Coupling, joining and stacking TV antennas
Posted by Denny Duplessis

Coupling TV antennas

Two antennas aimed in different directions to receive channels located in multiple directions.

Stacking TV antennas

Two antennas aimed in the same direction to improve overall performance. 

Coupling and stacking antennas can be very successful but there are procedures you must follow to get the best results.

Below is an example of the HD Stacker antenna coupled with the EZ HD antenna. 

EZ HD and HD Stacker antennas coupled together

The top EZ HD antenna > is aimed in the direction of the stronger TV signals. The lower HD Stacker antenna >  is aimed in the direction of the weaker TV signals. We recommend the CC 7870 antenna coupler > to join the antennas together. In the picture the coupler is located on the mast between the two antennas. Also in the picture is the  preamplifier > located on the mast just below the top of the tripod.

The procedure for coupling or stacking antennas is the same.  The only difference is the aiming of the antennas.

1.  The antennas should be spaced at least 2 feet apart on the mast.
2.  The coax cable leading from each antenna to the coupler inputs should be the same length. 
3.  A preamplifier is highly recommend to get the best results.
4.  The cable leading from the coupler output to the preamplifier 
input should be no longer than a few feet in length. 

TV antennas that are aiming in different directions  will experience a slight reduction in performance. This reduction in performance can not be avoided. 

TV antennas stacked together aiming in the same direction will usually experience an increase in performance.

When stacking antennas aiming in the same direction to improve performance it is best if the two antennas are identical. 

The proper order for Stacking and coupling TV antennas is as follows.

  • Run coax cable of the same length from each antenna to the antenna coupler input connections.
  • Run coax cable from the antenna coupler output connection to the preamplifier input connection.
  • Connect the down lead cable that leads into your home to the output connection of the preamplifier. 
  • Inside your home on the other end of the down lead cable connect to the input connection of preamplifier power inserter included with the preamplifier.
  • From the power inserter output connection to the TV or signal splitter and then from the splitter to the TVs.
