FSG 2T PS
Portable VHF/AM Airband Transceiver
26 DITTEL  D10077 May 2010
4.4 Antenna - Antenna jack SO 239
DANGER!
NEVER TRANSMIT in closed vehicles, aircraft or inside
buildings with the spring steel band antenna! This may cause
malfunction of the avionics, trigger the airbag or mix-up
electronic equipment! Always operate the radio with a
suitable external antenna!
NEVER OPERATE the radio without any antenna!
Already a transmit power higher than 1 Watt creates very high
electromagnetic field strengths in close proximity to
shortened antennas (e.g. rubber helix antennas). This causes
a high radiation exposure for persons and may produce
sparks under certain circumstances!
IMPORTANT!
A good antenna is the best RF amplifier!
Your radio is only good as the antenna!
As portable radio used in the open the FSG 2T PS is usually operated
with the spring steel band antenna (Article-No. F10345).
The spring steel band antenna, connected to the SO 239 antenna
jack
10
, can be replaced by any other 50 antenna with UHF type
PL-259 cable plug and a frequency range of 118 137 MHz
minimum.
When the FSG 2T PS is operated in open, non-metallic or wire mesh
balloon baskets we recommend our Balloon Antenna BFA 1.
To operate the radio in aircraft or ground vehicles a suitable external
antenna should always be used.
For long range operation a base station folded top antenna, grounded
for lightning protection, is recommended.
Ensure the plug of your antenna or antenna cable is securely
tightened.
If the spring steel band antenna is used, adjust it in a vertical
position by tightening the screwed cap and wing screw.
4.5 Microphone Socket
The hand-held dynamic microphone with push-to-talk switch (Article-
No. F10346) can be replaced by any other dynamic microphone (200
to 600 Ohms) with PTT switch or a head-set for dynamic type
systems with additional PTT switch (mating 5-pole DIN plug: Article-
No. E08834, wiring to station, refer to Circuit Diagram PS).
Plug microphone, ensure the plug is secured by twist-lock cap.
