Actually you can get a bit cheaper than the Wellbrook - W6LVP has a loop that's almost 1/2 the price of the Pixel and Wellbrook antennas. And would you believe MFJ has one now too, that's about the same price range as W6LVP's? (just keep in mind that hams call MFJ 'Mighty Fine Junk' for a reason - some of their stuff is terrible...)

Besides the LA400 is not made to be outdoors. Not for a permanent mounting by any means. The 2 I just mentioned are. Here are the relevant links

The LA400 is way overpriced for what it purports to do - but don't let that sway you into thinking that wide band loops aren't any good. That's sheer and utter nonsense. There are many reviews out there of various Wellbrook (that have won several WRTH awards) and Pixel loops that say otherwise.

And here are over a dozen reviews (yes, user level, not really technical) of the W6LVP model (with the relay for transceivers which is meaningless for just receive performance)

Here are a few more links with reviews, some of which from our Loops wiki .

Now I'm not saying that a loop is a magic bullet for everyone, but it's quite clear that there are those that perform. Some of them are not nearly as expensive as a Pixel or Wellbrook.

I have no interest in a loop for HF but I'm curious as to the answer for OP's question: if he put the loop outside, as opposed to inside, and elevated it 10 feet or so up, would it work better than it does inside?

My guess it the answer would depend on whether he is on a second floor or not, and how much RFI he may need to avoid. At least, that would be the answer for most other indoor antennas (like the indoor wire I use presently).

My stock answer to this is-you tell us! Go hang it up in that tree and see for yourself. Here at my QTH, experimentation is how I found what works best in my environment. This goes to what boombox said about your particular situation.

I'm thinking of making something along these lines....

Loop Antenna.

I won't need the relay to desensitize it when I'm transmitting - mainly because I don't - and I was thinking about making the loop out of RG8 - just the connecting to the braid of course - maybe enclosing it in a extra layer of black irrigation hose which is UV resistant. I made a BC band loops a while ago which I don't use so the frame of that could come in handy....
