(61) ANT 1
ORION is equipped with three antenna
connectors; two for transceive, one for
receive only. ANT 1 is for connection of a
transceive antenna. Nominal impedance is
50 ohms. The optional automatic antenna
tuner (if installed) uses the ANT 1 connector.
Connect a suitable antenna to this jack, fed
with 50-ohm coaxial cable. This antenna is
selected for use by the operator by pressing
buttons on the front panel (see description of
buttons 2 through 7 earlier in the manual).
Also see the descriptions for (62) ANT 2 and
(71) AUX RX.
(62) ANT 2
Like ANT 1, ANT 2 is a transceive antenna
jack, with nominal impedance of 50 ohms.
The optional automatic antenna tuner (if
installed ) is not operable for an antenna
connected to ANT 2.
Connect a suitable antenna to this jack, fed
with 50 ohm coaxial cable. This antenna is
selected for use by the operator by pressing
buttons on the front panel (see description of
buttons 2 through 7 earlier in the manual).
Also see the descriptions for (61) ANT 1 and
(71) AUX RX.

(63) DC IN
This is the dc input connector. ORION
requires 23 amps at +13.8 Vdc nominal for
100 watts output power. The supply voltage
can range from +12.8 to +15.0 Vdc but
+13.8 Vdc is the optimum value.
We recommend using the included dc power
cable (P/N 86095). We have also included
spare connector pins (P/N 41020) and a
spare two-pin power connector shell (P/N
35165) for building your own cable. The
power supply plug will attach in only one
direction to the polarized two-pin dc
connector on ORION's rear panel. Use no
less than #14 gauge (#12 recommended)
stranded wires for three-foot long
connections to accommodate the high
current demand during transmit. Use
heavier gauge wire for longer power supply
leads.
(64) FUSE 25 A
ORION is equipped with a 25-ampere blade-
type automotive fuse. A replacement has
also been provided in the transceiver
packing kit.
(65) GND
The GND wingnut is for connection of
station ground or counterpoise. See A
WORD ABOUT GROUNDING in Chapter 1.
