Good quality flooded RG-6 laying on the ground (BOG) might be an easy install like before contests at some locations. However I have no idea on how this would perform compared to an elevated version. If the directivety is maintained and the S/N ratio is still usable then such a concept would be worth considering. Such an installation might also be considered for DX-peditions where supports for a normal Beverage are just not available. Even for a short term use a normal consumer grade 1000 foot roll of RG-6 is competitive with the same amount of #12 or 14 THNN and certainly more competitive than 1000' of higher grade ladder line. It is nice however having a vendor who offers a unique of the shelf solution and it would nice to get some feedback on A/B checks with the conventional Beverage.

After looking at their literature it appears to me that this is nothing more then two beverages, one in each direction, with the "feed unit" being, perhaps, a couple relays. I don't see the merit in using RG6 as the beverage wire: its heavy, will need more supports, and compared to other solutions, perhaps more expensive. And the fact that the feed unit can be placed anywhere along the antenna? I must be missing something clever because all that would seem to do is make one direction's wire longer and the other shorter?

Since the antenna is a transmission line, with suitable end and center transformers, the feedpoint can be placed anywhere and the full length used.

With different transformers, any reasonable type of transmission line can be used.
