12. Attach the rectangular feed tube to the antenna socket. Make certain the large round hole for the spacer is positioned

as shown in Figure 7. Tighten bolt while holding nut.

13. Attach the LNB Adapter to the feed tube with #8 hex insert nut and 1" long Phillips head scre w.  See Figure 7. 

Do not over-

tighten to the point of deforming the feed tube and the LNB Adapter.

ing LNBs. See Figure 8.

B e f o re making any wire connections, read “Connections”, Page 18. 

The next steps involve making the coaxial cable

i n t e rconnections between the LNBs, multiswitch and the satellite receivers. First, choose one of the mounting location
options for the multiswitch listed below that best fits your installation. Use approved installation kits with high quality,
low loss RG6 coaxial cable to insure the best perf o rmance under all conditions. 

All coaxial cables must be gro u n d e d

outside at the point of entry. Contact a licensed inspector or electrician in your area for assistance. General gro u n d-
ing re q u i rements are outlined in Figures 11 and 12.

M U LTISWITCH LOCATION OPTIONS:

• Option #1: Mounting a weatherproof multiswitch to the back of the antenna as shown in Figure 9. This location

is  simplest  for  installations  that  use  one  receiver  since  only  one  cable  enters  the  building.  If  this  option
is  selected,  connect  the  LNBs  to  the  multiswitch  per  the  following  instructions  while  on  the  ground  with
coaxial cables. Depending on your model, a 4-cable set may be included for ease of installation.

• Option #2: Mounting the multiswitch inside the house. This option provides the best weather protection and may

p rovide the easiest access for future wiring changes, such as adding additional satellite receivers. 

• Option #3: Mounting the weatherproof  multiswitch under  the building  eaves at the  point of cable entry. This

option provides excellent weather protection to the wire connections and the switch. It eliminates the coaxial gro u n d
blocks since the multiswitch also serves as a grounding block for the four LNB cables connected to it.

NOTE FOR  OPTIONS #1 and #3:

Typically in a single family home,  the RG6 cable for the supplied 4 x 4 mulitswitch  does

not  exceed  100  feet  from  the  satellite  receiver(s)  to  the  LNBs.  For  installations  where  each  RG6  cable
run from the satellite receiver(s) to the LNBs exceeds 100 feet, such as often encountered in a commercial or multi-dwelling
building, it is recommended that you use an AC-powered multiswitch (not supplied). An AC-powered multiswitch
powers  the  multiswitch  and  the  LNBs  directly  from  an  AC/DC  power  module  so  that  the
satellite  receiver  is  capable  of  driving  a  longer  RG6  cable.  Contact  Channel  Master  Technical  Service  for  an
Application Note concerning such installations. Other manufacturers may offer similar pro d u c t s .

16.  Even though all the above mutiswitch location options are used by installers, this manual will concentrate on option
#1. If an installer chooses to install the multiswitch in the house or at the point of entry to the house, then cables of pro p e r
lengths must be cut. To prevent corrosion, weatherproof outdoor connectors with rubber o-rings must be used for
all outdoor connections. See Figures 11 and 12 for general wiring diagrams.
