Makes sense for lots of locations. Using batteries to buffer a smaller 
gen that can support a power amp but run in economode means dragging 
much less weight and space for the gen and fuel. George first used that 
about ten years ago using DC powered power amps. Once I told him about 
RIB a couple of years ago, AG6EE has been doing both it with his setup 
to activate difficult VHF/UHF grids in the Rockies, the Sierra, and the 
high desert. He's also built big amps that run on 48VDC and are water 
cooled. He's doing Es, tropo, meteors, and EME.

I see some of you are interested in preamps.  Please check this unit out.
Preamps for 160/80/40/30  multiple radio outputs, Adjust gain and
attenuation by band.  And includes great bandpass filters all in one
package.

To make it a no-brainer use it for a couple of weeks and if you don't think
it improves your RX on the low bands return it in new condition and
original box for a full refund.
We think it's that good.
