Note - The screw holes are not symmetric so that the PVC base cannot be
improperly installed on the antenna. As such, you will have to place the base on
the bottom face of the mounting surface when marking the screw holes, before
drilling. Do not place the base upside down on the top face of the mounting
surface, as the resulting screw holes will not line up correctly.

Routing and Securing the Antenna Cable

The CDA-2B requires a 50

Ω impedance antenna extension cable such as RG-58U

(up to a maximum of 10 m (33 ft) in length) for proper operation. For more
information on cable length or low-loss cable, please contact your MID-TECH dealer
or MID-TECH Customer Service.

When choosing a route for the antenna extension cable:

Avoid running cables in areas of excessive heat.

Keep antenna cables away from corrosive chemicals.

Do not run the extension cable through door or window jams.

Keep the antenna cable away from rotating machinery.

Do not bend excessively or crimp the antenna extension cable.

Avoid placing tension on the cable.

Remove unwanted slack from the antenna extension cable at the receiver end.

Secure along the cable route using plastic tie wraps.

Caution - The RX 400p receiver provides 5 VDC across the antenna port.
Connection to incompatible devices may result in damage to equipment.

Warning - Improperly installed cables near machinery can be dangerous
