Considering the purchase but do not want to pull the trigger until I get a better idea of what I am getting into here.. have plenty of space now to put on up.
I do not have any experience with the antennas, however, below please a couple of E-ham review links(not clickable) that you should take a look at. The German review will make you a believer, the DXE system was compared against beverage antennas.
I have been looking at this set up for a while but can't get my self to dig into the wallet. I have an acre in town, the TX antenna uses elevated radials, I'm worried about the radials re-radiating noise. Also read the DXE manuals regarding RX antenna placement near fences, and buildings. I have confirmed 68 countries in the last two winters using a K9AY receive loop set up and a reversible BOG. If your like me you need to hear that next lower level of DX signals . Hope this helps. At my QTH the BOG and K9AY are about equal.
Hope this helps, It raining here so back to winding transformers for a multi K9AY array in an end fire configuration.

I will say the Hi-z or YCCC 4sq or 8 circle are ur best chaises . How well it works will depend on how quiet ur location is . Some are claiming good luck close to fences or metal buildings . I don't think theirs a one recipe fits all . I find it very exciting to hear the rare DX on the low bands , making all the work worthwhile .
I run a SAL-30 and I have been blown away by it's performance on the low bands. I can hear things that others without a RX antenna can't hear.
In January I installed a DX Engineering 160m Thunderbolt Vertical Antenna for transmitting on 160m and a DX Engineering Receive Four Square System for receiving both 160m and 80m. With the help of these antennas, FT8, and a FLEX-6600 I was able to go from about 50 countries to more than 100 confirmed countries on 160m in about 4 months.
At least for me, the DX Engineering Receive Four Square System worked well on both 160m and 80m, but I do not know how it compares with other receiving antennas.
I should mention that generally I used two slices on my FLEX-6600, where the 4-square was used as the receive antenna on one slice and either one of my 160m dipoles or the Thunderbolt 160m vertical was used as the receive antenna on the other slice. As long as I had the 4-square switched to the right direction, it generally performed better than the other receiving antenna, but occasionally on FT8 the best receiving antenna would switch from one 15 second period to the next. Perhaps that was due to the large distance between the antennas.
There are plenty of good reviews of the DXE array on Top Band, etc., and in my opinion it is a good choice for 160/80M. But since I don’t have a beam antenna of any sort for the higher bands, and since the beverages are not very directional on the higher bands, I’d probably go for the Array Solutions Shared Apex Loop (SAL) to augment my beverages. They make 3 versions, each optimized for a range of frequencies (frequency range of each is quite large and they overlap), take up much less real estate than the arrays, and seem to stack up quite well against the arrays:
And an interesting video of the SAL vs. the HI-Z array:
Array Solutions make great products, and Jay, the owner, is always responsive to questions.
I'm on a fairly heavy wooded and brush lot and would be clearing some for the system, just wondering how much work it will be..
Second question, they mention staying away from fences (wire fence in my case), how far would be acceptable? again 70' sides.. 10', 20', 50', 70' what is an acceptable distance?
Just trying to figure out what I might be getting myself into here.
So at this time I have put together the array in the back corner with 35' sides (less to clear) and have been testing. First, at this size array the delay control lines are critical, side spacing is critical for best performance. I am also working with poor soil conditions for grounding (I can take an 8' ground rod and shove it in the ground by hand about 4'). I still have a few things to do to improve on the array but here are my initial thoughts.
First I do not notice an increase in signal strength compared to the 43' vertical I have, however what I do see is a LARGE reduction in noise floor. With the 43' Vertical I used to spend lots of time trying to filter out all the noise to hear a station, now I simply flip over to the array, get it pointed the correct direction for best signal and I can hear them. Second I can now reduce static crashes greatly by pointing the array a different direction (HUGE bonus here in Fl).
I do have a few more things I still need to do, one getting the Feedline current choke in place (ran out of ground rods). I still need to get the sequencer setup (right now just listening) and I think I will use a preamp to help boot those weak signals a bit. Lastly if all goes well I may have to do the ole stack 2 ground rods on each corner (16' depth) I did this on the 43' vertical and it made a noticeable difference even with 36 ground radials down.
So far, I'm impressed.. even at 35' sides the array works well and has helped me to hear those stations that I could not hear before.
