A couple months back, I had the Imax up 21' off the ground, and a friend of mine told me to cut 4 pieces of wire and put them on one of the U bolts, so I tried this and all the Imax would just tune then for was 10-17m bands....
Next thing I did was cut 6" off the top of the Imax, and tried this again, but the swr still wouldn't drop on 20m, so then all I used the Imax for was 10-17m bands...
I later took the Imax down and strung the G5RV across the back yard, and had bought me a LDG auto tuner for my 450D and just used the G5RV for awhile....
I just put the Imax back up a few weeks ago, and now it is on a 3' piece of pipe, mounted to a tree stump, and added 6 pieces of 14ga stranded copper wires to it, each one is 17' long and laid them each out at a 60 degree angle, and now it will tune for 20 and 40m easy.....now it talks great on 10-40m bands, swr runs a 1.1..
The Imax works great for these bands, think the A99 will work like this as well...
Dan K3BOA, was very helpful helping me make this thing talk, he is a good Elmer, thanks again Dan...
