Kingray MHV34 User manual

INSTALLATION MANUAL
• A masthead amplifier is designed
to amplify low signal levels for both
analogue and digital applications.
• The amplifier gain should be selected
to suit each individual environment.
• Mount with polypropylene securing
strap on to mast or mount to a wall
with cable connectors at the bottom.
• Best mounting location for masthead
unit is on mast 30 cm to 100 cm
below antenna.
• Ensure weatherproof strips remain
in place.

MODEL MHV34
Masthead Amplifier
Thank you for selecting an Australian designed and built
masthead amplifier.
1. Check there is no earth braid touching the centre
conductor on the coaxial cable.
2. Is there more than one outlet? Check the
splitter box, the power supply must be connected to
the coaxial outlet that feeds the AC/DC leg of the
splitter box to pass power to the head unit. (Check
if LED is on).
3. Is there now too much signal causing an
overload effect to the VCR? Try turning down
the gain controls on the masthead unit, or select a
smaller dB rating amplifier.
4. If there is a white line moving through the
picture:
Try a PSK06 14 V DC power supply.

The MHV34 is a low noise masthead amplifier designed to amplify VHF channels 0-12 by 38 dB and
diplex UHF channels 28-69.
Note: Place MHV34 amplifier near the antenna(s) to improve the S/N ratio.
OPTION (A)
Amplifying VHF CH 0-12 by 38 dB
1) Connect VHF antenna to VHF input.
2) Connect Power Supply coax lead to output terminal.
OPTION (B)
Amplifying VHF CH 0–12 by 38 dB Diplexing UHF
CH 28-69 with no gain.
1) Connect VHF antenna to VHF input.
2) Connect UHF antenna to UHF input.
3) Connect Power Supply coax lead to output terminals.

Use models:
PSK08/F - 17.5 V AC, 100 mA.
PSK06/F - 14 V DC, 150 mA.
All these models are short circuit protected, allowing a short circuit to be tolerated for an indefinite
period without harming to the unit. Removal of the short circuit will immediately allow the power supply
to operate normally.
For your safety, install any external aerial to AS1417.1.
