I was admiring your tower and antennas on QRZ.com. I'm toying with taking
down my three-stack of SteppIRs (they are falling apart) and replacing with
something with less moving parts ;-)
Are your interlaced Yagis homebrew or commercially made?

Subject: [TowerTalk] Dropping guys
I have done this a number of times (see the photo of previous tower loading
on qrz.com KS9K and/or N4TZ (same tower)....
Presently I have 5el 20 on 48' boom and 3el 40 on 48' boom on top of tower,
with three 10/15 26' boom antennas and another 48' boom 20/40 antenna on
ring rotors on the sides of the tower. ALL were put up with the 'dropping
the guys'
method.
You start with a pulley at the top of the tower (in my case, a large beefy
3" x 3" x 1/4" angle two feet long U-bolted in middle to mast with two
pulleys, one on each side of angle to pass the pull cable from my hand
winch up the tower and back down again, to pass over the rings without
rubbing on things) After rigging the tower, you start with the antenna at
the bottom of the tower, hooked to your pull cable; I used a pair of slings
to make an inverted Vee connecting the boom to the pull cable, balanced.
Now, with the antenna at the bottom, crop TWO of the three guy wires at the
lowest level; i.e., disconnect them at the ground anchor. Walk the guy
wires into the tower and pass the guys behind the antenna next to the
tower. Then, winch the beam until the beam is just above the first guy
point on the tower; stop everything and reconnect the two guy wires to their
ground anchors. Now, drop two of the guys from the next level the same
way, walking the guys behind the antenna. Again, you want the dropped guys
to lie straight down the tower so they don't get in the way of the antenna.
Now, raise the antenna past the second level of guys on the tower, reconnect
the guys at the ground level, and repeat as frequently as necessary.
This can all be done by one person, with everything done on the ground
except the very initial rigging and the final connections.
