Discadoo
Installation Instructions
The Discadoo has a rigid dome and at base with a mounting pad to accommodate slight variations in mounting surfaces. Thus, for proper
installation and best performance the antenna should be mounted on the highest at surface of the vehicle.
Caution: For proper performance the mounting area must be free of metal obstructions within 4” above or beside the antenna. An adequate metal
ground plane must also be provided by the vehicle (approx. 8” circumference) under the Discadoo.
Mounting Instructions:
To determine if a location is at, lay a ruler or other straight edge across the surface. There should
be little or no gap between the straight edge and the surface over a span of 4 inches. The mounting
surface must be cleaned thoroughly prior to application.
Pigtail Mount Bottom Exit: We have provided a pigtail length of very low loss, small
diameter coax. This allows the coax to make a sharp turn for mounting under headliners without
putting pressure on the antenna’s adhesive mounting. It also permits the installer to run the shortest
required length of low-loss coax from the pigtail to the transmitter. Maintaining short runs of low-loss
cable are very important at high frequencies. When you have decided on a mounting location, mark
the center of the location and drill a 5/8” diameter hole. Clean the surface around the hole with a
detergent cleaner and follow with a solvent wipe. Let surface dry thoroughly before continuing. Insert
the cable and the connector through the hole. Remove the backing material from the foam base of
the antenna and press the antenna rmly into place.

Pigtail Mount Side Exit: Looking at the bottom of the unit there is a black line on the protective paper on the foam backing. This line extends from
the center of the housing to the edge. With a razor knife, trim away on both sides of this line to create a slot that lines up with the hidden groove under it.
Now remove the caulking material that lls the hidden groove. The coax will lay in the groove when the antenna is installed on any at surface.
Hole Mount: When you have decided on a mounting location, mark the center of the locations and drill an 3/4” hole with the
X-ACT™ HS34 hole saw. Then, using a MB8 mounting kit, screw the

No Ground Plane Model: The no ground plane antenna’s tuning is strongly affected by any metal in the area of the antenna, above, adjacent to or
below it. The same applies to how the coax is draped as it leaves the antenna. Use a wattmeter or other SWR analyzer, take care to position the antenna free
from obstructions, and adjust the coax to drape for the best possible installation.
Note: The Discadoo™ can be painted with nonmetallic paint to match any car or to mount in a building, on a wall or on a ceiling.
