INSTALLATION
Open the packing carton carefully, and save the
box and packing material for po ssible u se at a later
date . Inspect the FTV- 901R for any signs o f
damage in shipment . If there i s visible da mage,
contact the shipping company immediately, and
docu ment the damage thoroughly.
The FTV- 901 R has been designed for u se in many
areas o f the world, u sing variou s AC supply
voltage s. There fore, be fore connecting t he FTV-
901 R to the AC outlet, be ab solutely certain that
the po wer specification on the rear o f the trans­
verter matche s your local supply voltage . OUR
WARRANTY D O E S N OT C OV ER DAMA G E
CAU S ED BY A PPL ICATION OF IMPROPER
SU PPLY VOLTA G E . A s well, never connect the
po wer cord to a DC po wer source .
The tran sverter may be situated in any position
without loss o f per for mance. The only constraint s
regarding installation involve air circulation : the
tr an sverter should be located where there is free
passage o f air around the cabinet and heat sinks.
The tran sverter should be connected to a good
earth ground .
Plea se re fer to the dra wings for detail s o f correct
interconnection s bet ween the FTV- 9 01 R and the
FT- 901DM

ANTENNA CON SID ERA TIO NS
The antenna in stallation i s of critical i mportance in
V HF and U HF in stallation s. For satellite an d
moonbounce application s, height above ground i s
not a s critical a s i s t he case with local F M
in stallations. A minimu m distance o f 1 0 feet
should be maintained bet ween the V HF and HF
anter;mas . In all in stallations, the antenna should be
clear of surrounding object s, if the desire d p attern
is to be obtained .
Do not economize on coaxial cable, a s some
"bargain" cable s have very poor shield coverage,
and this may degrade per formance signific antly.
For the 430 MHz antenna, please u se a type N
connector, a s thi s type provide s a con stant
impedance on the antenna line. For short coaxial
runs we recommend type RG 8A

U coax . For very
long, run s, type R G- 17 A
