Art, I put one up this spring with the encouragement on this list. The L's are back to back, e.g. the 160M L points north while the 80M points south. The vertical sections are 45' and the spacing is about 18". Fed with a decoupling choke at the base over 32 65' radials.
My amp tunes up with no need for a tuner or matching network and I have been very pleased with the performance, even for local stuff out 300-600 miles all during the summer. Did a lot of comparison using WSPR mode into EU and OC and the L on both bands trounced the resonate dipoles, on both TX and RX, so they have since come down. I am considering adding a 40M element.
