I need some expert opinions on my future stacking problem. I am going to
put my
Force 12 5BAD 5-band antenna (72 lb weight, 10.8 sq feet wind load, 33 foot
boom)at the top of the tower, maybe 1 foot above the Rohn 25 flat top
section with a thrust bearing there. Then I have a M2 6M7JVC 7-element 6
meter yagi (with a 30'8" boom, 17 lb weight, 2.5 sq feet wind load) to go
above it and then finally a Force 12 EF-140 40-meter dipole (44.5' element
length, 1.9 sq feet wind load, 12 lb weight).
Which antenna should go above the 5BA? I figure the 6 meter as there would
be less interaction between it and the HF antenna than the 40 meter one?
What problem would I experience with the dropping of the ends of the
40-meter dipole interfering with the other antennas? I am supposed to mount
it at a 90 degree angle so its length is parallel with the boom of the other
two antennas - that puts its ends in front and in back of the two other
antennas??
Appreciate any input.
