GeoTool
makes the PERFECT mount for Little
Tarheel II, Tarheel Model 75A "Stubby", HI-Q Hi-Sierra Sidekick, MFJ-1662, and any other Screwdriver
Antenna utilizing a 3/8"-24 single point mount system. The strong, clean design of the ISM-1 Screwdriver Antenna Mount is shown above,
with
a 3/8"-24 mounting bolt. Simply screw your antenna onto the mount, and
plug in the control line. Your coax attaches inside the mount using the
same
solderless connectors as our other HF mounts. This really is the strongest,
and best grounded mount for this purpose. It puts the
antenna up where the whole length will radiate. Click here
for installation instructions and more photos.

MOUNT
SELECTION CHART
The
chart below shows the aproximate dimensions of our mounts. Be sure to
include the
measurements of your stake pocket in your order. All mounts are
slightly
smaller than the
stake pocket on purpose, and a snug fit is obtained by shimming the top
of
the mount with plastic electrical tape. This avoids the problem of
oversize mounts cause by variations in the manufacturing of the trucks.
When you order, please list the
stake pocket dimensions, particularly the depth, and the make, model
and year
of your truck..... Thats
all I need to fit you with the correct
mount. To
see if our mounts will fit your truck, refer to
the chart below.

* Top
measurement. The
inside portion of the Pre-2006± Tundra mount is 1.5x2.1 inches,
the inside is
offset flush with either the inside or outside of the top opening.
Check your
stake pocket and you will see
the narrower bottom portion. The 'H' model fits these trucks.
**
All
VHF-A mounts are
5.65 inches long. All other VHF mounts are 5.75 INCHES long. Spacers
(stainless steel washers) are provided with
all
mounts to align the top of the mount even with the top of the bed
rail. Because pocket depths vary, it is important to give me the
depth as accurately as you can. The top dimensions almost always
fit, but it is a good idea to send them along too.
