[TowerTalk] Portable Tower Question

[RICHARD BOYD]

Right, I've done them single handed many times.  I have 14 of them here -- nine of my own and five belonging to others -- we use them for Field Day and anything else we think of during the rest of the year.  In addition to moving the tubes separately from the base ("launcher"), N3OC showed me another trick -- leave the rack for the tubes at home, which makes loading the tubes into a minivan, back of an Expedition, etc. very doable.  73 - Rich, KE3Q

  I don't want to start a war...but with all due respect to Jamie,
  I have to disagree with the notion that AB-577 movement and
  installation can't be one-man jobs.  I own three of them, and
  have transported and erected one or more several times by myself
  with absolutely zero assistance.

  The trick for transporting them (i.e. - loading in a truck bed
  is to pull the tubes and carrier out, move the pieces, then
  reassemble in the truck bed.  Of course it adds 10 minutes
  or so to the process - but these sorts of things shouldn't be
  done in a hurry anyway.

  My typical one-man installation time for a standard 50-footer
  runs about 1-2 hours, depending on the complexity of the antenna
  stack (long VHF yagis, preamps, HELIAX, etc.), and includes
  shoveling a level pad in hard-packed decomposed granite soil.
  Sure, I get some exercise in the process, but everything has
  always progressed smoothly.

  So far, my only problem with the AB-577 system is that the
  standard guy stakes are too short for handling high gusting
  winds (75-90 MPH w/ long gusts 95-110 MPH)...and forget screw
  anchors in our soil.  You might as well try to screw one into
  cured concrete.  I'm considering some concrete base pads and
  guy points at home for semi-permanent use.

  Good luck & 73,
  Dan  KB5MY/6
