Just thought I would put this question out there to see what kind of response I would get.

     What is the best SW antenna?

I have a Icom R75 receiver.

No antenna, whether horizontally or vertically polorized is immune from man made noise if it is in a noisy location. Grin

200 feet of wire over the tops of all the trees in an apple orchard worked for me. Then again I lived in The Bush.

I think KC9EJG was just looking for opinions. True, there are many...... Wink

Seems there aren't too many opinions out there after all?

Don't let it bother you Richard. It was a fair question.

Best of luck.

I was the only one who was rude.

The others didn't answer because your far-too-brief question is unanswerable. Eham has some very technically savvy hams, often with advanced degrees and long experience in various branches of engineering. Many here have decades in the hobby. Some have decades in military and government communication. But you have to provide a well-crafted question. Otherwise you're wasting their valuable time

Best SW antenna? For DX or stateside or some combination?
Best SW Antenna? SW meaning 2 MHz, 15 MHz? 30 MHz or some combination?
Are you restricted in some way from putting up towers of say 200' ?
Is money a factor or are you building a government installation?
For lower bands, long arrays of wires can approach being "the best." Do you have a straight run of say 2000'?
Since you are a ham, do you want to also transmit on this "best SW Antenna?"


Based on the few molecules of info you've provided, I'd suggest what gov't and commercial stations often use... a log periodic yagi, rotatable and up on a thick tower about 80' to 150' depending on your favored frequency.  Better to use two towers: A log periodic at about 70' for 15 to 30 MHz and another one up about 150' for 3 to 15 MHz.  

While that's not "the best," it's within the financial means of many hams/SWLs... willing to spend about $100,000. (best to find land zoned industrial or farming).  

==========
Personally, as a very casual SWL I like the long random hunk of wired draped over the trees approach.

So he knows it was rude, perhaps just the smallest display of repentance overlaid with a dollop of self justification. K0OD typifies the unpleasant and arrogant and deserves to be ignored. These folk may have existed thirty years ago, I'm sorry they haven't died out. 
Perhaps what is needed is a NEWBIES Forum where sarcastic Elmers are named, shamed and banned. How about that moderator?
That sort of response is not helpful and not needed. The question was innocent and honest and didn't need the big boot response.
I followed this link because I thought it could prove useful to me!!!!!! I'll think twice before asking for help on this site.
How about my money back.

Sometimes those of us who are more experienced can be a little dismissive of others.
Being rude or condescending does not help.
Having said that K0OD has given some valid reasons why the OP's question could not be answered.
It is now time to move on.......
