Thanks again

I lay my wire on the ground and have found that they are not as effective in the spring when the grass begins to cover them. I now lift them up periodically throughout the winter. Snow doesn't seem to make a difference.
Having praised them I am thinking of a SAL30 so that I can have low noise, directive hearing during the mowing months. I rolled my BOGs up a couple of days ago.

It is interesting not only because of the performance as well as that it uses RG6 but also how many different configurations can be created.
Anyone using one of these rxantennas ?
I purchased the RBOG pre-amp box, it works OK, however, from an engineering standpoint I did not like the +12 connector being an RCA jack. If that connector some how comes out, you have +12 exposed on the center pin of the RCA male. I made an adapter cable to power poles with a 1/2 amp inline fuse.
I'm about to start building a multiple K9AY array set up for End Fire feed. Next winter I will install the RBOG 1 to 2 inches above the ground to see how it works, maybe I need to go little higher.
I'm about to roll up the BOG, the K9AY loops stay up year around.
As they say " Your Mileage may vary".

PS: You might want to look at W3LPL's presentation on "Easy to Build Receiving Arrays For Samll and Large Lots". It a PDF file at the following address: https://www.contestuniversity.com/.../6.-W3LPL-Easy-to-Build-Low-Band-Receiving-...

Yes. Also W8JI’s site:

…. maybe the authority on Beverages, except for Harold “Bev” Beverage himself of course.
2 reversible beverages here, and another in the making. BOGs not an option due to critter and tractor ground traffic. Also the BOGs require periodic extraction from growing vegetation.

My transmit antenna uses elevated radials, I think that they maybe re-radiating noise which is hurting my receive.

Also, there are many excellent informative posts from knowledgeable hams on BOGs and RBOGs in the Topband archives:

Anyway the testing continues when I have some more solid results will share.
Finding the optimum placement of the RBOG is ongoing.
Contemplating a 4 square phased array.
But comparing the RBOG (180' of wire down) to the 43' vertical, the noise floor is slightly lower, but pointing just 2 directions I am limited on signals to compare but.. still working with it and hoping the better ground will help things.
