Quality Components Means Assured
Reliability
1
User supplied 3/8-1/4” suspension rope, black Dacron®
recommended.
2
2.5” glazed ceramic stress insulator.
3
1/8” double-braided black Dacron® UV, chemical
resistant rope.
4
13AWG insulated copper-clad steel wire w/mil-spec black PE insulation.
5 Spreaders
are pultruded fiberglass tubing, 36” x 1.5” OD x 1/8” wall, reinforced at
all points where wire elements pass with 5” x 1.25” OD x 1/8” wall
fiberglass inserts for added strength in these high stress areas. All
electrical connections are hand-soldered, fully stress-relieved and/or epoxy
potted within the spreaders.
6 All
connections and junctions between spreaders and wire elements are
stress-relieved, using our exclusive combination of 1/8” double-braided
Dacron rope and machine-swaged, twin-cavity aluminum crimps. This method
provides great strength and prevents any movement that would result in ware
and possible failure of these vital mechanical junctions under full load
conditions of wind and snow.
7 Hand-built
and fully tested, “true” balun is designed for continuous-duty at full rated
power. Each is housed in a NEMA 4” x 4” marine-grade enclosure, mounted on
a ¼” thick black UHMW-PE mounting plate with all stainless-steel hardware.
2” stainless U-bolts are provided for mast-mounting of antennas in
inverted-V configuration if desired. Standard coaxial connector is type-N,
with others available at additional cost. Full stress-relief for this
connector is provided, the coaxial feed-line is not. Feed-point impedance
is 50 ohms nominal.
8 Twin loads
are non-inductive and housed in 12” OR 10” x 2” OD x 1/8” wall fiberglass
tubes with heavy, epoxy-sealed polystyrene end-caps. All hardware is
stainless-steel and brass. Full strain-relief is provided by uniquely
designed suspension bridles comprised of 1/8” double-braided black Dacron®
rope, 1” polypropylene webbing and mil-spec black polymer hardware. All
connections are made using machine-sledged aluminum crimps.
No PVC,
or other small tubes or UV unstable parts! No other manufacturer makes
anything as rugged as these broad band models!
