[TowerTalk] Utility Pole as Beam Support

[Mickey Baker]

A pole like this is a great find.

A pole set crew with an auger can plant your pole properly in short order.
Digging a hole deep enough to plant it safely is a big job. Think about
hiring a local pole setter. It probably won't be as big a cost as you
think, if they can get the truck to the pole's location. If you plan
properly, they may be able to help you get your initial antenna installed
at the top of the pole. You're likely going to need a crane for the initial
installation.

The next step (pun intended) will be to create a way for you to reach the
top of the pole, unless you intend to hire a bucket truck every time you
want to work on your antenna.

The technique is called a "pole step" - the steps near ground level are
typically done with a mounting plate and lag screw so that you can remove
the step, and those higher are simple lag bolts with a step built in - you
drill a pilot hole in the pole and turn them in.

There are BSP's that set forth spacing and arrangement... but just make
sure you and your friends can reach each next step, and that you have a
level place to stand where you're going to be working at height.

Be safe. Be conservative when loading antennas, poles can loosen with
sudden torque loads and actually turn, but you should be fine with most
tri-band HF beams.
