DELTA-11 Datasheet, PDF (1/2 Pages) List of Unclassifed Manufacturers – Omnidirectional

Delta 11
ISM Stubby Antenna
Key Features
• Range of ISM frequencies covered
• 90.2 to 143mm long (depending on the frequency)
• ¼ wave radiating element
• Omnidirectional
• 2.15 to 3dBi gain
General Description
The Delta 11 range of antennas are high
quality ISM rubber flexi antennas intended
for mobile applications. The Delta 11 is a
great combination of good looks, quality
build and cost effectiveness. The Delta 11 is
used by a number of volume manufacturers
due to its quality / cost effectiveness.
The standard Delta 11 is tuned to the ISM
(Industrial, Scientific and Medical) radio
frequency band of 433MHz. Siretta also
offers this style of antenna in a number of
other ISM frequency bands which include;
433, 458, 869, 916, 151 and 173MHz. The
latter 2 frequencies are made using housing
143mm long, as opposed to the other 4
frequencies that are within 90.2mm long
housing. The Delta 11 antenna is suited for
short range, low power applications such
as license-free voice communications.
Mechanical
Bending Test
Put away from the connector of
line on 30 CM and bear 120g, fixed
the connector and then test the
Swing, swing Angle around each
60 degrees, swing 1000 times for
test characteristics. After 1000
times Swing have no any electrical
properties damaged.
Strength Test
15 pounds of static load on the wire
bottom lasted one minute. Have no
any revealed mechanical and electrical
damaged.
Pull Test
Between the Connector and Wire for
the Pull Test. Bear 7Kg Stuff have
no any revealed mechanical and
electrical damaged.
Vibration Test
With 1.10 mm and amplitude 33.30
Hz/SEC vibration frequency to the
X axis vibration 120 minutes, Y axis
vibration 120 minutes, Z axis vibration
240 minutes. Have no any
revealed mechanical and electrical
damaged.
