Congrats!
I am going to suggest that you join a local ham club, if you haven't already,
Although it's great to ask questions here and other places online (such as eHam.net), it's better to get some experienced guys to help you out in person.
As an example, I passed my General exam in 2011, but at the time, I was living in NYC, in a building that did not allow any kind of antennas up on the roof. Because of that, I never bothered to get an HF rig.
However, on Feb. 1st of this year, I moved to a house in Cape Cod, MA and I have been to a meeting and joined the local club; already I have offers from two guys to help me choose a site and type of HF antenna.
I bought a Yaesu FT-450D, as I have limited space for a rig. It is feature laden and is under $1000. You can wait for a sale, like I did, and get it for under $800.00! Not bad for a 100 watt full featured rig.
As has been suggested, you need to know more about what you want to do, and what kind of space you have to use, and how much money you want to spend, in order to determine what type of antenna. In my case I am going to look into wire antennas, as they are the least costly, and can be made fairly easily by hand.
That is where having in-person help will be invaluable!
Once again, congrats!
