Thank you... I have been debating over the purchase myself.. we did recently move out of the city (HOA ****) onto an acre of land and just purchased the 1 acre lot next door for a future separate garage / workshop... 

Yes I am at that point where I want to hear that next lower level of signals I know are there.  Been testing an RBOG but still not quite what I was hoping for.

I will look over the reviews you sent and continue my research..

Thanks for the info

Hello Gary, did you consider before buying the SAl-30 on building your own? I saw QST did a how-to many months back.

Gary NC3Z

No, but I did make my own conversion from the Mark I to the newer Mark II. I know there are some who did build their own. I wanted a control box that looked more professional than I could cobble together.

If I had space (I have 8 acres but that still was an issue) I would have done several 600' beverages as they would have been more cost effective. But all my prime open space was taken up by the TX verticals.

Yeah, I whis I had more acreage for a bev but 2.5 acres is not enough and with a 2500sq house on the middle of the property really limits what you can do.

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.

Thank you... sounds similar setup to what I am looking to have.. I already have a 43' vertical that will work on 160 meters.. just do not hear all that great.

Question.. what is your Four Square Configuration?  i.e. how long down one side?  Also are you using the HF Preamp at all?

Thanks

W7AH

I used 98 ft sides because I wanted to use the 4-square for both 160 and 80m. The HF Preamp helps.

If anyone is interested, they recommend no more than 2% error based on side length... so 70' sides each corner should be within 1.4' with less than 1% being ideal.
