3.  Ensuring that there is no DC power applied to the 

DC Power Injector, plug the round connector of the 
outdoor Ethernet cable into the rear jack of the unit 
(Fig. 5), making sure the notch is correctly aligned 
with the tab on the jack as shown in Figure 6, then 
turn the round locking nut clockwise as you push in 
until it securely fastens onto the jack. 

 

WARNING:

 

Please verify that the round connector 

is properly plugged into the rear jack of the antenna 
prior to connecting DC power because it is possible 
to push it in the wrong way if enough force is used.

 

If DC Power is applied while you are attempting to 
insert the round connector into the jack, it is 
possible that, as you rotate the plug in an effort to 
find the key, DC power pins will momentarily touch 
the Ethernet pins. 

If this happens the Ethernet 

circuitry on the board will be damaged

. Any 

harm caused by this action will 

not

 be covered by 

the factory warranty and will be a billable repair.

4.  Attach the other end of the outdoor Ethernet cable 

to the Cat 5 DC Power Injector at port RJ-45 
labeled “To ANT.” 

 

NOTE:

  The Cat 5 DC Power Injector is not in a 

waterproof enclosure and must be protected 
from the weather.  It can be permanently 
mounted to a surface using the double stick 
tape found on the back of it. 

 
5.  Connect the Ethernet cable labeled “To PC or 

Router” from the Cat 5 DC Power Injector to your 
router, switch or hub. If you connect to a computer 
or PC, a crossover cable or adapter will be needed. 

 
6.  If your unit is placed on a non-metal pole or 

structure, install a #6 AWG insulated ground cable 
(not provided) to the ground connector in the back 
of the radio as shown in Figure 7. Use a self-
threading screw and a flat washer to fasten the 
earth lug. This provides safeguard against lightning. 
For maximum protection, YDI also recommends the 
use of its optional surge protected DC Injector 
available from your YDI dealer (part No. 304-
800620-002). This DC Injector has an additional 
wire to be connected to ground as shown on Fig. 8.
