for Marine and Military Applications
For 30 years, Naval
Electronics has been a
design and manufacturing company for shipboard antennas and
The experience gained during this period, has gone into the new PR-400 series of active receiving antennas.
Care in design of mechanical and electrical components ensures years of trouble free, high performance, meeting the very special demands put on shipboard antennas.
The PR-432 active antenna is optimized for AM-SW Band reception from 100 kHz to 30 Mhz and the FM Broadcast Band of 88-108 MHz.
The antenna is omnidirectional and senses vertical polarization.
Custom Active Antennas are routinly made at Naval for Military Applications.

Compact Size - The PR-432 antenna is only 1 meter tall. The internal amplifiers make up for the relatively small size of the printed circuit receiving elements, delivering signals equal to much larger passive antennas. Output Impedance is a constant 50 or 75 ohms across the entire frequency range of the antenna, making an antenna tuner totally unneccessary. Omnidirectional reception pattern makes the PR-432 antenna perform equally on signals coming from all directions, while longwire antennas exhibit directionality.
In shortwave applications, short vertical antennas like the PR-432 demonstrate quieter reception with much less atmospheric noise than wire antennas, especially important on lower shortwave frequencies.
On the FM
antenna is subject to severe feedline losses, resulting in weaker
at the receiver's antenna input. The internal low-noise amplifier of
PR-432 increases signal strength before any cable losses are
delivering much stronger signal levels to the receiver. Passive
and directional couplers and outlets are available off the shelf with 2
4 outputs and pass the complete AM-SW radio band from 100 KHz and
Passives are ground isolated for use on ships.
