EC20
Extended Coverage Antenna Kit
INSTALLATION INSTRUCTIONS
The EC20 is a directional antenna, primarily designed for extended outdoor coverage during speed-team
operations. It enables team members wearing HME COMMUNICATOR®s to greet customers at a greater
distance from the building, with uninterrupted transmission and reception. It can also be used indoors, in
stores where coverage is exceptionally difficult with standard, base station antennas.
These instructions are for typical outdoor installation of the EC20, which requires walk testing the antenna
coverage area to determine the best location for the antenna, mounting the antenna on the building, running
the coaxial cable from the base station to the antenna, connecting the cable to the antenna, lightning
arrestor, antenna adaptor cable and base station. Installation of the EC20 should only be done by an
HME-authorized installer. The installation should take approximately 2 hours.

1. INSTALLATION
1.1 Determine Location
Determine the best location for mounting the EC20 Antenna, with the following considerations.
• Coverage area —
The optimum coverage area spans
out at 65 degrees in a cone shape,
extending outward in front of the
antenna approximately 130 feet
(39.62 meters). The mounting
bracket provided with the antenna
will allow it to be pivoted and locked
into the best position for the
required coverage area.
• Cable routing —
The 100 foot (30.48 meter) coaxial cable must be able to be routed from the base station,
through walls and ceiling as needed, to reach the antenna. Note that the coaxial cable is
thick and relatively stiff, making it difficult to route around corners and through tight openings.
• Esthetics —
Some stores restrict the location of equipment mounted on the outside of stores, with
regard to distance from signage or visibility to customers, for esthetic reasons.
• Walk test —
To determine the best location for mounting it, you must do a walk test before
permanently mounting the EC20 Antenna. Remove power from the HME base station
and remove one of the base station antennas. Temporarily connect the enclosed antenna
adapter cable where you removed the base station antenna, and then connect the coaxial
cable to the adapter cable as shown in Figure 3. Route the coaxial cable to the area where
you would like to mount the EC20 Antenna, and connect the lightning arrestor and antenna
to the cable connector. Place the antenna temporarily in a position with its front surface
pointing to the area where its extended coverage is needed. Return power to the base
station. With two people using COMMUNICATOR®s (with fully charged batteries) and
pressing button B to communicate with each other, check transmission and reception
around the menu board and throughout the area where speed-team operators will walk.
If necessary, move the antenna and repeat the walk test until you find the location where
the best transmission and reception occur. You can now permanently mount the EC20
Antenna in accordance with the following instructions.

1.2 Mount Antenna
1.2.1 Assemble Antenna Bracket
The antenna bracket can be used without its
extension rod to mount the antenna about
2.5 inches (64 mm) from the wall or, with
the extension rod added, 5 inches (127 mm)
from the wall. Determine which will be best
for your installation and assemble the
bracket as needed. Refer to Figure 4.
NOTE: If the antenna will be mounted on the side of the building, where it may need to be
pivoted to nearly a 90 degree angle from the mounting surface, it will probably require using
the extension rod on the bracket.
1.2.2 Mount Antenna Bracket on Wall
• Hold the base of the antenna bracket against the wall at
the mounting location, and mark the wall through the
three screw holes in the base.
• Put the bracket aside and drill a 3/16 inch (4.76 mm)
hole in the wall at each of the marked spots.
• Insert one of the enclosed screw anchors all the way
into each of the drilled holes.
• Place the base of the bracket with its three screw holes
over the anchors and insert the enclosed screws
through the holes, screwing them all the way into the
anchors to hold the bracket securely in place.
• Drill a ¾ inch (19 mm) hole in the wall, centered
approximately 2 inches (50.8 mm) below the base of
the bracket, where the antenna cable will be inserted.
1.2.3 Attach Antenna to Bracket
• Screw the center hole on the back of the antenna onto the threaded tip of the bracket,
as shown in Figure 6.
• Pivot the antenna to the desired position, so the flat surface on the front of the antenna is
pointing toward the area where extended coverage is most needed, and lock it in place by
turning the lock knob clockwise to tighten it.
• Insert the antenna cable connector and cable through the hole in the wall below the
bracket, as shown in Figure 7.
• Be sure enough cable is left outside the hole for the antenna to be pivoted freely, and so
any rain water on the cable will drip off it rather than running down the cable toward the
hole, and fill the hole around the cable with weatherproofing sealant.

1.3 Run Cable
Inside the store, run the enclosed 100 foot (30.48 meter) coaxial cable from the base station of
the HME audio system, through walls and ceiling as needed, to where the antenna cable
comes through the wall.
1.4 Make Connections
• Remove the antenna from the top of the HME base station, and connect the EC20 antenna
adapter cable in its place. One end of the cable has a connector that fits the connector on
the base station, and the other end has a larger connector.
NOTE: For optimum antenna coverage, the EC20 adapter cable should be connected directly
to the base station connector, not to a splitter.
• Connect the other end of the antenna adapter cable to the coaxial cable.
• Go to where the EC20 antenna cable comes through the outside wall into the building.
Connect the enclosed lightning arrestor to the EC20 antenna cable, and then connect the
coaxial cable connector to the other side of the lightning arrestor.
• Attach a grounding wire to the ground connector screw on the lightning arrestor, and run
the other end of the wire to the nearest grounding point and connect it there.
• Using the mounting bracket enclosed with the lightning arrestor to mount the lightning
arrestor on the wall is recommended. This will act as a strain relief to prevent pulling on the
antenna cable. Use two screws (not provided) to mount the bracket on the wall before
attaching the lightning arrestor to it. Tighten the bolt on the lightning arrestor to secure it to
the bracket.
2. TROUBLESHOOTING
If any dropouts occur in the HME audio system’s transmission and reception, try loosening the
lock knob on the EC20 Antenna and repositioning it, and locking it in place again. Then do
another walk test for transmission and reception with the antenna in its new position. If
necessary, continue readjusting the antenna position and repeating the walk test until the
dropouts no longer occur.
