I will support that "All bands" Conditions vary.. I once sat in Detroit, at my Police Radio Desk, and chatted with a construction company counterpart in Anchorage Alaska on 42MHZ. he and his could hear me clearly as could I and mine.
Now that's what we call a band opening
All bands is good.. NOTE: short verticals tend to not work all that well on low bands though there is an interesting 75meter design in the current QST (Which I just got out of my mail box) Looks easy to build. My preferred antenna is wire, 100' long, on one end I have a nylon line tied on, the other end of the line has an eye bolt embedded in 2 pounds of concrete (Take a kool aid, crystle lite or Wylers sugar free drink mix cylinder and fill it with concrete, shove bolt through cap, nd shove it into wet cement, apply cap, let harden, I put a nut on the bolt to help it stick in the slop)
The other end has a nylon line attached at about six feet out, the end hooks to a KAT-1 (Kenwood Auto/Antenna tuner) which is fed by my TS-2000 The nylon line goes to an open eye bolt (hook) near the roof line of the MH originally put ther for something else, then ties off to anything handy at eye level (Bike rack normally)
David & Golith style toss the weight over tree limbs
NOTE: this will nto work in Alaska (no trees)
Optionally. 12 or 18 foot painter's pole, and guy lines for the far end (This will work in Alaska)
