DANGER!!!

WATCH FOR WIRES! Installation of this product near power lines is dangerous. For your own safety, follow these important safety rules.

1. Perform as many functions as possible on the ground.

2. Watch out for overhead power lines. Check the distance to the power lines before starting installation. We recommend you stay a minimum of 6 meters (20 feet) from all power lines.

3. Do not use metal ladders.

4. Do not install antenna or mast assembly on a windy day.

5. If you start to drop antenna or mast assembly, get away from it and let it fall.

6. If any part of the antenna or mast assembly comes in contact with a power line, call your local power company.

DO NOT TRY TO REMOVE IT YOURSELF! They will remove it safely.

7. Make sure that the mast assembly is properly grounded.

WARNING!!!

Assembling dish antennas on windy days can be dangerous. Because of the antenna surface, even slight winds create strong forces. For example, a 1.0m antenna facing a wind of 32 km/h (20 mph) can undergo forces of 269 N

(60 lbs). Be prepared to safely handle these forces at unexpected moments. Do not attempt to assemble, move or mount a dish on windy days or serious, even fatal accidents may occur. ANDREW is not responsible or liable for damage or injury resulting from antenna installations.

INTRODUCTION

This manual covers the installation of the ANDREW 1.0m &

1.2m SMC antenna system with AZ/EL cap mount and Kusingle polarity feed.

For best results in the assembly process, perform each step in the same sequence as listed in this manual.

ASSEMBLY TOOLS REQUIRED

The following list of tools are those required for hand assembly and installation of the antenna.

1 - Ratchet Wrench ( ³⁄₈” Drive)

1 - 13mm Open/Box End Wrench

1 - 10mm Nut Driver

1 - Phillips Screwdriver

1 - 13mm Socket (

1 - Compass

³⁄₈” Drive)

SITE SELECTION

The first and most important consideration when choosing a prospective antenna site is whether or not the area can provide an acceptable “look angle” at the satellites. A site with a clear, unobstructed view from a suitable roof or wall facing south, southeast or southwest is required. Your antenna site must be selected in advance so that you will be able to receive the strongest signal available. To avoid obstructions, it is important to conduct an on-site survey with a portable antenna.

As with any type of construction, a local permit may be required before installing an antenna. It is the owner’s responsibility to obtain any and all permits.

ASSEMBLY AND INSTALLATION

The AZ/EL Cap Mount can be installed on a 2 ³⁄₈” or 3”

O.D. ground tube, roof, or wall mount depending on model. The appropriate mount should be assembled and in place before installing the AZ/EL cap.

As the AZ/EL cap mount is factory preassembled, there is no assembly required for the mount.

ASSEMBLING ANTENNA TO CAP MOUNT

Install four M8 x 60mm (2

³⁄₈”) carriage bolts (1) into holes in center of reflector and assemble to cap mount flanges.

(Reference Fig. 2.0) Install four lock washers (2) and hex nuts (3) on bolts. Tighten and torque to 11 ft.-lbs (15 N-m).

IMPORTANT! Bottom feed leg hole to be located as shown in Fig. 2.0.

INSTALLING CAP MOUNT ON MOUNT TUBE

Lift reflector/cap mount assembly and slide cap mount onto mount tube (Reference Fig. 2.1). Swivel antenna assembly until reflector faces southward.

Tighten M8 clamp nuts so that the antenna assembly is held stationary on tube, but can be swiveled with slight pressure.

FEED AND FEED LEGS INSTALLATION

Assemble feed assembly and feed legs to antenna as shown in Fig. 2.2.

Insert bottom feed leg (4) into hole in bottom edge of antenna (5). NOTE: Bottom feed leg is the one with a slight bend on one end of leg, lance on opposite end, and is shorter than the two side legs (6).

Install side legs (6) to antenna. From back side of antenna, secure with M6 x 30mm ( ¹⁄₄” x 1³⁄₁₆”) hex bolts and

¹⁄₄” special (⁷⁄₈” O.D.) flat washer (7 & 8). Do not tighten.

Insert bottom leg (4) into hole on center of junction block* (9) until lance on leg is engaged.

Insert one side leg (6) into junction block* (9) and secure with M6 x 30mm (

¹⁄₄” x 1³⁄₁₆”) hex bolts and ¹⁄₄” flat washer (7 & 10). Do not tighten.

Insert opposite side leg (6) into junction block* (9) and secure with M6 x 30mm hex bolt and

¹⁄₄” flat washer

(7 & 10). Tighten and torque bolts securing side legs to junction block and antenna to 4 ft-lbs (5.4 N-m).

Tighten self tapping screw (31) with bottom feed leg

(make sure screw engages hole in leg).

Refer to feed instructions packed with feed to assemble and install the feed assembly.

*NOTE: Junction block (9) is packed with feed assembly.

IMPORTANT: Sealing RF coaxial connector:

The copper-plated center conductor in the RF coaxial cable, which connects receiver to LNB, can experience electrolysis corrosion at the LNB connector. Moisture and DC current cause this type of corrosion. To prevent corrosion, apply a moderate coat of silicon grease to the center conductor and then wrap the entire connection with COAX-SEAL ® tape to seal.

ANTENNA ALIGNMENT PROCEDURE

Alignment with the satellite is obtained by setting polarization, elevation and azimuth. Charts 1, 2 & 3 are to determine the values for your earth station antenna site.

“ ∆L” is the difference between the earth station antenna site longitude and the satellite longitude. Use “ ∆L” and your earth station latitude to obtain polarization, elevation or azimuth setting.

POLARIZATION OF FEED

Loosen feed horn M6 clamp bolts (12) and turn feed clockwise or counterclockwise, depending on being east or west of the satellite as shown on Chart 1. Align marks on the horn clamp and appropriate mark on the horn scale clamp is installed with arrow pointed toward antenna as shown in Fig. 3.0. Keep cable groove on header in the down position when adjusting polarization. NOTE:

Single Polarity Feed is factory assembled for vertical polarity. If horizontal polarity is desired, rotate feed

90˚ (clockwise or counterclockwise).

ELEVATION

To obtain elevation value for your satellite, refer to chart

2. Loosen bolts in curved slots of AZ/EL Housing ¹⁄₈ to

¹⁄₄ a turn (Ref. Fig. 3.1). Turn elevation adjustment bolt clockwise to decrease elevation and counterclockwise to increase elevation. Align the edge of clamp with appropriate mark at the desired elevation reading

(Ref. Fig. 3.1). NOTE: Degree values shown on eleva- tion scale are Beam; that is when the antenna face is vertical mechanical elevation is 0˚, while the Beam

Elevation (signal) is 22.6˚. This will be an approximate setting. Optimum setting achieved when fine tuning.

Temporarily tighten elevation bracket nuts.

AZIMUTH

Use Chart 3 and determine your azimuth setting. Values in chart must be adjusted for magnetic deviation for your location for correct compass reading. Rotate the antenna and mount, pointing it to the correct compass reading for your location and satellite (Ref. Fig. 3.2). Slowly sweep the antenna in azimuth until a signal is found. If the desired signal is not found, increase or decrease elevation setting and repeat the azimuth sweep.

FINE TUNING

Use a signal strength measuring device for final adjustments to obtain maximum antenna performance.

Alternate between elevation and azimuth fine tuning to reach maximum signal strength until no improvement can be detected. Tighten all hardware. Torque for M8 round head, square neck bolts is 15 N-m (11 ft-lbs).
