I picked up a nice rugged electronics air-cargo shipping container at a local military surplus store to serve as my Go-Box:

Here is what I have in my Go-Box:

Icom IC-706MkIIG

Icom AH-4 tuner

MFJ 12 volt power supply

AC Outlet strip

AC extension cord

Random wire antenna for use with AH-4 (73′)

2 or 3 lengths of RG-8x coax

AH-4 tuner extension cable

If you have an Icom AH-4 tuner, you may be as bewildered as I was in selecting an appropriate wire length that would NOT inhibit you from working all the bands. I finally stumbled across an Excel file that somebody put together which builds a graphical chart showing the lengths to AVOID…and thus by inference which lengths are OK to use.
