Installation of Tubing Clamp
Select the proper size tubing clamp as shown in
the chart. (See Figure 6). When installing the
clamps, place the clamp near the tube end with
the top of the clamp over the slot in the tube as
shown in Figure 6.
After adjustment of the tubing lengths, tighten
the clamp with a 5/16 inch nut driver, socket, or
open end wrench until the tubing will not twist
or telescope.
VSWR Charts
These VSWR curves are typical for this
antenna mounted 70 feet above ground,
horizontally polarized. Similar curves can be
expected for this antenna mounted at least 30
feet above ground. DO NOT try to tune this
antenna for low VSWR at ground level.
