Need info on using a boom-mounted amplifier with a ST-2 antenna,I have no experience with these. I would like some feed-back on what to get,And how they work,And do you need a power source?

That's a short question that takes a LONG answer. ;-)

Yes you would need a power source for any preamp.
Here's an old thread that discusses how to power your preamp.

As long as you don't have any very strong signals in your area, it's worth experimenting with an antenna mounted amplifier.

As for what to get, well that can go from around $20 or so to well over hundreds of dollars.

Here's a link to a cheap experiment.

While the noise figure of that amplifier isn't the best, I've used to to show some friends locally what a preamp can do for them.

This is another view of a similar setup with approximate prices etc.
Mount the amplifier at the antenna and leave out the splitter if you don't need it.

And .... Here are some of my 'spare' amplifiers.



And another thread about getting power to your preamp.

First you've got to ask yourself: If there is a nearby lightning strike, and it blows the pre-amp up on the mast, can I get it down easily to replace it? My opinion from working with weak signal SSB/CW ham type stuff on 6,2, and 432 .... unless you're 100% hardcore in copying the weakest of the weak signals, then I would just put one in the shack. SO much easier to swap in/out or fix when broken, and it still helps copy the weaker signals. Don't get me wrong, I'm still PRO pre-amps, but just use it in the shack.
