For
many years, Naval Electronics has been a recognized design and
manufacturing
company for shipboard antennas and CATV/MATV-systems. The experience
gained
during this period, has gone into the new VPA30 active receiving
antenna.
Thorough design of mechanical and electrical parts will give years of
troublefree,
high performance, meeting the very special demands put on shipboard
antennas.
The VPA-30 is a very compact active antenna optimized for AM
reception
from 100 kHz to 30 Mhz and the FM broadcast band of 88-108 MHz. The
antenna
is omnidirectional and senses vertical polarization.
