Preparing the 2110 SSB Transceiver for use
38 2110 SSB Transceiver Reference Manual
The whip antennas are suitable for multifrequency operation. The built-in antenna tuner
automatically tunes the antenna on the first time a transmission occurs after selecting a
new channel. This occurs when your transceiver receives a call, or when you press PTT.
Alternatively, the antenna can be tuned to a frequency by pressing TUNE, then PTT. The
SWR of the antenna may be viewed by pressing TUNE. The whip antennas are suitable
for scanning ALE/CALM and Codan Selcall networks.
The whip antennas are designed for deployment on the antenna stud on the front panel of
the 2110 SSB Transceiver. The tape and knock-down whip antennas are suitable for
walking and listening for communication over short distances up to 100 km (60 mi),
using frequencies of 3–30 MHz. The 3 m (10 ft) collapsible whip antenna is suitable for
communication over short to medium distances up to 500 km (300 mi), using
frequencies of 2–30 MHz. Due to its length and rigidity, the collapsible whip antenna is
not suitable for walking and listening.
Long wire antenna and adaptor
The long wire antenna is suitable for multifrequency operation with the built-in antenna
tuner of the 2110 SSB Transceiver. It is approximately 10 m (11 yd) in length. The long
wire antenna is suitable for scanning ALE/CALM and Codan Selcall networks.
The long wire antenna and adaptor is designed for deployment on the antenna stud on the
front panel of the 2110 SSB Transceiver with the use of one support structure. The long
wire antenna is suitable for communication over short to long distances up to 5000 km
(3000 mi), using frequencies of 1.6–30 MHz. It is restricted to a fixed site for
transmission and reception.
Table 7: Advantages and limitations of a vertical whip antenna
Advantages Limitations
Quick and easy to deploy.
Tape and knock-down whips are suitable
for monitoring communications while
moving due to their flexibility and knock-
down properties.
Omnidirectional antenna, therefore it can
pick up signals equally in all directions.
Suitable for short-distance
communications.
Suitable for scanning applications.
Multifrequency operation.
Tape and knock-down whips unsuitable for
distances over 100 km (60 mi).
3 m (10 ft) collapsible whip unsuitable for
distances over 500 km (300 mi).
3 m (10 ft) collapsible whip unsuitable for
monitoring communications while
moving.
This antenna is more susceptible to noise
pickup such as that produced by welders,
electric motors, power lines etc. If used in
a noisy environment, degradation of the
received signal will occur.
