BROADBAND DISCONE ANTENNA, MODEL BDA-210/A
Model
DBA-210/A is a broadband discone type active receiving
antenna system designed to operate over the frequency
range from 20 MHz to 1 GHz.
The antenna can be used on a ground plane as well
as off the ground plane on a mast, on top of a table or
vehicle. For
outdoor use, it is protected from weather by an optional
fiberglass radome.
The
antenna preamplifier uses 12-15 VDC at 15 milli Ampere.

PASSIVE BICONICAL ANTENNA, MODEL PBC-310/A
The
PBC-310/A is a Vertical Biconical Antenna designed for
transmit-receive application over the frequency range
from 30 MHz to 1 GHz.
The antenna can be used to transmit up to 500
Watts of Cw power. The antenna is intended for use in all weather conditions.
Model ABC-310/A is recommended, when used
preamplifier incorporated inside the mast, to improve
its sensitivity to weak fields.

PASSIVE CONICAL MONOPOLE, MODEL PCM-118/A
Model
PCM-118/A is
a broadband Passive Conical Monopole Antenna Primarily
designed for transmit-receive applications over the
frequency range of 1 to 18 GHz.
The antenna is linearly polarized and produces
onmidirectional radiation pattern with a nominal gain of
+2 dB in broadband mode.
The
antenna is protected from weather by a lightweight
fiberglass radome.
By incorporating an optional polarizers in side
