 60
Epoch-H (HP/HC) RF Repeater
User Manual V1.5
2.3 Antenna Separation/Isolation
Separation between antennas is necessary to prevent oscillation.
Oscillation occurs when the signal entering the system continually reenters, due to the lack of separation between the donor and server antennas.
In other words, the signal is being fed back into the system. This creates a
constant amplification of the same signal. As a result, the noise level rises
above the signal level.
Figure 14 - RF Repeater Oscillation
To prevent feedback, the donor and server antennas must be separated by
an appropriate distance to provide sufficient isolation. Isolation is attained
by separating antennas a sufficient distance so that the output of one
antenna does not reach the input of the other. This distance is dependent
on the gain of the repeater.
A sufficient isolation value is 13 ~ 15 dB greater than the maximum gain
of the repeater. For example, if the gain of the repeater is 50 dB, then an
isolation of 63 ~ 65 dB or greater is required. In the same manner,
because the Epoch-H has a maximum gain of 95 dB, it requires an
isolation of at least 108 ~ 110 dB.
Advanced RF Technologies, Inc. Proprietary Document Page 21 of 60
Epoch-H (HP/HC) RF Repeater
User Manual V1.5
2.4 Line of Sight
The donor antenna which points towards the base station typically has a
narrow beam antenna pattern. As a result, a slight deviation away from
the direction of the BTS can lead to less than optimum results. In addition,
obstacles between the repeater and the BTS may impair the repeater from
obtaining any BTS signal. As a result, the repeater cannot transmit signal
to the coverage area. Therefore, a direct line of sight to the BTS for the
donor antenna is vital to the function of a repeater. For the same reason,
placing the server antenna in direct line of sight of the coverage area is
also necessary.

model). The functionality of the AGC feature is assured under the condition that
the input BTS signal is within the specified AGC range and that sufficient
isolation exists between antennas. By default, the AGC ON box is checked. To
manually change the gains in both the links, AGC ON must be unchecked.

connections are loose, make sure that all connections are tightly fastened
properly.
4.1.2 Cables and connectors are in good condition.
4.1.3 Ensure that the repeater brackets are in good condition and that the repeater
is securely fastened.
4.2 Preventive Measures for Optimal Operation
4.2.1 Recommendations
Perform the Periodic Inspection Checklist quarterly or semiannually.

5.1 Connectivity Guide for LAN
∴ If you cannot connect to the Web GUI, please follow the steps listed below:
i) If you see the icon below (Figure 16)
Figure-16
- Check the Power Line to see whether or not the repeater is being powered correctly.
- Use the Cross-over Cable that came with the repeater to connect the repeater to your
laptop. If you still cannot connect, replace the cross-over cable with another one.
- If unsuccessful, power the repeater down and wait for at least 5-10 seconds for it to
electrically discharge, then power the repeater back up. Wait for the PWR LED to light
up before attempting the IP address in browser again. (When the repeater powers up, you
will hear a faint click)
ii) If you see the icon in Figure 17, then the computer is in the process of
obtaining an IP Address and you will not be able to connect to the unit. Once you see the
icon in Figure 18 then you can attempt to connect to the unit.

5.2 Troubleshooting Guide for Repeater
Alarm Status Parameter Troubleshooting
1. Make sure connectors are tight at each port.
Sweep lines.
2. Use a 50 Ω dummy load, connect it to the
Alarming Port to check whether the repeater
is faulty. (e.g. if the Down Link is alarming,
VSWR Hard Fail VSWR Over 3:1
Epoch-H(5Watt) 37dBm~38dBm
connect the dummy to the Server Port.)
3. If multiple Server Antennas are connected,
connect only one antenna and recheck the
Alarm. If the Alarm clears, faulty connectors
like combiners/ splitters in the serving line and
lightning arrestors (polyphasers) may be
causing the problem.

1. Check Input Level. (fluctuates drastically)
2. We recommend 13~15dB + max gain of
repeater between the donor and the server
antenna as an isolation value.
Low Isolation
Oscillation
Antennas are located too close to one another, causing RF output to feed
input.
3. Check antenna direction (make sure that the
Donor and Server antennas are not facing
one another)
4. Placing an attenuator before the nearest
serving antenna can also help to increase
isolation.

Connectivity Issue Unable to Interface to repeater with GUI Software.
User Manual V1.5
1. Please verify under ‘Device Manager’ of
Windows that the necessary drivers for the USB
to serial adapter are installed.
2. Be sure to use the GUI software from the CD
that came with the repeater.
3. If for some reason the CD is not available,
contact 24HR tech support to acquire the
appropriate one.
4. In the event of using a USB-to-serial
converter, you must be sure to the ‘COM port’
number on the ‘STATUS PAGE’ matches the
COM port number of the usb to- serial adapter
in your ‘Device Manager’ of Windows.
5. If the GUI software at any time reports a
missing file error such as “component
missing”, please be sure to contact our tech
support staff directly at the number provided
below.
6. Connectivity is accomplished successfully
when both TX/RX lights are blinking green
in the lower right-hand corner of the GUI
software.
To get output power on the Downlink side o f
the BDA even lower to plug into a DAS system,
the use of 5dB or 10dB attenuators/pads with
the proper tolerance of wattage is
recommended.
Connecting to DAS
All our PCS as well as Cellular BDAs can have the ‘AGC’ function enabled
and the ‘Downlink AGC Level’ set from 0dBm to whichever value is
specified by the manufacturer for common DAS applications.
PCS: lowest DL AGC value 0dBm
