Q. What
simple, inexpensive antennas have consistently outperformed verticals,
dipoles, loops & even yagis mounted at the same (low) height above
ground on long-haul DX?
A. The WW3K HALF-SQUARE!
Q. What
is a “Half-Square”?
A. It is a Bi-Directional, Lambda (Full
Wavelength), Dual-Driven Element, Monoband, High-Gain, SCV (Self-Contained
Vertical),
High-Gain antenna which, when properly constructed,
offers:
1. Reduced ground losses yielding extremely high
efficiencies (up to 600% more efficient than the best commercially
available ground-mounted vertical costing
hundreds of dollars
more!)
2. Big-Gun DX performance at low cost, with no need for
expensive (dangerous) towers, rotators, etc.
3. Direct 50 ohm
coaxial cable match, with no need for a balun
4. Offers both QRN
and QRM suppression
5. Radiating portion of antenna is high to both
clear rf obstructions, and reduce ground absorption (wasted
power.)
6. Unobtrusive, stealthy & portable; suitable for
“restricted” locations.
7. Broadbanded; can work entire SSB or CW
portion of the band with NO
tuner required (entire band between 2:1 SWR
points in most installations.)
8. Extremely low Take-Off-Angle
(TOA) for maximum DX angle of incidence;
Broad Beamwidth; Superior side
rejection; Impressive gain figures; High
angle suppression
9.
Easy Installation; only two supports (typically trees, poles, houses,
etc.) needed.
10. Much less height required for low TOA than with
dipoles or yagis as shown in the chart below:
BAND----DPL./YAGI HT.
NEEDED-----HALF-SQUARE HT.
10 meters-----50-75 feet-----vs.------Only
13 feet!
15 meters-----60-90 feet-----vs.------Only 18 feet!
20
meters-----70-100 feet----vs.-----Only 25 feet!
40 meters-----100-200
feet---vs.----Only 35-50 feet!
11. Compact and Space-Conserving;
requires only slightly greater horizontal area than a 1/2 wave
dipole!
12. No radials or counterpoise required!
Q. What
kind of gain figures can I expect to obtain?
A. Up to 6dB
broadside, low (<20degree) TOA, at a 60-75 degree Beamwidth, with up to
10-15dB side rejection (depending upon mounting, terrain,
obstructions.)
Q. What makes WW3K HALF-SQUARES better than the
competition?
A. Many reasons! To name a quick few:
1. Made
in the U.S.A. by an “Active” Radio Amateur & Avid Contester
(made
by a Ham For Hams!) Remember: “Professionals” built the
Titanic, but an
“Amateur” built the Ark!
2. Only the finest materials are used in
construction:
- Budwig HQ-1 35% glass filled ABS copolymer coax
connector offers
18,000 psi tensile strength
- Coax fitting
protected by an integral Rain Drip Shield
- Flexible, Pre-Stretched,
black insulated #14 stranded copper wire won’t
kink & snap
- All
electrical connections are soldered, not twisted & crimped
-
Insulation on the elements prevents oxidation & detuning; adds
stealth;
increases life of the radiating elements
3. All
antennas are hand assembled + TESTED before being packed &
shipped.
Only very minor field adjustments may be necessary.
4.
Competitively Priced!!! (Generally much lower than the
“competition”)
