You will need SWG Guides. TaultUnleashed has the Star Wars Galaxies Guides you want. Check out a SWG Guide used in the past by hundreds of thousands of members. Here is the Star Wars Galaxies Guide:
Is Restuss dominated by the opposite faction on your server? Are you happy with the fast antenna xp, but want to grind faster? Well, you're in luck!
First, your toon needs to be commando. Even if that's not what you want to be, it's worth the respec IMO because of how easy this makes the antenna quest. Next, get a crate of swoops, then head out to restuss and find yourself an antenna. ALL YOU NEED TO DO IS GET CLOSE!!! Even if there are 30+ rebs around, you should be able to swoop in and get within 20m of the antenna (I was doing that at lvl 10). You will likely die, but that does not matter. Alive or dead, bring up the radial menu on the antenna, and as a commando, you will see the "Set Charges" option. Choose it, and a countdown will begin. Once the countdown ends, radial the antenna again and choose "Set Charges" or "Arm Charges" (for some reason the option name randomly changes) - BOOM! The antenna will blow up.
This works well for two reasons - #1, you can do it while dead, incapped, whatever, as long as you're somewhat close to the antenna (20m is approx.), and #2, it's MUCH faster than actually shooting it down, can be done solo, and any lvl can do it.
Just make sure you're the only one doing this - after you start the process, if another commando tries it, his mission will fail.
And have fun with the opposite faction players who smugly think they're keeping you from grinding... only to see the antenna blow up next to your corpse.
