I recall ads showing a "Christmas-Tree" of `Squalo' anatennas with the 40 Meter model on the botttom, and the other bands arrayed up the mast. This makes transportation easier. It performs well and excellent on 20 meters but I noticed my 20 meter aluminum dipole seemed to get a better signal on 20 than does my G5RV. 5 pounds, anyone can store this, use this and move this with no problem. Thanks for your terrific post. All available for amateurs, schools, hobbyists, government, and wholesale buyers. If needed, it can be disassembled into a very small bundle no longer than the longest element. It is precision CNC made and developed by Bob himself.
