LOWERING THE ANTENNA
The antenna should perform in winds up to around 40 MPH. Ice is definitely a
concern for any antenna. If winds above 40 MPH and/or ice are expected, you
must lower the antenna to protect it from becoming damaged.
WARNING!
For safety reasons, do not attempt to lower (or
raise) the antenna when winds are above 10 MPH.
Two people are recommended to lower the antenna to prevent injury to yourself
and to prevent damage to the antenna.
To lower the antenna:
1. Disconnect the vertical element wire from the unun or remote antenna
tuner.
2. While standing opposite each other, your helper should grab the bottom of the
base tube near the pipe mount clamp.
3. Keep your back to the wind and grab the base tube higher up – near shoulder
level.
4. Working together, carefully lift the antenna straight up and off of the pipe and
then quickly lower the bottom of the base tube straight to the ground, keeping
the antenna as straight as possible in the vertical plane.
5. Now, have your helper apply light foot pressure to the bottom of the base tube
to keep it on the ground as you slowly walk the antenna down into the wind.
