SLIDE 2

UHF Link Radio VHF (2 meter) Repeater Power Supply Isolator Duplexer

SLIDE 3

Transmitter = 146.980 MHZ
Power output = 45 Watts (27W out duplexer)
Modulation = 4.5 K HZ
Receiver = 146.380 MHZ
Sensitivity = .28uV (.6uV through duplexer)
Squelch set to .5uV
PL tone = 100.0 HZ
No measurable desence through duplexer.
Antenna sweep (new antenna)
19db Return loss at transmitter frequency
24db Return loss at center frequency of antenna

GE Master Pro SN: 7530892

Repeater Performance

SLIDE 4

RECOMMENDATIONS

PRIMARY CONCERNS

1 – LIGHTNING PROTECTION 2 – INTERMOD 3 – EQUIPMENT STABILITY

SLIDE 5

R 56 STANDARD

EVERYONE MUST COMPLY

SLIDE 6

LIGHTNING ARRESTOR

Mount repeater on shelf Mount Radio under shelf Mount isolator on shelf

INSTALL RACK SHELF

Should be on Ground Buss At entry port DUPLEXER Should be mounted to rack WIRES AND CABLES Should be in protective loom and secured to rack

SLIDE 7

Ground wire needs to be replaced

SLIDE 8

Coax should be in cable tray Cable Tray

SLIDE 9

Power Cord should not be on the floor Power Surge Protector Unused wires need to be removed Ground wire needs to be replaced with proper type and location

SLIDE 10

Lightning arrestor should be here

EQUIPMENT GROUNDING

SLIDE 11

Lightning arrestor should be mounted here

ENTRY PORT

GROUND PLATE Need ground wire from lightening plate to outside ground

SLIDE 12

Antenna properly mounted on good support

Wire ties or electrical tape should never bee used on a tower Coax should not be strapped to the tower leg

SLIDE 13

Coax should not be laying on the ground

SLIDE 14

Coax should be properly installed.

SLIDE 15

Ground Kit should be on Heliax

Heliax should be in cable ladder with others Proper cable clamps should be used

SLIDE 16

SLIDE 17

SLIDE 18
