At one time I had a 50 foot Rohn 'push up pole'
with a 5/8 wave CB antenna on top. Guyed with Dacron.
Sitting on a coke bottle.
Worked FB but CB antenna was not strong enough to support
wire for top feed so had to feed at bottom.

| hi
|
| i'm looking for suggestions on raising 70 ft of aluminum tubing into the
air
| for verticals on 80m. what are others using: telescoping tubing?
| irrigation tubing? or what?
| most needed, what method was used to get it up?
|
| i've been using telescoping 12 ft lengths of .058" , starting at 2" dia
and
| found that abt 45 ft is the maximum i can tilt up by hand.
| if i were to push up the telescoping tubes, i would have to be 14 ft off
the
| ground as
| i push each section up and out from the ones below --too high for an 8
foot
| step ladder.
|
| for a base insulator, i have 4 ft lengths of solid plexiglass rods 1.875
inch
| dia
| which fit into the 2" dia , .058 bottom tube.
|
| 73, fred
