Connecting the Antenna (3-bay to 8-bay)
32
(2) Using 1/2" stainless hardware ( 35 , 36 , and 39 ), attach the clamp half
( 40 ) loosely to the threaded rods.
(3) Using 1/2" stainless hardware ( 41 , 35 , 36 , and 39 ) and the spacer ( 42 ),
attach the saddle assembly ( 43 ) to the mount base.
(4) Repeat for the other mount assembly.
b. Using the hose clamps ( 44 ), attach the mounts to the three-way ( 45 ), four-
way ( 48 ), five-way ( 49 ), six-way ( 50 ), or eight-way ( 51 ) power divider.
Locate the mounts as close to the ends of the power divider as you can.
c. Mount the power divider to the mounting pole, with its outlet ports roughly
halfway along the antenna array. Secure it using the clamp halves ( 40 ) to
encircle the mounting pole as shown.
Install the optional
fine-matching
transformer (if
applicable)
One of the unique features of Shively Labs antenna systems is the adjustable
impedance-matching transformer (see Figure 20 ) optionally available with the
antenna. It allows the installer to compensate for changes in the input imped-
ance caused by the installation (tower, conduit, ladder, etc.).
NOTE
The transformer may be oriented in whichever direction you wish. Make
it easy for yourself to reach for adjustment at startup.
Install the transformer at your antenna array input. This will be at the input
flange of the power divider ( 29 , 45 , 48 , 49 , 50 , or 51 ). Transformer mounts
are generally similar to feedline mounts and should be installed in the same
manner.
Connect the antenna
cables.
CAUTION
All O-rings are made of silicone. Do not lubricate them with silicone
grease, as this will soften the O-ring. Use only a light lubricating coat of
O-Lube (provided) or petroleum jelly; too much may hamper electrical
contact and contaminate the interior of the system.
Be sure the O-ring is properly seated in its groove and not pinched
between the flange contact surfaces.
a. Coat each O-ring ( Figure 20 on page 36, 26 ) lightly with O-Lube (supplied
with the antenna), then install it in the O-ring groove in the flange.
b. Before connecting each flange, make sure an inner conductor connector is
in place in the inner conductor of the flange.
CAUTION
Do not overtighten the flange nuts. Overtightening may damage them.
c. Using the 7/8" EIA flange hardware kits ( 27 ), connect the unlabeled input
ends of the antenna bay cables ( 31 ) to the power divider outputs. Tighten
flange nuts in accordance with Table 1 on page 1.
