SUBJECT: Mobile Resonators as HF hidden antennas

Mobile resonators are small and easy to hide in comparison to a full size
HF antenna. They have there own faults as well. They require a good ground 
plane when not attched to a vehicle.

Experiments done here with mobile HF antennas have shown good results when
used as a base station antenna.

The most obvious and easiest install for a mobile HF antenna is the 
installation it is designed for. Mobile!

To take advantage of the 'no antennas' rule at most PUDs / condos / 
apartments, the designed mobile installation is best. In addition to this,
a coax can be run from the location of the mobile to the dwelling for indoor
operation. This provides a mobile / base operation with just the 
installation of the coax.

This concept also gives the operator the alibi needed if interference is
experienced by the neighbors. When they look out to see if you're in
the vehicle, nobody is there.

This design is good for bottom floor dwellers in apartments and any
'sneaky' mid-floor dwellers who can weasel a coax to their apartment.
Top floor apartment dwellers can hide the resonators in PVC pipe and
install the antenna on the roof of the building, if possible. It would
need to look like a vent pipe. I've seen some designs that even pop out
of drain pipes. This design may be a little too much for most amateurs.

Roof and tree mounting can be difficult at best. Installing these antennas
can be next to imposible for most dwellings. If you decide to install a
mobile resonators in other than the designed location, a good ground
plane is a must. This one factor may be your undoing in the stelth antenna
concept.

Painting the antenna to hide it can help. For night operation, flat black
or flat dark grey is recommended. Daytime ops require a background
blending scheme.

Further placement designs of this antenna is in works.
