Installation Manual

Kingfisher Company, inc. STAR-ELT Manual
KCi #99420-MAN Rev 0.6 Page 12 of 29
IMPORTANT: The STAR-ELT can be connected directly to 100-120VAC nominal through
220-240VAC nominal AC line power with no setup changes.
11.3 Grounding
IMPORTANT: Proper grounding is required for safe and optimal operation
The STAR-ELT enclosure contains a ground clamp located on the left hand side of the cabinet
that must be connected to a dedicated earth ground, such as a ground rod located near the
transmitter. A common connection to antenna ground is recommended. Grounding cable should
be minimum 10 AWG and should be run with a minimum of bends in it.
11.4 Antenna
There are two ways to connect an antenna to the STAR-ELT. All antennas and feedlines must be
50Ω. The STAR-ELT is shipped with a coaxial jumper cable and a BNC-to-BNC panel-mount
connector in a separate bag of parts. If desired, the knockout on the top of the cabinet can be
removed and the panel-mount connector installed. The coaxial jumper cable should then be
connected between the BNC jack on the upper right corner of the STAR-ELT transmitter board
and the bottom of the BNC panel mount connector. A BNC antenna or feedline can be attached
to this connector.
The external BNC jack should not be installed if a 50 Ω coax feedline is used. The external
feedline should be brought in through conduit attached to the sides of the cabinet. If the external
feedline is larger than RG-58 coaxial cable, it should be connected with the appropriate adapter
(not included) to the coaxial jumper cable, which is then connected to upper left corner of the
STAR-ELT transmitter board.
11.5 Lightning Arrestor
The lightning arrestor (KCi #91016) adjusted to the proper operating frequency is included. The
BNC T-connector must be connected to the BNC jack on the STAR-ELT transmitter board. The
top T connection must be made to the BNC jumper cable that either goes to the BNC jack
mounted in the top of the cabinet or to the external coaxial cable. The lightning arrestor wire
should be connected to the bottom leg of the BNC T connection with its other end clamped into
the ground connection at the bottom of the enclosure along with the ground wire. If the operating
frequency of the transmitter is changed, a different lightning arrestor, cut to the new frequency,
must be obtained from KCi.
11.6 Battery (Optional)
When the optional AC power supply is used, a backup battery is required. This optional backup
battery sits in the bottom of the cabinet and connects to the optional STAR-ELT Power Supply
board with a 3-pin connector in the lower right corner (J1). A Kingfisher 12V sealed lead acid
battery or standard sealed lead acid 12V gel cell must be used with a minimum capacity of 5 A-
Hr. The battery should be rated for both discharging and charging over the full temperature
