MODEL 6502 ACTIVE LOOP ANTENNA Mounting

REV E – PN 399058

MOUNTING

The Model 6502 is fitted with a mounting bracket threaded to

accept a tripod mount with standard 1/4 “ x 20 threads. To mount

the loop antenna, thread a ¼” x 20 mounting knob or fixture into

the base of the mounting bracket. Take care not to cross thread this

connection as permanent damage to the antenna mount could

occur.

OPERATION

SATURATION INDICATOR

This LED illuminates when input signal intensity exceeds the 1 dB

compression level of 5 volts per meter and stays on for about 1

second afterward.

POWER INDICATOR

This LED illuminates to show that the loop is “on” and functional.

When the charge on the battery has decreased to the point the

antenna calibration is no longer valid, the LED extinguishes. Note:

The antenna is still functioning and will provide reasonable output

signals until the batteries are exhausted.

USE OF CALIBRATION DATA

In order to calculate the field strength you must add the signal level

+ cable loss + antenna factor. The sum equals the relative field

strength. Cable loss should be measured periodically for each cable

used in testing.
