Active Radio Antennas
for Marine and Military Applications

For 30 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 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.

Active Antennas -vs- Longwire Antennas

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 Radio band a remote passive antenna is subject to severe feedline losses, resulting in weaker signals at the receiver's antenna input. The internal low-noise amplifier of the PR-432 increases signal strength before any cable losses are encountered, delivering much stronger signal levels to the receiver. Passive splitters and directional couplers and outlets are available off the shelf with 2 and 4 outputs and pass the complete AM-SW radio band from 100 KHz and higher. Passives are ground isolated for use on ships.
