BEFORE YOU BEGIN 
Read  this  manual  and  separate  Consumer  Product  Safety 
Commission  information.  For  your  safety  and  convenience, 
plan  each  step  of  the  installation  and  purchase  the  nec-
essary  hardware  in  advance.  The  order  in  which  you 
perform  the  steps  and  the  hardware  required  depends  on 
the mounting and connection methods you choose. 
 
Note: There  is  no  built-in  VHF  feed  thru  feature  on  these 
antennas. 
 
We recommend two people assemble the entire antenna on 
the  ground, and  then mount  the  assembled  antenna  on  the 
mast.  
 
Warning: When  you  install  your  antenna,  use 
extreme  caution.  If  the  antenna  starts  to  fall,  let  it 
go!  It  could  contact  overhead  power  lines.  If  the 
antenna  touches  the power  lines or  guy  wires it 
can cause electrocution and death. Call the power 
company to remove the antenna.  
 
Do not attempt to remove it yourself. 
 
 
ASSEMBLING THE ANTENNA 
1. Press the supplied end plugs into the ends of the 
antenna booms. 
 
 
 
2. For  Model  U8000  only: Use  the  supplied 
hardware to loosely attach the supplied mast clamp 
assemblies  (mast  clamp,  backup  plate,  U-bolt  and 
locknuts)  through  the  holes  on  the  cross  booms.  
Note: There  is  an  extra  mast  clamp,  U-bolt  and 
lock nuts to secure the aluminum leg at the bottom 
plastic  connector  marked CONNECT  LEAD-IN 
HERE. 
 
 
Model U8000 
 
 
 
 
For Models U2000 and U4000: The mast clamps are pre-
attached  to  the  main  boom  and  you  need  only  attach  the 
U-bolts and nuts 
 
WARNING: Installation of this 
product near power lines is 
DANGEROUS.  For your safety, 
follow the installation directions. 
       
						

							 
CONNECTING LEAD-IN CABLE TO THE ANTENNA 
 
We  recommend  RG-6  cable,  and  if  you  prepare  your  own 
cable, a quality F-connector.  
 
Note: If  you  prepare  your  own  cable,  slide  the  300  to  75 
Ohm  matching  transformer’s  weather  boot  onto  the  cable 
before you attach. 
 
1. Slide the transformer’s spade terminal ends around the 
antenna’s  lead-in  terminals  marked CONNECT  LEAD-
IN  HERE tag.    Secure  them  with  the  supplied  flat 
washers and large wing nuts. 
 
Note: Models  U2000  and  U4000  do  not  have  a 
CONNECT  LEAD-IN  HERE tag.    Connect  the 
transformer’s  spade  terminal  ends  to  the  terminals  on 
the middle plastic insulator. 
  
2. Screw  the  F-connector  onto  the  300  to  75  Ohm 
matching  transformer.    Then  slip  the  weatherboot  over 
the  connection.   Note: If  you  use  a  cable  without  a 
weatherboot,  cover  the  connection  with  weatherproof 
tape. 
ATTACHING THE MAST 
We  recommend  that  you  get  the  help  of  another  person 
before  you  put  up  the  mast  or  attach  your  antenna  to  it.  
How  you  set  up  the  mast  depends  on your  specific 
installation.    Refer  to  the  separate  Consumer  Product 
Safety Commission information for recommended methods. 
 
1. Slide  the  antenna’s  loosely  attached  mast  clamp 
assemblies  over  the  top  of  the  mast  and  tighten  the 
nuts  just  enough  to  hold  the  antenna  in  place.    Take 
care not to overtighten the nuts. 
 
Caution: The  crossover  wires  must  not  touch  the 
antenna  boom,  the  mast  or  each  other.    If  necessary, 
carefully bend the crossover wires to provide at least ½ 
inch of clearance. 
  
2. For Model U8000 only: Secure the CONNECT LEAD-
IN  HERE plastic insulator to  the  mast  by  inserting  its 
aluminum  leg  between  the  U-bolt  and  the  mast.  
Loosely  tighten  the  locknuts to  hold  the  leg  against  the 
mast but do not overtighten. 
 
Note: This U-bolt will face the opposite direction as the 
other two U-bolts on the antenna mast  
 
 
 
3. Rotate  the  antenna  so  its  front  (the  side  with  the  wire 
bowties)  faces  toward  the  TV  stations  you  want  to 
receive.  Finally,  tighten  all  mast  clamp  assemblies,  but 
do not overtighten. 
ROUTING THE CABLE TO YOUR TV 
 Use plastic tape to secure the coaxial cable to the mast 
at about 3-foot intervals. 
 Use coaxial nail clips every few feet to secure the cable 
between  the  mast  and  where  the  cable  enters  the 
house. 
 Use  a  75-Ohm grounding  block  at  the  point  where  the 
coaxial  cable  enters  the  house.    Read  the  Consumer 
Product  Safety  Commission  information  for  grounding 
instructions. 
 Use  a  drip-loop  before  the  coaxial  cable  is  routed  into 
the house. 
 Use  a wall-through  tube  to neatly  route  the  coaxial 
cable through the wall.
