horizontal until a reasonable tension is applied to the diagonal wire going to
the top of the mast. This applies to the smaller models as well.
o Failure to make the loops closely the same size and shape will result in less than
optimal results, especially below 4 MHz!
-
- Switching unit (combiner) installation
o Remove the cover of the switching unit so that the loop terminals are exposed.
See picture on next page.
o Route the northeast loop balanced line through one of the holes in the bottom of
the switching unit. Connect the red (+) wire to the NE+ terminal and the black (-)
wire to the NE- terminal.
o Route the southwest loop balanced line through one of the holes in the bottom of
the switching unit. Connect the red (+) wire to the SW+ terminal and the black (-)
wire to the SW- terminal.
o Route the southeast loop balanced line through one of the holes in the bottom of
the switching unit. Connect the red (+) wire to the SE+ terminal and the black (-)
wire to the SE- terminal.
o Route the northwest loop balanced line through the remaining hole in the bottom
of the switching unit. Connect the red (+) wire to the NW+ terminal and the black
(-) wire to the NW- terminal.
o Verify that the balanced lines are connected to the appropriate terminals. You
should see a repeating pattern of wire colors (i.e. red-black - red-black - red-black
- red-black).
o Note: The array will NOT be directive if the balanced lines are not connected in
the proper order!
o Reinstall the cover onto the switching unit.
o Mount the switching unit to the mast with a couple of tie wraps, the bottom guy
bracket makes a nice place for the top tie-wrap. See picture.
o Connect the ends of the RG-6 delay line to the two side by side at the same level
F- female connectors on the front of the switching unit (see picture below).
o Connect the RG-6 feed line to the controller to the F-female top connector on the
front of the switching unit. It is the connector on upper part of the box.
o Is recommended the use of coax tape on the RG-6 connectors to protect them
from the weather.
WARNING!
Do not insert any device in the RG-6 or the transmission line between
the Combiner and the Controller of the SAL antenna. Most devices are
a short circuit for DC and the command pulses and 15 V DC are sent to
the combiner using the transmission. This can damage the device, the
Combiner and Controller of the SAL antenna.
