The Penetrator
The Penetratorisa
full size
%-wave,
omnidirectional
antenna. A full sized radiator with a
,lower radiation angle concentrates
power closer to the ground. The antenna accepts AM,
'FM,
SSB, and DSB signals, It can be fed by any standard 52-ohm coaxial cable suchas
RG-8/U
and RG-58/U,
For runs
over
50ft
RG-8/U
is recommended,
The Penetrator fits any masting material up to 1%" aD. A 1%" f=llumbers pipe is highly
recommended
for mast use due to its low cost and high strength.

( ) Select the base assembly (item 12), the two radial plates (item 1), the M1 assembly
(item 13), and the upper insulator (item 11).
( ) Refer to Figure 1 and loosely'assemble these parts as shown, using tHe %" x 1" screws
and associated
hardware. Do not tighten at this time.
NOTE:
Make certain the end with %"diameter
holes, 10cated3fa"from the end, are down",
and aligned with the holes in the insulator. Remember to point the two smaller holes,
(located 5%" and 13" from the bottom end) away from the base bracket These will be used
to attach the matching rod assembly.
( ) Fasten the M1 assembly to the insulator with
the #10 x 13;4"screw (item 26) and
associated hardware (item 35and
41 ).Tighten
securely.
( ) Referring to Figure 2, assemble the
Ya"
x 25" R1 tubes (item 3) into brackets, align the
holes and fasten with %" x 11!2"screws, nuts, and lockwashers
(items 24, 34, and 40).
( ) Remove
the two rod support insulators (item 21 ) and the two #1 0 x %" type T screws
from the parts pack and attach them to the M1 assembly as shown in Figure 3.
( ) Refer to Figure 6 and assemble the radiator tubes M2, M3, M4, the top radial assembly
and the radial elements. Refer to the compression clamp detail for their proper assembly.
