When I built my shop I framed in the wall a verticle cable chase about 6-8" wide from attic down to the floor.  Pulling out or dropping in a cable is pretty easy.

I used to be able to wire up most anything, solder the very small stuff, etc.  But now after retina detachments, a retina central vein problem, issues with optic nerves, and several eye surguries - I no longer can do many of these types of things for myself.  I therefore am a customer of things that some may think a ham should be able to do for themselves.  And even if somewhat expensive I appreciate when a needed simple gizmo is available for purchase.

it's not a problem, there is a loss but so small as to not matter.  Go for it.

Here are pictures of my transportable 'ham shack in a box".  Moves to/from the RV motorhome, the house, etc.

Here is my ham shack and bench area.

I have a 18' pipe holding up a GAP Titan.  Anchored to the house with one of those inexpensive TV mast house brackets.  The bottom is held in place by slipping it over a piece of rebar driven into the ground.  Is very solid and has been up for a few years.

Hire a day laborer to dig the hole...

Sounds like you are planning to set up your own station at a club or other organized field day group venue.  Be sure and discuss and coordinate your activities with that group.

apply PB blaster in the morning, again in the afernoon, and some more in the evening - next day use the proper wrench and remove the nuts.  If still won't come loose - repeat the application.  After yet another day if still won't loosen, heat with a torch.

I would just make a hole and be done with it.  When you sell it put one of the plastic plugs in the hole.

If you to get lots of ideas, go onto one of the several jeep forums and search - lots of jeepers have 2M on board for the ability to call for help in case of a need.  Such as http://jeepsunlimited.com/forums/

Other applications print ok, correct - the problem is only with Thunderbird? 
When printing from Thunderbird the same printer is selected as with other applications, correct?

I have one of these on a OCF dipole I built.

ditto!

Yes, thanks.

Thanks, I have a 480, and agree it's a fine performer. 
This setup is more a transportable base station that will move from primary shack to motor home.

But let's not get off the question at hand regarding the mobile bracket.
