Two GRARA friends just helped me take down this antenna from a friend's roof. It's in good condition. I have an optional roof tripod mount, too, if interested. I've taken it apart just enough for transportation and easy reassembly. No radials required for this puppy.
Price new is $399. First $100 takes it. Have original manual, too.
Here are the specs from the GAP website:

THE EAGLE DX
The Eagle is the smallest antenna in the GAP product line. Its development was the result of your requests for a low profile, high efficiency GAP antenna. The Eagle DX-VI weighs just 11 pounds and can be installed almost anywhere -- at ground level, on a pole, on your roof or atop a tower. It is essentially a set of vertical dipoles -- the optimum singular DX antenna. No traps, coils or transformers are used to achieve multiband operation in this antenna either. Why is that significant? Traps are the "weak link in the chain" of a multiband antenna.
Critical to the design of the GAP Eagle was the requirement to permit operation anywhere on all of its designed frequencies. The Eagle provides full coverage with a VSWR less than 2:1 on 40m, 20m, 17m, 15m, and 12m and approximately 500 KHz on 10m without readjusting. 10m operation is further optimized with a supplied extender. Compare that performance to any other low profile vertical. With the Eagle, as with all GAP antennas, you will not need to buy a tuner. If a rare DX station appears on 7.050, but, you normally work the SSB nets around 7.250, just slide the VFO and key the rig!
If the band is wide open, you might work a LU6 with a coat hanger, but when conditions are less than perfect you want the highest S meter reading an antenna can provide. Efficiency is critical. The efficiency of the GAP Eagle is without equal. It has no traps, transformers or matching coils to rob transmitted or received power. For the highest S meter, choose a GAP Eagle.
