ATERIALS
There are three main components to the VR-803 V-TAC: the Full-Duplex Mobile
Radio Unit (MRU ); the V ehic ular Repeat er Base U nit (V RB); a nd the RF C ombiner.
The V-TA C i s desi g ned to mo unt o n t he f loo r or on a tray i n the tr unk o r unoccupi ed
section of a vehicle. The V-TAC is designed to be operated with an externallymounted a ntenna. The Installatio n Kit (M/A-COM Part #MA MROS0019) needed to
install t he V-T A C i s descri be d be low. The V-TAC is i ntended to be us ed with a CH 103 Control Head with Installation Kit, sold separatel y.
Table I lists the accessories that are included in the kit. Table II lists additional
options and accesso ries that m ay be purchas ed separate ly. (Note: T he Installation
Kit does not include an antenna. An antenna must be purchased separately, and the
V-TAC may not be installed unless an antenna is to be installed at the same time.)

Actions Notes
1. Plan the mounting locations of all
components (V-TAC, Antenna, and
Cables) and determine t he routes for
all wiring and cables.
♦ Determine the customer’s pr ef er ences, if
any, for location of components. Comply with
these preferences insofar as t hey are
consistent with safety, manufacturer
specificatio ns, and generally accept ed
professional practices.
♦ Make cert ain that drilling holes or insert i ng
scr e ws will not da mage or interfere w it h any
existing vehicle compo nents or w ir ing.
♦ Follow all manufacturer r equir eme nts a nd
guidelines for t he locatio n of components.

♦ As an assembled unit, the V-TAC weighs
over 20 lbs. It is unadvisable for t he V-TAC
to be hung from a surface; rather, the V-TAC
is best mounted onto a firm, f lat s urface.
♦ Mount the Base Bracket from the Base
Bracket Kit (Item 1) on top of the floor of the
trunk according to t he available space i n the
vehicle or on the surface of a tr unk tray.
♦ Screws f or mounting the bracket are not
included, as all installations are different, but
at least 6 screw s are required. Steel #10
screws are recomme nded.
♦ Screws for mounting the MRU into the Base
Bracket ar e included.
♦ The Bracket must be firmly held to the
surface in order t o pr event unreasonable
vibratio n from damaging t he V-TAC or

♦ Install two Extension Brackets from the
Extension Bracket Kit (Item 2), one on either
side, onto the Base Bracket using 2 screw s
from the kit. Tighten with a screwdriver until
the Extension Bracket is firm and flush to the
Base Bracket.
♦ The Exte nsio n Bracket can only be installed
onto the Base Bracket one way. See the
exploded view on the left for proper
alignment.
♦ Install the other two Extension Brackets, one
on eit her side, onto the Extension Brackets
just assembled.
