4-4 GROUNDING
Select a location for your transceiver which allows free access to the
front panel controls, good air circulation and rear clearance for
access to the rear panel connections.
Mobile installations:
An optional ЇС-МВ5 MOBILE MOUNTING BRACKET is available
for mobile installation of your 1C-475H. Select a location which.
can support the weight of the transceiver, and which does not inter-
fere with the normal operation of the vehicle.
Antennas play a very important role in radio communications. If
the antenna is inferior, your transceiver cannot deliver optimum
performance. А well-matched 5052 antenna and feedline will pro-
vide the desired effect. The transmission line should be a coaxial
cable. The antenna system should show a VSWR of less than 1:1.5
when using a 5052 coaxial transmission line.

1) Slide the nut, washer, and rubber gasket over the coaxial cable
and cut the end of the cable evenly.
2) Cut and remove 10mm of the outer vinyl jacket, and fold the
braid back over the clamp. The clamp end should be flush with
the end of the vinyl jacket. Evenly trim the braid ends.
3) Cut and remove 6mm of the shield conductor and the center
conductor insulation.
4) Soft-solder the center conductor. Install a center conductor pin
and solder it.
5) Carefully slide the plug body into place aligning the center
'conductor pin on the cable with the hold in the insulator inside
the plug body.
6) Complete the assembly by screwing the nut into the plug body.
