Now use a bit of Di-Electric Grease (found at any auto
parts store) and use it to create a water tight fitting for the
coax connection.
Use liberal amounts of Di-electric grease in the Coax
connector.
Attach the Coax to one of the two LNB ports (It does not
matter which one you choose). Wipe away any excess
grease with a towel. Push some Di-Electric grease up the
other connector so that it isn’t exposed.
Next step… use tie straps to keep all of your cables in place.
Secure the coax cable so that it is as secure as possible.
Final step… run a coax cable from the base of the
Magellan to the DirecTV satellite IN port of the DirecTV
receiver inside of the vehicle. Test to make sure you can
get a good TV signal.
