Erecting a Broadband Antenna Using a Vehicle for Grounding
This method is used if your MICOM-2ET-RDP is located in a vehicle or if a
vehicle is available and can be used for grounding. This will give better results
than earth grounding.
1.
Fit the grounding stake through the holes in the antenna spool. Pull out the black
handle on the spool. Holding the stake in one hand, use the handle to wind and
unwind the antenna wire.
2.
Unreel the antenna, laying it in a straight line along the ground.
3.
Tie the bare end of the long throw cord securely to the white eyelet on the antenna
wire, located near the small metal cylinder.
4.
Throw the weight of the throw cord over a branch of the tree, or any other suitable
place.
5.
The end of the antenna (load cable) will drop vertically from the suspension
point. Allow it to drape along the ground, and verify that the end of the antenna
is in contact with the ground.
6.
Position the vehicle so that the antenna can be pulled tense between the tree and
the vehicle.
7.
Tie the short throw cord to the white eyelet near the balun box.
8.
Secure the other end of the antenna to the vehicle, selecting a point as high off the
ground as possible (for instance a roof rack).
9.
Verify that the antenna is fully extended and pulled tight to full tension.
10.
Attach the clip at the end of the counterpoise cord to the tow bar of the vehicle,
or any other point on the vehicle chassis where a bare metal contact can be made.
The counterpoise cord can remain lying loosely on the ground and does not have
to be pulled tight.
Note
Select a smooth clear branch, so as to facilitate retrieval of the cord
after antenna installation.
Note
Painted, rusty or greasy surfaces will not provide good grounding.
