All Loran-C receivers work on this

principle.

Most modern receivers

also

display

latitude/longitude.

The receiver

takes the TD information

and, using

a

complex

mathematical

formula,

converts it to Iatitude/

longitude position

data. You can

display

both TO's and

latitude/longi-

tude

on the UltraNav to determine

your

position.

If

you

wish to know more about

Loran-C,

order the United States

Coast Guard's book

"Loran-C USER HANDBOOK."

It's an excellent

book that describes

Loran in

greater

detail.

INSTALLATION

-

ELC-1

Loran-C MODULE

When

choosing

a

mounting

location,

remember to install the

ELC-1

where it's clear of other

antennas, wires,

masts,

or other obstructions.

A

high

location is

preferred,

however for

lightning protection,

the

antenna

shouldn't

be the

highest pad

of the boat.

The antenna should

be

mounted

vertically.

Make certain it is as far

away

as

possible

from

VHF

radio antennas.
