5.8 GHz 200-900mw + Fatshark goggles: Is this a good first FPV setup?

I would like a setup that goes 1 mi or over. I like the fatshark head set and would like a transmitter/receiver to connect to it. is this even possible because the goggles have a built-in transmitter?
Also What is better on 5.8?- 100,200,400,500,600,800, or 900mw?

One of these:

Fav so far http://hobbywireless.com/index.php?m...products_id=22

or even:

To go with this:

Could you tell me if either of these setups are good and can work together?

Look for the Foxtech/BevRC/Hobbyking 5.8Ghz 200mw. Make sure you get the one with the RC305 receiver. DOES NOT work with FatShark.

Look for the ImmersionRC 5.8ghz 600mw. ImmersionRC works with Fatshark.

More mw does not mean more range. Invest in antenna instead. Look for the Cloverleaf. You can build them or buy them. Avoid chinese mass-product cloverleaf.

Well I was typing too fast. If you absolutely want to fly far far far. Look for a Helical antenna. Anyways, there's plenty of thread on antennas, you'll find you way.

I really appreciate the post. So your saying the ImmersionRC 5.8ghz 600mw will go 1 mile, and is better than a 1.2/3 setup?

5.8 is good for countries where you can't use 1.3. Otherwise you should probably use the 1.3 either from foxtech or bevrc. Bevrc is my fave and they have some awesome deals

I have the 800mw 1.3ghz from them. It heats up a bit but its normal. Don't get the 1500mw unless you have some serious ventilation plan to go 50mph all the time.

As a noob myself, I think you'll find FPV requires a lot of reading and preparation before you're ready to make informed decisions for purchases.

There are so many variables (quality and compatibility of components, type and configuration of antennas, interference from the environment and your own aircraft, your own competence with the assembly and use of the equipment, local laws regarding radio use) that nobody can give you useful information about any given system's range without knowing a LOT more information about your proposed setup.

To assist with your most recent questions:
Most FPV receivers and transmitters will have a range of different frequencies (channels) they can operate on - generally, they're listed in the specifications and there's usually 8 channels the operator can choose from. You need both your transmitter and receiver to have a matching frequency, so they can talk to each other on that channel.
(As a rule of thumb, FatShark & Immersion use frequencies ending with 0, the HobbyKing/BevRc/Foxtech gear uses frequencies ending with 5 - this might make things easier when glancing through spec sheets)

The power of your transmitter is NOT the most significant factor in getting good range from your equipment. The selection of appropriate antennas and setting up your aircraft and ground station well will be much more important. Don't over-simplify by assuming that big numbers on your transmitter and antenna will ensure the greatest range - this is definitely not the case.

Better for what? It's just not that simple. If you had any idea how antennas work, you'd know what a pointless question that is. Different types of antennas have different transmission patterns, and are more suited to particular applications. That's why there's so many different types.

That antenna is about the same as the stock one, worse than inverted vee and cloverleaf. If I were you, I'd buy inverted vee for 1.3 ghz for $15-$20 from either foxtech or somewhere else. The 1.3ghz lowpass is perfect fit for your tx.

To be slightly more helpful to your original question: An ideal setup for a noob goes something like this.

5.8ghz 200mw transmitter and 5.8ghz receiver from Foxtech or similar
480-600 TVL camera from any number of vendors, SecurityCamera2000 have been very popular lately
Fatshark goggles, if that's what you want.
5.8ghz cloverleaf and skew planar wheel antennas
You will also need an aircraft, and a battery for the receiver.

The above setup should be good for about 1-2km, provided you set it up correctly.

There are a few possible variations to this, depending on how much money you want to spend. You could use a small moniter, rather than goggles - this could save $200 or so. You could also get an all-in-one package, where the receiver is built into goggles - this simplifies your setup considerably.

You also need to decide which frequency you're going to use. In some countries, 900mhz and 1300mhz are illegal and/or prone to interference from commercial use. If you're using a 2.4ghz radio for RC (and most hobbyists are these days) then you can't use 2.4ghz for your video link.
