Note: FM response is reduced to maintain distortion free
TV reception in the presence of strong FM signals. Preamp
will pass FM adequately in stronger signal areas, but is not
intended for critical weak signal FM preamplification.
INSTALLATION INSTRUCTIONS
PREAMPLIFIER CONNECTIONS
(Refer to Installation Diagrams I thru IV)
1a. Single antenna UHF or VHF only or UHF/VHF combined.
1.
Connect a 300 ohm twinlead from antenna to terminals marked ANT on preamplifier.
or 2. Connect a 75 ohm coaxial cable from antenna to terminal marked ANT on
preamplifier
or 1b. Separate UHF and VHF antennas.
Connect a 300 ohm twinlead from UHF antenna to preamplifier terminals marked
UHF ANT. Connect a 300 ohm twinlead from VHF antenna to preamplifier terminals
marked VHF ANT.
Be sure to leave enough slack in the twinlead to form a drip loop so rain
water does not enter the preamplifier case.
2a.
Using 300 ohm twinlead, connect downlead to terminals on preamplifier marked TO
POWER SUPPLY.
or 2b. Using 75 ohm coaxial cable, connect downlead to terminal on preamplifier marked TO
POWER SUPPLY.
Keep downlead as far away as possible from the input wire, a minimum of two inches.
Do not place any device in the downlead between the preamplifier and power supply.
A signal splitter, for example, may not pass power and would prevent the preamplifier
from operating.
3.
Mount preamplifier to the antenna mast as shown. If mast is attached to a chimney,
mount the preamplifier below the chimney top to avoid exposure to fumes.
BE SURE THE ANTENNA MAST IS WELL GROUNDED.
4.
Run the downlead as shown, using stand-offs. Form a drip loop where downlead
