with either a three prong plug for 120 Vac use. It is to be  
inserted into only the type of receptacle for which they specifi-  
cally designed . Do not cut off the round grounding pin in order  
to be able to fit into a two prong receptacle as this could cause  
injury and will void the warranty.

13. Lightning - For added protection for this product during a  
lightning storm, or when it is left unattended and unused for  
long periods of time, unplug it from the wall outlet.  
19. Replacement Parts - When replacement parts are required,  
be sure the service technician has used replacement parts speci-  
fied by the manufacturer or have the same characteristics as the  
original parts. Unauthorized substitutes may result in fire,  
electric shock or other hazards.  
14. Power Lines - An outside antenna system should not be  
located in the vicinity of overhead power lines, other electric  
light or power circuits, where it can fall into such power lines or  
circuits. When installing an outside antenna system, extreme  
care should be taken to keep from touching such power lines or  
circuits as contact with them may be fatal.  
20. Safety Check - Upon completion of any service or repairs  
to this product, ask the service technician to perform safety  
checks to determine that the product is in proper operating  
conditions.  
15. Overloading - Do not overload wall outlets and extension  
cords as this can result in risk of fire or electric shock.  
21. Outdoor Antenna Grounding- Before attempting to install  
this product, be sure the antenna or cable system is grounded so  
as to provide some protection against voltage surges and built-up  
static charges.  
a. Use No.10 AWG (5.3mm ) copper, No.8 AWG (8.4mm  
(aluminum, No.7 AWG (10mm ) copper-clad steel or bronze  
wire or larger, as ground wire.  
b. Secure antenna lead-in and ground wires to house with stand-  
off insulators spaced from 4 feet (1.22m) to 6 feet (1.83m) apart.  
c. Mount antenna discharge unit as close as possible to where  
lead-in enters house.  
16. Object and Liquid Entry - Never push objects of any kind  
into this product through openings as they may touch dangerous  
voltage points or short-out parts that could result in a fire or  
electric shock. Never spill liquid of any kind on the product.  
17. Servicing - Do not attempt to service this product yourself  
as opening or removing covers may expose you to dangerous  
voltage or other hazards. Refer all servicing to qualified service  
personnel.  
18. Damage Requiring Service - Unplug this product from the  
wall outlet and refer servicing to qualified service personnel  
under the following conditions:  
a. When the power-supply cord or plug is damaged.  
b. If liquid has been spilled, or objects have fallen into the  
product.  
d. A driven rod may be used as the grounding electrode where  
other types of electrode systems do not exist. Refer to the  
National Electrical Code, ANSI/NFPA 70-1984 for information.  
e. Use jumper wire not smaller than No.6 AWG (13.3mm )  
copper or equivalent, when a separate antenna grounding elec-  
trode is used.  
c. If the product has been exposed to rain or water.  
d. If the product does not operate normally by following the  
operating instruction. Adjust only those controls that are  
covered by the operating instructions. An improper adjustment  
may result in damage and will often require extensive work by  
a qualified technician to restore the product to its normal  
operation.  
e. If the product has been dropped or the cabinet has been  
damaged.  
f. When the product exhibits a distinct change in performance  
- this indicates a need for service.

PIDA-550  
PIDA-750  
PIDA-1000  
The PIDA series of broadband distribution amplifiers  
are high quality push-pull amplifiers producing signal  
with extremely low distortion and high output. These  
amplifiers are designed for RF distribution systems for  
hospitals, schools, apartment complexes, hotels and  
similar applications. It can also be used as a headend  
launch amplifier in conjunction with the PHC-12U  
headend combiner. The enclosure is made of  
aluminum to assure reliable heat sinking and corrosion  
resistance.

Distribution  
Theoutputlevelsofthemodulatorshouldbethesameastheoutputoftheoff-airstripamplifiers. TheM860  
modulators are usually combined with either the SP860 signal processor, LBS/MBS/FMS/UBS series strip  
amplifiers. Two methods are suggested to combine strip amplifier, modulator and processor outputs which  
are then amplified with the PIDA distribution amplifier serving as a launchamp.  
The PHC-12U twelve channel passive headend combiner consists of two rows of directional couplers  
combined by a hybrid splitter. The directional coupler combining provides high isolation (40 dB) between  
the inputs. Normally, the odd channels are combined on one row while even channels are combined on the  
other row of directional couplers. The combiner loss is 16 dB per channel.

Another method of combining signals uses three hybrid splitters per headend rack. The odd channels are  
combined in one splitter, the even channels in another splitter and the two splitters are combined to a single  
output with a third splitter. Each rack is then combined with a final splitter prior to the PIDA amplifier.
