all birds are repelled by ultrasonic sound waves. For best bird
control, use the Broad
Band Bird Control ultrasonic repeller. The BroadBand
Pro combines audible scare noise and ultrasonic sound waves in a
special combination that will confuse and scare birds and animals.
BIRD-X introduces QB-4, the newest, most powerful ultrasonic weapon ever
available in the war against pest birds. The QB-4's four Piezo ceramic speakers emit
overlapping patterns of ultrasonic sound waves that zero in on the birds (but people can't
even hear them). Mount the QB-4 in any direction - on any surface. Just plug it into any
110vAC outlet and watch your bird problems fly away. Each
ultrasonic QB-4 will cover 40 feet from center in all directions.
This is an area of 80 x 80 or 6,400 square feet!
HOW IT WORKS...
The new BIRD-X QB-4 uses solid-state electronic circuitry to produce harsh, but harmless,
UHF sound waves. These sound waves are targeted at overhead bird infestations. Their
frequencies are above the human hearing range, so most people are not even aware of them.
Four powerful Piezo ceramic speakers, placed 90 degrees from each other, produce a
dispersion of overlapping "fans" of sound for full 360 degrees coverage. The
QB-4 may be regulated to maximize effectiveness. Speakers may function at a constant 20
kHz, modulate between 20 and 30 kHz at different speeds (producing a "warble")
or in a combination mode which alternates constant and "warble" output in 12
second bursts. The speakers can also be "sequenced" (in rotating order) at
speeds from 10 to 110 rpm. The QB-4 plugs into any convenient 110 volt/ AC outlet and uses less
current than a 10 watt bulb, costing only pennies a day to operate. Harmless to birds and
The irritating sound waves produced by the QB-4 will not harm birds, but
will attack them aggressively in any enclosed or semi-enclosed areas where they roost. The
adjustable variations in pitch and sequencing make it difficult for the birds to acclimate
to any constant sound pattern. Install QB-4 wherever birds infest.
QB-4 is designed to act as an important aid in routing birds from their
infestations in plants, warehouses and semi-enclosed locations such a loading docks,
railroad sidings, tunnels, breezeways, underpasses and storage sheds. Installation
couldn't be easier. There's no "top" or "bottom" to the unit, so it
can be mounted in any direction - on any plane - with screws, nails, wires or adhesives.
QB-4 has been developed by BIRD-X, the worldwide leader in bird repellent
products and systems.
