i put the top one up this past friday.
all went pretty well, and no major setbacks.
the last time i installed one of these antennas, i bent the hoop sections so they were more circular.
this time i didnt bother with that, and while i know it does not have any effect on the signal radiation, i dont like the way the bottom has sort of a "clover-like" appearance to it. LOL
SWR ended up being about 1.3 across the regular 40.
it sits on a 30 foot push up pole with a 5 foot mast on top.
the push up pole is held up by a tripod bolted to a heavy metal base plate.
i did this because i am renting a house right now and cant attach anything to the house.
i push it up when i want to use the radio, and lower it down when i am done.
works well, but i havent made any DX contacts with it yet.
i blame the sun. LOL
